%\section{Introduction}

In \hypertarget{eformsPkg}{this} document we describe the support for \app{Acrobat} form elements
in an {\cAcroT} document. The \textit{PDF Reference} indicates there
are four different categories of fields for a total of seven types
of fields.
\begin{questions}

\setbox0=\hbox{(d)}
\def\I#1{\makebox[\wd0]{\color{blue}(\hfil#1\hfil)}\ }

    \item \textbf{Button Fields}
        \begin{description}
            \item[\I{a}] \textbf{Push Button}
            \item[\I{b}] \textbf{Check Box}
            \item[\I{c}] \textbf{Radio Button}
        \end{description}
    \item \textbf{Choice Fields}
        \begin{description}
            \item[\I{a}] \textbf{List Box}
            \item[\I{b}] \textbf{Combo Box}
        \end{description}
    \item \textbf{Text Fields}
    \item \textbf{Signature Fields}

\end{questions}
The {\cAcroB} now supports \textit{signature fields}. Using the
command \cs{sigField}, an unsigned signature field is created.
The field can be signed, either by using \app{Acrobat}, or programmatically
from a {\LaTeX} source, but you need to use \textsf{aeb\_pro} and to
create the PDF using \app{Acrobat} Distiller.

The \textsf{hyperref} Package (Rahtz, Oberdiek \textit{et al})
provides support for the same set of form fields; however, not all
features of these fields can be accessed through the
\textsf{hyperref} commands.  I was determined to write my own set
of commands which would be sufficiently comprehensive and
extendable to suit all the needs of the \cAcroB.  All the quiz
environments have been modified to use this new set of form
commands, in this way, there is a uniform treatment of all form
fields in the \cAcroB.

\redpoint The demo files for {\eForm} support are
\texttt{eqform.tex}, for those using the \textsf{\app{Acrobat}
Distiller} to create a PDF document, and \texttt{eqform\_pd.tex},
for those who use \textsf{pdftex} or \textsf{dvipdfm}.

\section{Package Requirement and Options}

Prior to \textsf{Exerquiz} version 5.9, \textsf{eforms} was
an integral part of \textsf{Exerquiz}. I've now separated the two, making
\textsf{eforms} into a stand-alone package that is called by
\textsf{Exerquiz}.

\subsection{Package Requirements}

The \textsf{eforms} package requires \textsf{hyperref} (a newer version)
and \textsf{insdljs}, a package that is part of the {\cAcroB}.

\subsection{Package Options}

The \textsf{eforms} package has the usual driver options:
\begin{Verbatim}[xleftmargin=\amtIndent]
dvipsone, dvips, pdftex, dvipdfm, dvipdfmx, xetex
\end{Verbatim}
The package also works correctly with the \textsf{luatex} executable.
Informing the package what driver you are using is important, because each
driver has its own code that needs to be used to create form fields. For
dvips, you should use
\begin{Verbatim}[xleftmargin=\amtIndent]
\usepackage[dvips]{eforms}
\end{Verbatim}
The \textsf{eforms} package now does automatic detection of
\textsf{pdftex} (including luatex) and \textsf{xetex}. If the \textsf{web}
or \textsf{exerquiz} package is used, \textsf{eforms} will use the driver
defined in these earlier included packages.

\newtopic A minimal document is
\begin{Verbatim}[xleftmargin=\amtIndent]
\documentclass{article}
\usepackage{eforms}  % <-- the driver is pdftex or xetex
\begin{document}
    % Content containing form fields, such as...
    Don't \pushButton[\CA{Push Me}]{myButton}{}{12bp},
    I fall down easily.
\end{document}
\end{Verbatim}
\noindent The \textsf{eforms} package brings in the \textsf{hyperref} package
and passes it the driver, so there is no need to specify
\textsf{hyperref}, usually. If you wish to introduce \textsf{hyperref}
yourself with specific options, place it before \textsf{eforms}.

If you use the \textsf{exerquiz} package, \textsf{exerquiz} brings
in the \textsf{eforms} package and passes it to the driver.

\subsection{The \texttt{preview} option}

Use the \texttt{preview} option if you use a \texttt{dvi} previewer
to view your document. When \texttt{preview} is taken, a frame box
is drawn around any form field created by \textsf{eforms}, making
the position of the field visible in the previewer. This makes it
easy to make any additional adjustments for the position of the
field. Turn off this option when you build a PDF file.

\subsection{The \texttt{useui} option}

The \texttt{useui} option includes the \textsf{xkeyval} package, and
defines a number of key-value pairs that are used in the optional
arguments of the form fields and links. These key-value pairs are
more ``user-friendly'' to use. See
\hyperref[useui]{Section~\ref*{useui}}, page~\pageref*{useui}, for a
description of these key-value pairs.

\subsection{The \texttt{unicode} option of \textsf{hyperref}}

The \textsf{eforms} package will obey the \texttt{unicode} option of
\textsf{hyperref}. Whenever this option is taken in hyperref, for
certain keys (namely, \cs{V}, \cs{DV}, \cs{TU}, \cs{CA}, \cs{RC}, and
\cs{AC}), standard latex markup may be used to enter the values of
these keys, for example, in a text field, you might set
\verb!\V{J\"{u}rgen}!. This key-value pair will produce a field
value of ``J\"{u}rgen'' in that text field.


\section{Form Fields}

The \texttt{eforms} support for {\eForm} defines seven basic (and internal)
commands for creating the seven types of form elements. These seven are used
as ``building blocks'' for defining all buttons, check boxes, radio buttons
and text fields used in the \texttt{exerquiz} quizzes; and for defining seven
user-commands: \cs{listBox}, \cs{comboBox}, \cs{pushButton}, \cs{checkBox},
\cs{radioButton}, \cs{textField}, and \cs{sigField}. These user commands are
the topic of the subsequent sections.

Each of the above listed field commands has an optional first
parameter that is used to modify the appearance of the field,
and/or to add actions to the field.  This is a ``local''
capability, i.e., a way of modifying an individual field. There is
also a ``global'' mechanism. Each field type has its own
\cs{every\anglemeta{FieldTypeName}} command. For example, all buttons
created by \cs{pushButton}  can be modified using the
\cs{everyPushButton} command. See the sections on
\nameref{CheckBoxes} and \nameref{RadioButtons} for examples and
additional comments.

\redpoint The local modifications (the ones inserted into the
field by the first parameter) are read \textit{after} the global
modifications, in this way, the local modifications overwrite the
global ones.

\paragraph*{Key-value Pairs.} The optional first parameter of each of the form and link commands take
two styles of key-values:
\begin{enumerate}
    \item \textsf{eforms} KVP: This is the key-value system originally developed, each KVP has the form
        \cs{\anglemeta{key}\darg{\meta{val}}}. Through these keys, you can set the appearance of a form or link, and
        set the actions as well.

     \item[] The \cs{presets} key is useful for developing collections of pre-defined
        key-value pairs for insertion into the optional parameter list. For example,
\begin{Verbatim}[xleftmargin=\amtIndent]
\def\myFavFive{%
    \BC{1 0 0}\BG{0 1 0}\textColor{1 0 0}\Q{2}\CA{Push Me}}
\end{Verbatim}
Later, a button can be created using these preset values:
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\presets{\myFavFive}
    \A{\JS{app.alert("AcroTeX rocks!")}}]{pb1}{}{11bp}
\end{Verbatim}

    \item[] The \textsf{eforms} KVP system is explained throughout the manual, a complete listing
    of all supported KVPs is found in the \hyperref[appendix]{Appendices}, page~\pageref{appendix}.

    \item \textsf{xkeyval} KVP: When the \texttt{useui} option is taken, key-value pairs are
        defined of the form \texttt{\anglemeta{key}[=\anglemeta{value}]}. The key-value pairs are actually a value of
        a special \textsf{eforms} key, \cs{ui}. The value of \cs{ui} consists of a comma-delimited list of
        \textsf{xkeyval} key-value pairs.

    \item[] This style of key-value pairs also has
        a \texttt{presets} key, useful for developing collections of pre-defined
        key-value pairs for insertion into the optional parameter list. For example,
\begin{Verbatim}[xleftmargin=\amtIndent]
\def\myFavFive{%
    bordercolor={1 0 0},bgcolor={0 1 0},
    textcolor={1 0 0},align={right},uptxt={Push Me}}
\end{Verbatim}
Later, a button can be created using these preset values:
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\ui{presets=\myFavFive,
    js={app.alert("AcroTeX rocks!")}}]{pb1}{}{11bp}
\end{Verbatim}

    \item[] The \textsf{xkeyval} KVP system is described in \mlNameref{useui}.

\end{enumerate}
\redpoint The first (optional) parameter is read in first, but only after ``sanitizing'' certain
characters that have special meaning to {\LaTeX}, these are \texttt{\string~}, \texttt{\#},
and \texttt{\&}; each of these may appear as part of a URL, or may appear in JavaScript code.
Within the first parameter, these three character can be used freely, without escaping them.

\subsection{Button Fields}

Buttons are form elements that the user interacts with using only a
mouse. There are three types of buttons: push buttons, check boxes
and radio buttons.

\subsubsection{Push Buttons}

The push button is a button field that has no
value, it is neither on nor off. Generally, push buttons are used
to initiate some action, such as JavaScript action.

\settowidth{\aebdimen}{\cs{pushButton[\#1]\darg{\#2}\darg{\#3}\darg{\#4}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\pushButton[#1]{#2}{#3}{#4}
\end{dCmd}

\PD
\begin{enumerate}
\item[\texttt{\#1}:] optional, used to enter any modification of appearance/actions
\item[\texttt{\#2}:] the title of the button field
\item[\texttt{\#3}:] the width of the bounding rectangle
\item[\texttt{\#4}:] the height of the bounding rectangle
\end{enumerate}

\paragraph*{Default Appearance:} The default appearance of
a push button is determined by the following:
\begin{Verbatim}[xleftmargin=\amtIndent]
\W{1}\S{B}\F{\FPrint}\BC{0 0 0}
\H{P}\BG{.7529 .7529 .7529}
\end{Verbatim}

\paragraph*{Key Variables:} The first (optional) parameter can be
used to modify the default appearance of a button field and to add
some actions. Following is a list of the variables used within the
brackets of this optional argument for the pushbutton: \tableCs{Ff},
\tableCs{F}, \Cs{H}, \Cs{TU}, \Cs{W}, \Cs{S}, \Cs{R}, \Cs{BC},
\Cs{BG}, \Cs{CA}, \Cs{RC}, \Cs{AC}, \Cs{mkIns}, \Cs{textFont},
\Cs{textSize}, \Cs{textColor}, \Cs{A}, \Cs{AA} and \Cs{rawPDF}.
See the \hyperlink{kv}{Support Key Variables} table for
descriptions and notes on each of these variables.

\handpoint If the \textit{width} argument (\texttt{\#3}) is left
empty, the {\LaTeX} code attempts to determine the appropriate
width based on the width of the text given by \Cs{CA}, \Cs{RC} and
\Cs{AC}. See \textbf{Example~2}, below.

\paragraph*{Global Modification:} \cs{everyPushButton\darg{\anglemeta{KV-pairs}}}

\Example This example resets all forms in this document:
    \pushButton[\CA{Push}\AC{Me}\RC{Reset}\A{/S/ResetForm}]{myButton}{36bp}{12bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Push}\AC{Me}\RC{Reset}\A{/S/ResetForm}]
    {myButton}{36bp}{12bp}
\end{Verbatim}

\Example Button with empty \textit{width} argument:
    \pushButton[\CA{Push}\AC{Me}\RC{Reset}\A{/S/ResetForm}]{myButton}{}{12bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Push}\AC{Me}\RC{Reset}\A{/S/ResetForm}]
    {myButton}{}{12bp}
\end{Verbatim}

\subsubsection{Check Boxes}\label{CheckBoxes}

A check box is a type of button that has one of two values,
``off'' or ``on''.  The value of the field when the field is
``off'' is \texttt{Off}; the value of the ``on'' state can be
defined by the user.

\settowidth{\aebdimen}{\cs{checkBox[\#1]\darg{\#2}\darg{\#3}\darg{\#4}\darg{\#5}}}
\begin{dCmd}{\aebdimen+2\fboxsep+2\fboxrule}
\checkBox[#1]{#2}{#3}{#4}{#5}
\end{dCmd}

\PD
\begin{enumerate}
\item[\texttt{\#1}:] optional, used to enter any modification of appearance/actions
\item[\texttt{\#2}:] the title of the check box button
\item[\texttt{\#3}:] the width of the bounding rectangle
\item[\texttt{\#4}:] the height of the bounding rectangle
\item[\texttt{\#5}:] the name of the ``on'' state (the export value)
\end{enumerate}

\paragraph*{Default Appearance:} The default appearance of
a standard check box is determined by the following:
\begin{Verbatim}[xleftmargin=\amtIndent]
\W{1}\S{S}\BC{0 0 0}\F{\FPrint}
\end{Verbatim}

\paragraph*{Key Variables:} The first (optional) parameter can be
used to modify the default appearance of a check box and to add
some actions. Following is a list of the variables used within the
brackets of this optional argument for the check box: \tableCs{Ff},
\tableCs{F}, \Cs{TU}, \Cs{W}, \Cs{S}, \Cs{MK}, \Cs{DA}, \Cs{AP},
\Cs{AS}, \Cs{R}, \Cs{textFont}, \Cs{textSize}, \Cs{textColor},
\Cs{DV}, \Cs{V}, \Cs{A}, \Cs{AA} and \Cs{rawPDF}. See the
\hyperlink{kv}{Supported Key Variables} table for descriptions and
notes on each of these variables.

\paragraph*{Global Modification:} \cs{everyCheckBox\darg{\anglemeta{KV-pairs}}}

\Example  Are you married? Yes: \checkBox[\symbolchoice{circle}]{myCheck}{10bp}{10bp}{On}
\begin{Verbatim}[xleftmargin=\amtIndent]
\checkBox[\symbolchoice{circle}]{myCheck}{10bp}{10bp}{On}
\end{Verbatim}
\noindent In the example, the appearance of this check box was
modified through the global modification scheme. The following
command appears in the preamble of this document:

\subsubsection{Radio Buttons}\label{RadioButtons}

A radio button field is similar to a check box, but is meant to be
used in unison with one or more additional radio buttons.

\item[\texttt{\#2}:] the title of the radio button
\item[\texttt{\#3}:] the width of the bounding rectangle
\item[\texttt{\#4}:] the height of the bounding rectangle
\item[\texttt{\#5}:] the name of the ``on'' state (the export value)
\end{enumerate}
\redpoint A collection of radio buttons meant to be used in unison
need to all have the same title (parameter~\texttt{\#2}) but
different export values (parameter~\texttt{\#5)}.

\paragraph*{Default Appearance:} The default appearance of
a standard radio button is determined by the following:
\begin{Verbatim}[xleftmargin=\amtIndent]
\W{1}\S{S}\BC{0 0 0}\F{\FPrint}

\Cs{AS}, \Cs{R}, \Cs{textFont}, \Cs{textSize}, \Cs{textColor},
\Cs{DV}, \Cs{V}, \Cs{A}, \Cs{AA} and \Cs{rawPDF}. See the
\hyperlink{kv}{Supported Key Variables} table for descriptions and
notes on each of these variables.

%\redpoint \cs{Ff} \textbf{Field flags.}  The values
%{250606175054} appropriate to a radio button are \Cs{FfNoToggleToOff} (if set,
%one radio button must be set at all times) and
%\Cs{FfRadiosInUnison} (if set, radio buttons with the same value
%will be turned on or off in unison, PDF 1.5).

\paragraph*{Global Modification:} \cs{everyRadioButton\darg{\anglemeta{KV-pairs}}}

\Example What is your gender? Male: \radioButton{myRadio}{10bp}{10bp}{Male} %[\Ff{\FfNoToggleToOff}]
    Female: \radioButton{myRadio}{10bp}{10bp}{Female}
    Neither: \radioButton[\A{\JS{app.alert("You can't be 'neither'! I'm resetting the field, guess again!");\r

\subsection{Choice Fields}

A choice field is a list of text items, one or more of which can
be selected by the user.

\subsubsection{List Boxes}

A scrollable list box is a type of choice field in which several
of the choices are visible in a rectangle.  A scroll bar becomes
available if any of the items in the list are not visible in the
rectangle provided.

\settowidth{\aebdimen}{\cs{listBox[\#1]\darg{\#2}\darg{\#3}\darg{\#4}\darg{\#5}}}

\item[\texttt{\#3}:] the width of the bounding rectangle
\item[\texttt{\#4}:] the height of the bounding rectangle
\item[\texttt{\#5}:] an array of appearance/values of list.
\end{enumerate}
\newtopic The fifth parameter needs more explanation. The value of this
parameter which defines the items in the list---their appearance
text and their export values---take two forms:
\begin{questions}
    \item An array of arrays:
\begin{Verbatim}[xleftmargin=\amtIndent]
[(v1)(item1)][(v2)(item2)]...[(vn)(itemn)]
\end{Verbatim}
        The first entry in the two member array is the export value of the item, the second
        is the appearance text of that item.
    \item An array of strings:
\begin{Verbatim}[xleftmargin=\amtIndent]
(item1)(item2)...(itemn)
\end{Verbatim}
        In this case, the export value is the same as the appearance text.
\end{questions}

\paragraph*{Default Appearance:} The default appearance of
a standard list box is determined by the following:
\begin{Verbatim}[xleftmargin=\amtIndent]
\W{1}\S{I}\F{\FPrint}\BC{0 0 0}
\end{Verbatim}

\paragraph*{Key Variables:} The first (optional) parameter can be

\subsection{Signature Fields}\label{sigfields}

A signature field is a field that can be digitally signed.

\settowidth{\aebdimen}{\cs{sigField[\#1]\darg{\#2}\darg{\#3}\darg{\#4}}}
\begin{dCmd}{\aebdimen+2\fboxsep+2\fboxrule}
\sigField[#1]{#2}{#3}{#4}
\end{dCmd}

\PD
\begin{enumerate}
\item[\texttt{\#1}:] optional, used to enter any modification of appearance/actions
\item[\texttt{\#2}:] the title of the signature field
\item[\texttt{\#3}:] the width of the bounding rectangle
\item[\texttt{\#4}:] the height of the bounding rectangle
\end{enumerate}

\paragraph*{Default Appearance:} The default appearance of
a standard signature field is determined by the following:
\begin{Verbatim}[xleftmargin=\amtIndent]
\F{\FPrint}\BC{}\BG{}\W{1}\S{S}
\end{Verbatim}

\paragraph*{Key Variables:} The first (optional) parameter can be
used to modify the default appearance of a signature field and to add some
actions. Following is a list of the variables used within the
brackets of this optional argument for the signature field:
\tableCs{F}, \Cs{TU}, \Cs{W}, \Cs{S}, \Cs{R}, \Cs{Lock},
\Cs{BC}, \Cs{BG}, \Cs{mkIns}, \Cs{textFont}, \Cs{textSize},
\Cs{textColor}, \Cs{DV}, \Cs{A}, \Cs{AA} and \Cs{rawPDF}.
See the \hyperlink{kv}{Supported Key Variables} table for
descriptions and notes on each of these variables.

\paragraph*{Global Modification:} \cs{everySigField\darg{\anglemeta{KV-pairs}}}

\Example Sign here:\\[3pt]
    \sigField[\BC{0 0 0}]{mySig}{2in}{4\baselineskip}\hfill
    \begin{minipage}{\linewidth-2in-10bp}
    \verb!\sigField[\BC{0 0 0}]!\\
    \verb!  {mySig}{2in}{4\baselineskip}!
    \end{minipage}

\newtopic To sign this field, use the \app{Acrobat} user interface, or use the
package \textsf{aeb\_pro}, and the following \texttt{docassembly} code:

\begin{Verbatim}[xleftmargin=\amtIndent]
\begin{docassembly}
\signInfo{
    cSigFieldName: "mySig", ohandler: security.PPKLiteHandler,
    cert: "D_P_Story.pfx", password: "dps017",
    oInfo: { location: "Niceville, FL",
      reason: "I am approving this document",
      contactInfo: "dpstory@acrotex.net",
      appearance: "My Signature" }
};
\signatureSign
\end{docassembly}
\end{Verbatim}

\begin{itemize}
  \item \texttt{cSigFieldName} is the name of the field to be signed.
  \item \texttt{ohandler} is the name of the security handler to be
    used to sign the field, usually, this is \texttt{security.PPKLiteHandler};
    \texttt{security.PPKLiteHandler} is used if \texttt{ohandler} is not listed in the property list.
  \item \texttt{cert} is the name of the Digital ID certificate file to be used.
  The extension for this file is \texttt{.pfx} (Windows) and \texttt{.p12} (Mac OS).
  These files reside in the folder,
\begin{Verbatim}[xleftmargin=\amtIndent]
app.getPath( {cCategory:"user"})/Security
\end{Verbatim}
However, just enter the file name, such as \texttt{cert:} \texttt{"D\_P\_Story.pfx"}.
\item \texttt{password}: The Digital ID requires a password to access and to use.
For example: \texttt{password:} \texttt{"dps017"}.
\item \texttt{oInfo} is a JavaScript object with various properties to be filled in,
\texttt{location}, \texttt{reason}, \texttt{contactInfo}, and \texttt{appearance}.
The \texttt{appearance} is important, through it, you can choose a particular appearance
for the digital signature, including a custom signature that you've created. In the example
above, we have \texttt{appearance: "My Signature"}.  \texttt{My Signature} is the name I've
given a particular digital ID of mine. If the \texttt{appearance} property is not
included in \texttt{oInfo}, \app{Acrobat} will use the one named \texttt{"Standard Text"}.
\end{itemize}

\Important Additional information on signatures can be found
at the \mlhref{http://www.adobe.com/go/acrobat_developer}{\mbox{\app{Acrobat}} Developer Center};
or go to the \href{http://www.adobe.com/go/acrobat_security}{Security page};
in particular, see the document \textit{Digital Signature User Guide for \app{Acrobat} 9.0
and Adobe Reader 9.0}. Other comments on the topic of signature fields:
\begin{itemize}
\item The open key \cs{textSize} is recognized, but is change to 0.
\item The Signed tab of the Digital Signatures Properties dialog box, lists
an entry titled ``This script executes when the field is signed.'' This
JavaScript is implemented through the format script of the \texttt{AA} key.
Thus,
\begin{Verbatim}[xleftmargin=\amtIndent]
\AA{\AAFormat{console.println("Signed!");}}
\end{Verbatim}
places message in the console when the field is signed.

\item The \cs{Lock} key can be used to lock various fields when the document
is signed.
\begin{Verbatim}[xleftmargin=\amtIndent,numbers=left]
\Lock{/Action/All}
\Lock{/Action/Include/Fields [(field1)(field2)...]}
\Lock{/Action/Exclude/Fields [(field1)(field2)...]}
\end{Verbatim}
\begin{itemize}
    \item In (1), all fields are locked when the signature field is signed.
    \item In (2), only the listed fields are locked when the signature
        field is signed.
    \item In (3), all fields, except the ones listed, are locked when the
        signature field is signed.
\end{itemize}
The \texttt{/Fields} key is required when the action is either \texttt{/Include} or \texttt{/Exclude}.
\end{itemize}

\section{Link Annotations}\label{linkAnnots}

The \textsf{eforms} package has several link commands that are
sufficiently general that they can be given arbitrary appearances,
and can perform a wide range of actions.

The borders of the link commands can be controlled through optional
parameter, their default appearance follow the same pattern of
hyperref: If the \texttt{colorlinks} option is used (in
\textsf{hyperref}) then the border is invisible by default;
otherwise, there is a visible border.

When the \texttt{colorlinks} option is chosen (in hyperref), the
link text is colored using the command \cs{defaultlinkcolor}, this
is a named color. \cs{defaultlinkcolor} has a definition of
\begin{Verbatim}[xleftmargin=\amtIndent]
\newcommand{\defaultlinkcolor}{\@linkcolor}
\end{Verbatim}
\noindent where \cs{@linkcolor} is a command defined in
\textsf{hyperref}, and is defined to be \texttt{red}. This can be
redefined as desired.\footnote{The {\Web} package redefines
\cs{@linkcolor} to be a flavor of green.}

The first link command is a general link for text, or any
{\LaTeX} content. It is used, for example, by the \textsf{aeb\_mlink}
package to create multiple-line links.

\settowidth{\aebdimen}{\cs{setLinkText[\meta{options}]\darg{\meta{link\_text}}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\setLink[!meta(options)]{!meta(link_text)}
!grayV(\setLinkText[!meta(options)]{!meta(link_text)})
\end{dCmd}
\newtopic Both link commands are the same, the use of the second one, \cs{setLinkText} (grayed out), is
discouraged in favor of the use of \cs{setLink}.

\PD The command has two arguments, the first is optional. The first
parameter takes key-value pairs to change appearance and define
actions. The default appearance of this link is \verb!\S{S}\Border{0 0 0}!,
an invisible yet solid border line. (The visibility of the border is
actually controlled by the \texttt{colorlinks} option of
\textsf{hyperref}, as explained above.) The second parameter is the
link text. This argument does not have to be text, it can be
anything that takes up space, such as a graphic or \cs{parbox}.

\section{Actions}\label{Actions}

A form field may simply gather data from the user; additionally,
it may perform one or more \textit{actions}. Actions include
execute JavaScript code, going to a particular page in a document,
open a file, execute a menu item, reset a form, play media or a
sound, and so on.  Beginning with \app{Acrobat}~5.0, most actions can be
performed using JavaScript methods.

An action is initiated by a \textit{trigger}, a field may have
many actions, each with a separate trigger. The different triggers
are discussed in \nameref{triggers}, and the various types of
actions available are covered in the
section~\nameref{actiontypes}.

\subsection{Trigger Events}\label{triggers}

Event actions are initiated by \textit{triggers}. For fields,
there are ten different triggers.
\begin{questions}
    \item \textbf{Mouse Enter:} The event is triggered when mouse
    enters the region defined by the bounding rectangle. The
    \cs{AAMouseEnter} key is used within the argument of \Cs{AA}
    to define a mouse enter event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{\AAMouseEnter{%
    \JS{app.alert("You've entered my text field, get out!")}}}]
    {myText}{1.5in}{12bp}
\end{Verbatim}
    \item \textbf{Mouse Exit:} The event is triggered when mouse
    exits the region defined by the bounding rectangle. The
    \cs{AAMouseExit} key is used within the argument \Cs{AA} to
    define a mouse exit event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{\AAMouseExit{%
    \JS{app.alert("You've exited my domain, never return!")}}}]
    {myText}{1.5in}{12bp}
\end{Verbatim}
    \item \textbf{Mouse Down:} The event is triggered when the
    (left) mouse button is pushed down while the mouse is within the
    bounding rectangle of the field. The \cs{AAMouseDown} key is
    used within the argument of \Cs{AA} to define a mouse down
    event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\AA{\AAMouseDown{\JS{app.alert("Mouse Down!")}}}]
    {myButton}{30bp}{12bp}
\end{Verbatim}
    \item \textbf{Mouse Up:} The event is triggered when the
    (left) mouse  button is released while the mouse is within the
    bounding rectangle of the field. The \Cs{A} key (or
    \cs{AAMouseUp} key is used within the argument of \Cs{AA}) is
    used to define a mouse up event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\A{\JS{app.alert("Mouse Up!")}}]
    {myButton}{30bp}{12bp}
\end{Verbatim}
The same code can be performed as follows:
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\AA{\AAMouseUp{\JS{app.alert("Mouse Up!")}}}]
    {myButton}{30bp}{12bp}
\end{Verbatim}
When both types of mouse up actions are defined for the same
field, the one defined by \Cs{A} is the one that is executed.

    \item \textbf{On Focus:} The event is triggered when the field
    comes into focus (either by tabbing from another field, or
    clicking the mouse within the bounding rectangle. The \cs{AAOnFocus}
    key is used within the argument of \Cs{AA} to define an `on focus'
    event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{\AAOnFocus{\JS{%
    app.alert("Please enter some data!")}}}]
{myText}{1.5in}{12bp}
\end{Verbatim}

    \item \textbf{On Blur:} The event is triggered when the field
    loses focus (either by tabbing to another field, by clicking
    somewhere outside the field, or (in the case of a text field,
    for example) pressing the \texttt{Enter} button. The \cs{AAOnBlur}
    key is used within the argument of \Cs{AA} to define an `on blur'
    event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{\AAOnBlur{%
    \JS{app.alert("Thanks for the data, I think!")}}}]
{myText}{1.5in}{12bp}
\end{Verbatim}

    \item \textbf{Format:}\label{format} The format event is the event that
    occurs when text is entered into a text or combo box; during
    this event, optionally defined JavaScript code is executed to
    format the appearance of the text within the field. The
    \cs{AAFormat} key is used within the argument of \Cs{AA} to
    define a format event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{%
    \AAKeystroke{AFNumber_Keystroke(2,0,1,0,"\\u0024",true);}
    \AAFormat{AFNumber_Format(2,0,1,0,"\\u0024",true);}}]
{myText}{1.5in}{12bp}
\end{Verbatim}
The above example creates a text field which will accept only a
number into it and which will format the number into U.S.
currency.

    \item \textbf{Keystroke:} This keystroke event is the event
    that occurs when individual keystroke is entered into a choice
    field (list or combo) or a text field; during this event,
    optionally defined JavaScript can be used to process the
    keystroke. The \cs{AAKeystroke} key is used within the
    argument of \Cs{AA} to define a keystroke event; see the format
    example above.

    \item \textbf{Validate:} The validate event is an event for
    which JavaScript code can be defined to validate the data that
    has been entered (text and combo fields only). The
    \cs{AAVali\-date} key is used within the argument of \Cs{AA} to
    define a validate event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{%
  \AAKeystroke{AFNumber_Keystroke(2,0,1,0,"\\u0024",true);}
  \AAFormat{AFNumber_Format(2,0,1,0,"\\u0024",true);}
  \AAValidate{%
    if (event.value > 1000 || event.value < -1000) {\r\t
      app.alert("Invalid value, rejecting your value!");\r\t
      event.rc = false;\r
    }}
}]{myText}{1.5in}{12bp}
\end{Verbatim}

    \item \textbf{Calculate:} The calculate event is an event for
    which JavaScript code can be defined to make automatic
    calculations based on entries of one or more fields (text and
    combo fields only). The \cs{AACalculate} key is used within the
    argument of \Cs{AA} to define a calculate event:
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{%
  \AAKeystroke{AFNumber_Keystroke(2,0,1,0,"\\u0024",true);}
  \AAFormat{AFNumber_Format(2,0,1,0,"\\u0024",true);}
  \AACalculate{AFSimple_Calculate("SUM",new Array("Prices"));}
}]{myText}{1.5in}{12bp}
\end{Verbatim}
    \item \textbf{PageOpen:} (The \textbf{PO} key, Table 8.10, PDF 1.5) An
        action to be performed when the page containing the annotation
        is opened (for example, when the user navigates to it from the
        next or previous page or by means of a link annotation or outline
        item). The action is executed after the page's open action. The
        \cs{AAPageOpen} key is used within the argument of \Cs{AA} to
        define an annotation page open event:
    \item \textbf{PageClose:} (The \textbf{PC} key, Table 8.10, PDF 1.5) An
        action to be performed when the page containing the annotation
        is closed (for example, when the user navigates to the next or
        previous page, or follows a link annotation or outline item).
        The action is executed before the page's close action.
        \cs{AAPageClose} key is used within the argument of \Cs{AA} to
        define an annotation page close event.
    \item \textbf{PageVisible:} (The \textbf{PV} key, Table 8.10,
        PDF 1.5) An action to be performed when the page containing the
        annotation becomes visible in the viewer application's user
        interface. \cs{AAPageVisible} key is used within the
        argument of \Cs{AA} to define an annotation page visible event.
    \item \textbf{PageInvisible:} (The \textbf{PI} key, Table 8.10,
        PDF 1.5) An action to be performed when the page containing
        the annotation is no longer visible in the viewer
        application's user interface. \cs{AAPageInvisible} key is used
        within the argument of \Cs{AA} to define an annotation page
        invisible event.
    \item[] Below is a simple example of usage. The actions write to the console.
\begin{Verbatim}[xleftmargin=\amtIndent]
\textField[\AA{%
    \AAPageOpen{console.println("Page \thepage: PO");}
    \AAPageClose{console.println("Page \thepage: PC");}
    \AAPageVisible{console.println("Page \thepage: PV");}
    \AAPageInvisible{console.println("Page \thepage: PI");}
    }]{tf\thepage}{2in}{11bp}
}
\end{Verbatim}
\end{questions}
Additional examples appear in the file \texttt{eqforms.tex}.

\subsection{Action Types}\label{actiontypes}

The following is only a partial listing of the action types, as
given in \textsf{Table~8.36} of the \textit{PDF
Reference}~\cite{tech:PDFRef}. The entire list and the details of
usage can be obtained from the \textit{PDF Reference}.

\begin{center}
\begin{tabular}{>{\ttfamily\small}l>{\small}l}
\multicolumn{1}{>{\bfseries}l}{Action Type} & \multicolumn{1}{>{\bfseries}l}{Description}\\\hline
GoTo & Go to a destination in the current document\\
GoToR& Go to a destination in another document\\
Launch& Launch an application, usually to open a file\\
URI&Resolve a uniform resource identifier\\
Named & Execute an action predefined by the viewer\\
SubmitForm & Send data to a uniform resource locator\\
JavaScript & Execute a JavaScript script (PDF 1.3)\\
\end{tabular}
\end{center}
Examples of each type of action follow.

\redpoint{\texttt{GoTo}:} Go to a (named or explicit) destination
within the current document. In this example, we `go to' the named
destination \texttt{toc.1}, which references the table of contents
pages. This button goes to a \textit{named destination}:
\pushButton[\CA{Go}\AC{Now!}\RC{to TOC}\A{/S/GoTo/D(toc.1)}]{myButton1}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Now!}\RC{to TOC}
    \A{/S/GoTo/D(toc.1)}]{myButton1}{}{10bp}
\end{Verbatim}
\noindent For a named destination, the value of the \texttt{/D} key is a string, \texttt{(toc.1)}
in the above example, that specifies the destination name.

The following is an example of an \textit{explicit destination}:
\pushButton[\CA{Go}\AC{Now!}\RC{to Page 3}\A{/S/GoTo/D[{Page3}/Fit]}]{myButton1}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Now!}\RC{to Page 3}
\A{/S/GoTo/D[{Page3}/Fit]}]{myButton1}{}{10bp}
\end{Verbatim}
\noindent The value of the destination key \texttt{/D} is an array
referencing a page number (\verb+{Page3}+) and a view
(\texttt{/Fit}).

For a \texttt{GoTo} action, the first entry in the destination
array, \texttt{\char123Page3\char125}, is an indirect reference to
a page, the notation \texttt{\char123Page3\char125} is understood
by the \textsf{distiller}. For  \textsf{dvipdfm}, use the \texttt{@page}
primitive:
\begin{Verbatim}[xleftmargin=\amtIndent]
\makeatletter\def\Page#1{@page#1}\makeatother
\pushButton[\CA{Go}\AC{Now!}\RC{to Page 3}
\A{/S/GoTo/D[\Page3/Fit]}]{myButton1}{}{10bp}
\end{Verbatim}
\noindent \textsf{pdftex} has no mechanism for inserting
indirect page references.

See section~8.5.3, `Go-To Actions', of the \textit{PDF
Reference}~\cite{tech:PDFRef} for details of the syntax of
\texttt{GoTo}, and section~8.2.1 for documentation on explicit and
named destinations.

\redpoint{\texttt{GoToR}:} Go to a (named or explicit) destination in a remote
document. In this example, we `go to a remote' destination, a
\textit{named destination} in another document.
\pushButton[\CA{Go}\AC{Now!}\RC{to TOC}\A{/S/GoToR/F(webeqtst.pdf)/D(webtoc)}]{myButton2}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Now!}\RC{to TOC}
    \pushButton[\CA{Go}\AC{Now!}\RC{to TOC}
    \A{/S/GoToR/F(webeqtst.pdf)/D(webtoc)]{myButton2}{}{10bp}
\end{Verbatim}
\noindent This example illustrates an \textit{explicit destination};
the following button jumps to page~3 in another document:
\pushButton[\CA{Go}\AC{Now!}\RC{to Page 3}\A{/S/GoToR/F(webeqtst.pdf)/D[2/Fit]}]{myButton2}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Now!}\RC{to Page 3}
\A{/S/GoToR/F(webeqtst.pdf)/D[2/Fit]}]{myButton2}{}{10bp}
\end{Verbatim}
\noindent The value of the destination key \texttt{/D} is an array
referencing a page number and a view (\texttt{/Fit}).

For an \textit{explicit destination}, the \textit{PDF
Reference}~\cite{tech:PDFRef} specifies that the first entry in
the destination array should be a page number (as contrasted with
an indirect reference to a page number, for the case of
\texttt{GoTo}). The destination, \texttt{/D[2/Fit]} would correctly work
for \textsf{distiller}, \textsf{dvipdfm} and \textsf{pdftex}.

See section~8.5.3, `Remote Go-To Actions', of the \textit{PDF
Reference}~\cite{tech:PDFRef} for details of the syntax of
\texttt{GoToR}, and section~8.2.1 for documentation on explicit
and named destinations.

\redpoint{\texttt{Launch}:} Launch an application (`Open a file').
In this example, we open a {\TeX} file using the application
associated with the \texttt{.tex} extension:
\pushButton[\CA{Go}\AC{TeX Doc!}\RC{to a}\A{/S/Launch/F(webeqtst.tex)}]{myButton3}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Now!}\RC{to TOC}
\A{/S/Launch/F(webeqtst.tex)}]{myButton3}{}{10bp}
\end{Verbatim}
\noindent See section~8.5.3, `Launch Actions', of the \textit{PDF Reference}~\cite{tech:PDFRef}
for details of the syntax.

\redpoint{\texttt{URI}:} Open a web link. In this example, we go to the Adobe web site:
\pushButton[\CA{Go}\AC{Adobe!}\RC{To}\A{/S/URI/URI(http://www.adobe.com/)}]{myButton4}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Adobe!}\RC{To}
\A{/S/URI/URI(http://www.adobe.com/)}]{myButton4}{}{10bp}
\end{Verbatim}
\noindent See section~8.5.3, `URI Actions', of the \textit{PDF
Reference}~\cite{tech:PDFRef} for details of the syntax.

\app{Acrobat} (Adobe Reader) also support open parameters, using these key-value pairs,
we can go to a specific page in a PDF on the web, and even search for words, for example
\pushButton[\CA{Go & Search}\A{/S/URI/URI(http://www.math.uakron.edu/~dpstory/acrotex/aeb_man.pdf#page=8&search=AcroTeX web exerquiz)}]{myButton4a}{}{10bp}
opens the AeB Manual on the Internet, goes to page 8, and searches for the words
AcroTeX, web, and exerquiz.
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go & Search}
\A{/S/URI/URI(http://www.math.uakron.edu/~dpstory/
    acrotex/aeb_man.pdf#page=8&search=AcroTeX web exerquiz)}]
    {myButton4a}{}{10bp}
\end{Verbatim}
The same can be accomplished using \cs{setLink}.

\redpoint{\texttt{Named}:} Execute a `named' action (i.e., a menu
item). Named actions listed in the \textit{PDF Reference} are
\texttt{NextPage}, \texttt{PrevPage}, \texttt{FirstPage} and
\texttt{LastPage}. A complete list of named actions can be
obtained by executing the code \texttt{app.listMenuItems()} in
the JavaScript console of \app{Acrobat} (Pro).
\pushButton[\CA{Go}\AC{Previous!}\RC{To}\A{/S/Named/N/PrevPage}]{myButton5}{}{10bp}
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Go}\AC{Previous!}\RC{To}
\A{/S/Named/N/PrevPage}]{myButton5}{}{10bp}
\end{Verbatim}
\newtopic See section~8.5.3, `Named Actions,' of the \textit{PDF
Reference}~\cite{tech:PDFRef} for details of the syntax. The named
actions listed in the PDF Reference are \texttt{NextPage},
\texttt{PrevPage}, \texttt{FirstPage}, and \texttt{LastPage}.

In theory, any menu item can be executed as a named actions; there
are several factors to be taken into consideration: (1) Not all menu
items available to \app{Acrobat} are listed on the menu bar of Adobe
Reader, when choosing a name event to use, you should decide if the
application executing the named action supports that action; (2) In
recent versions, starting with version 7, there have been security
restrictions on the execution of menu items, the so-called ``white
list.'' Only named actions listed on the white list are allowed to
execute.  The white list for version 8.0 is

\section{JavaScript}

\app{Acrobat} JavaScript is the cross-platform scripting language of the
\app{Acrobat} suite of products. For \app{Acrobat} 5.0 or later, \app{Acrobat}
JavaScript based on JavaScript version 1.5 of ISO-16262 (formerly
known as ECMAScript), and adds extensions to the core language to
manipulate \app{Acrobat} forms, pages, documents, and even the viewer
application.

Web-based references to core JavaScript are the \textit{Core
JavaScript Guide}~\cite{tech:NetscapeJSGuide} and the \textit{Core
JavaScript Reference}~\cite{tech:NetscapeJSReference}. For \app{Acrobat}
JavaScript, we refer you to the \textit{Developing \app{Acrobat}
Applications using JavaScript}~\cite{tech:AcroJSGuide} and the
\textit{JavaScript for \app{Acrobat} API Reference}~\cite{tech:AcroJSRef}.

\subsection{Support of JavaScript}

The {\cAcroEB} has extensive support for JavaScript, not only for
JavaScript executed in response to a field trigger, but for
document level and open page actions as well.  As the topic of this
document is \textsf{eForm} support, the reader is referred to the
documentation in the \textsf{insdljs} package, which is distributed with
the {\cAcroB}.

\subsubsection{The Convenience Command
    \texorpdfstring{\protect\cs{JS}}{\CMD{JS}}}\label{convienceJS}

The syntax for writing JavaScript actions is
\begin{Verbatim}[xleftmargin=\amtIndent,commandchars=!~@]
\pushButton[\A{/S/JavaScript/JS(!anglemeta~script@)}]
    {jsEx}{22bp}{11bp}
\end{Verbatim}
Notice the code is enclosed in matching parentheses.
\hyperlink{JSdefined}{As noted earlier}, {\cAcroT} defines the command
\cs{JS} as a convenience for this very common actions; the above example
becomes:
\begin{Verbatim}[xleftmargin=\amtIndent,commandchars=!()]
\pushButton[\A{\JS{!anglemeta(script)}}]{jsEx}{22bp}{11bp}
\end{Verbatim}
\noindent The code is now enclosed in matching braces.

\subsubsection{Inserting Simple JavaScript}

Actions are introduced into a field command through its optional
first parameter. JavaScript actions, in particular, can be
inserted by a mouse up\footnote{Other types of possible actions
are discussed and illustrated in \Nameref{Actions}.} action, for
example, using the \Cs{A} and \hyperref[convienceJS]{\cs{JS}}
commands.

The ``environment'' for entering JavaScript is not a verbatim
environment: `\verb+\+' is the usual {\TeX} escape character and
expandable commands are expanded; active characters are expanded
(which is usually not what you want); and primitive commands
appear verbatim (so you can use, for example, `\verb+{+' and
`\verb+}+). Within the optional argument, the macro
\cs{makeJSspecials}, which can be redefined, is expanded; the
macro makes several special definitions: (1) it defines \verb+\\+ to be
`\verb+\\+'; (2) defines \cs{r} to be the JavaScript escape
sequence for new line; and (3) defines \cs{t} to be the JavaScript
escape sequence for tab.

\Example\label{ex:formattedBtn} \pushButton[\CA{Sum}\A{\JS{%
        var n = app.response("Enter a positive integer", "Summing the first \\"n\\" integers");\r
        if ( n != null ) {\r\t
            var sum = 0;\r\t
            for ( var i=1; i <= n; i++ ) {\r\t\t
                sum += i;\r\t
            }\r
        app.alert("The sum of the first n = " + n + " integers is " + sum + ".", 3);
        }
    }}]{jsSum}{22bp}{11bp}

\smallskip\noindent The verbatim listing for this button is
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\CA{Sum}\A{\JS{%
    var n = app.response("Enter a positive integer",
        "Summing the first \\"n\\" integers");\r
    if ( n != null ) {\r\t
        var sum = 0;\r\t
        for ( var i=1; i <= n; i++ ) {\r\t\t
            sum += i;\r\t
        }\r
    app.alert("The sum of the first n = " + n
        + " integers is " + sum + ".", 3);
    }
}}]{jsSum}{22bp}{11bp}
\end{Verbatim}

\paragraph*{Code Comments.} Within the JavaScript string, we want
literal double quotes \texttt{"}, to avoid \texttt{"} being
interpreted as the end of the string (or the beginning of a string)
we have to double escape the double quotes, as in \verb+\\"+.  (This
is not necessary when entering code in the JavaScript editor if you
have the \app{Acrobat} application.)  I try to write JavaScript that I can easily
read, edit, and debug in the JavaScript editor (available in
the full \app{Acrobat} application); for this reason, I've added in new
lines and tabbing (\cs{r} and \cs{t}). Many people, however, have
only the Adobe Reader and cannot see their code to debug it; in this
case, the formatting is really not needed.

%\newtopic Consider the following code
%\begin{Verbatim}[xleftmargin=\amtIndent]
%    \pushButton[\A{\JS{var x = "~"}}]{jsTilde}{22bp}{11bp}
%\end{Verbatim}
%\noindent In {\LaTeX}, `\texttt{\~}' is an active character. JavaScript above appears
%within the JavaScript editor as
%\begin{Verbatim}[xleftmargin=\amtIndent]
%var x = "protect unhbox voidb@x penalty @M  {}"
%\end{Verbatim}
%\noindent Not good! Using `\verb+\~+' or `\verb+\\~+ fairs no better.
%The work around is to use \verb!\string~!.
%\begin{Verbatim}[xleftmargin=\amtIndent]
%    \pushButton[\A{\JS{var x = "\jslit~"}}]{jsTilde}{22bp}{11bp}
%\end{Verbatim}

\newtopic Needless to say, the following sample will not compile because we do not have
matching braces.
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\A{\JS{var x = "{"}}]{jsBrace}{22bp}{11bp}
\end{Verbatim}
\noindent The work around here is
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\A{\JS{var x = "\jslit\{"}}]{jsBrace}{22bp}{11bp}
\end{Verbatim}

\newtopic In the above work about, the \cs{jslit} command (for JavaScript literal) is used. This command is defined only within the optional arguments of a form field. The definition of \cs{jslit} is \verb!\let\jslit\string!


\subsubsection{Inserting Complex or Lengthy JavaScript}\label{lengthyJS}

For JavaScript that is more complex or lengthy, the
\textsf{insdljs} Package, distributed with the \cAcroB, has the
verbatim \texttt{defineJS} environment. Details and idiosyncracies of this
environment are documented in \Nameref{defineJS}. The
example given in \hyperref[defineJSEx]{Example~\ref*{defineJSEx}} will suffice; the verbatim listing
is reproduced here for convenience.

\redpoint First, we define the JavaScript action and name it
\cs{getComboJS} for the button (prior to defining the field,
possibly in the preamble, or in style files):
\begin{Verbatim}[xleftmargin=\amtIndent]
\begin{defineJS}{\getComboJS}
    var f = this.getField("myCombo");
    var a = f.currentValueIndices;
    if ( a == -1 )
        app.alert("You've typed in \\"" + f.value +"\\".");
    else
        app.alert("Selection: " + f.getItemAt(a, false)
            + " (export value: " + f.getItemAt(a, true)+").");
\end{defineJS}
\end{Verbatim}
\noindent There is no need for the \cs{r} and \cs{t} commands to format the JavaScript;
the environment obeys lines and spaces; contrast this example with \textbf{Example~\ref*{ex:formattedBtn}},
page~\pageref{ex:formattedBtn}.

Now we can define our fields, a combo box (not shown) and button, in
this example. It is the button that uses the JavaScript defined
above.
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\BC{0 .6 0}\CA{Get}\AC{Combo}\RC{Box}
    \A{\JS{\getComboJS}}]{myComboButton}{33bp}{11bp}
\end{Verbatim}
\noindent Within the argument of \cs{JS} we insert the macro
command, \verb!\JS{\getComboJS}!
for our JavaScript defined earlier in the
\texttt{defineJS} environment

%\redpoint The demo file \href{examples/definejs.pdf}{definejs.pdf}
%(source \texttt{definejs.tex}) has additional examples of this
%environment.

\texttt{\href{\urlAcroTeXBlog/?p=875}{aeb\_links.pdf}}, with source attached,
is found on the {\AcroBlog} website.


\subsection{Defining JavaScript Strings with
    \texorpdfstring{\protect\cs{defineJSStr}}{\CMD{defineJSStr}}}

The command \Com{defineJSStr} is used to define JavaScript strings, such as in dialog boxes.
The syntax for this command is
\settowidth{\aebdimen}{\cs{defineJSStr\darg{\cs{\anglemeta{CMD}}}\darg{\anglemeta{JS\_string}}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\defineJSStr{\!anglemeta(CMD)}{!anglemeta(JS_string)}
\end{dCmd}
\PD Where \cs{\anglemeta{CMD}} is a command to be defined by
\cs{defineJSStr}, for example, \cs{myMessage}, and \anglemeta{JS\_string} is
the JavaScript string to be defined as the expansion of the
\cs{\anglemeta{CMD}}.

\CmdDescription \cs{defineJSStr} executes \verb!\xdef#1{"#2"}!, so
the JavaScript is expanded at the time of definition. (Note the
enclosing double quotes) Before the expansion occurs, however, there
are a number of definitions that occur locally:
\begin{itemize}
  \item \cs{uXXXX} is recognized as a unicode escape sequence. So, within the JavaScript string,
  unicode can be entered directly, for example, \cs{u00FC} is the u-umlaut.

  \item Backslash is still the tex escape character, so any commands
  in the JavaScript string get expanded. You can delay the expansion
  by using \cs{protect}. Expansion occurs when the tex compiler
  actually expands \cs{\anglemeta{CMD}}.

  \item \cs{r} (carriage return), \cs{n} (line feed) and, \cs{t}
  (tab) can be used to format the message, as desired.

  \item Use the \cs{cs} command to write a word containing a literal backslash in it;
  for example, to get \cs{LaTeX} to appear in a JavaScript string, you must type \verb!\cs{LaTeX}!
  in the JavaScript string.
  \item The JavaScript string is enclosed in double quotes (\texttt{"}), if you want
  a literal double quote, use \verb!\\"! to get a literal double quote
  to appear in a JavaScript string. For example,
\begin{Verbatim}[xleftmargin=\amtIndent]
\defineJSStr{\myMessage}
    {My name is \\"Stan\\" and I'm \\"the man.\\"}
\end{Verbatim}

  \item The command \cs{jslit} is recognized within the JavaScript string. Using \cs{jslit}
  (short for JavaScript literal), you can insert, for example, unbalanced braces:
\begin{Verbatim}[xleftmargin=\amtIndent]
\defineJSStr{\myMessage}
    {You forgot the left brace \\"\jslit\{\\",
     please insert it.}
\end{Verbatim}
The definition of \cs{jslit} is \verb!\let\jslit\string!.


\end{itemize}

\newtopic The design decision to automatically insert the double
quotes in the definition of the string has its faults. When you want
to break the string to insert dynamic content, you must always be
aware of the definition \verb!\xdef#1{"#2"}! contained with the
definition of \cs{defineJSStr}. To illustrate, we return to an
earlier example presented in \nameref{lengthyJS}, on
page~\pageref*{lengthyJS}.

We begin by defining some JavaScript strings. Note that in each of
these two definitions, the leading and trailing double quote
(\texttt{"}) is missing (these are the ones inserted automatically).
The definitions look a bit strange because we break the string to
insert dynamic content (\texttt{f.value}, \texttt{f.getItemAt(a,
false)}, etc.), then continue on with the string from there.

\begin{Verbatim}[xleftmargin=\amtIndent]
\defineJSStr\myAlerti{You've typed in \\"" + f.value +"\\".}
\defineJSStr\myAlertii{Selection: " + f.getItemAt(a, false)
   + " (export value: " + f.getItemAt(a, true)+").}
\end{Verbatim}

\newtopic We use the \texttt{defineJS} environment, after setting the escape code to \texttt{@}. The \texttt{defineJS}
is a fully verbatim environment, the escape character cannot be changed to \verb!\!, but it
may be changed to another character, such as \texttt{@}.

\begin{Verbatim}[xleftmargin=\amtIndent]
\begin{defineJS}[\catcode`\@=0\relax]{\getComboJS}
var f = this.getField("myCombo");
var a = f.currentValueIndices;
if ( a == -1 )
    app.alert(@myAlerti);
else
    app.alert(@myAlertii);
\end{defineJS}
\end{Verbatim}

\newtopic Then again, the use of \cs{defineJSStr} is not required, it is a convenience for creating
JavaScript strings, especially ones with embedded Unicode. The previous example could have been
done by defining \cs{myAlerti} and \cs{myAlertii} by
\begin{Verbatim}[xleftmargin=\amtIndent]
\newcommand\myAlerti{"You've typed in \\"" + f.value +"\\"."}
\newcommand\myAlertii{"Selection: " + f.getItemAt(a, false)
   + " (export value: " + f.getItemAt(a, true)+")."}
\end{Verbatim}
\noindent Note the \emph{presence} of the leading and trailing double quotes.

\section{The \texttt{useui} option: A User-Friendly Interface}\label{useui}

\def\myFavFive{%
bordercolor={1 0 0},bgcolor={0 1 0},
textcolor={1 0 0},align={right},
uptxt={Push Me}}


To use the ``user-friendly'' interface, the \texttt{useui} option must be taken. The key-value pairs
described below are enclosed as the argument of the special \cs{ui} key.  For example,
\bgroup\obeyspaces\ttfamily%
\settowidth{\aebdimen}{    bordercolor=\darg{1 0 0},bgcolor=\darg{0 1 0},}%
\begin{dCmd*}{\aebdimen+2\fboxsep+2\fboxrule}
\pushButton[\ui{%
    bordercolor={1 0 0},bgcolor={0 1 0},
    textcolor={1 0 0},align={right},
    uptxt={Push Me},
    js={app.alert("AcroTeX rocks!")}
}]{pb1}{}{11bp}
\end{dCmd*}
\egroup\newtopic You can develop your own set of appearances and use the \texttt{presets} key to conveniently set these.
For example,
\begin{Verbatim}[xleftmargin=\amtIndent]
\def\myFavFive{%
    bordercolor={1 0 0},bgcolor={0 1 0},
    textcolor={1 0 0},align={right},
    uptxt={Push Me}
}
\end{Verbatim}
Later, a push button can use this preset, like so,
\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\ui{presets=\myFavFive,
    js={app.alert("AcroTeX rocks!")}}]{pb1}{}{11bp}
\end{Verbatim}
\newtopic which produces \pushButton[\ui{presets=\myFavFive, js={app.alert("AcroTeX rocks!")}}]{pb1}{}{11bp}\,
\footnote{The reader is reminded once again that the author has no understanding of colors.}

\newtopic You can mix your \cs{myFavFive} with different key-value pairs, such as a JavaScript action.

\handpoint In each of the subsequent subsections, the \pkg{eforms} key to its user-friendly counterpart is
displayed in the margin. Some of the user-friendly are a combination of
\pkg{eforms} KVs and are not represented in the margin in this case.

\subsection{The Appearance Tab}

We present these key-value pairs to model the user-interface of \app{Acrobat}.


\settowidth{\aebdimen}{\ttfamily border=visible|invisible}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
border=visible|invisible
\end{dCmd}
\CmdDescription Used with link annotations and determines whether the border
surrounding the bounding box of the link is visible. In the case of a link,
this is the Link Type: \textsf{Visible Rectangle} or \textsf{Invisible
Rectangle}. If you set border equal to \texttt{invisible}, that will set
border line width to zero \verb!\W{0}!. For forms, this key has no
counterpart in the user interface.

If this key is not specified, the \textsf{eforms}
follows the rule: If \texttt{colorlinks} option of  \textsf{hyperref} is used, the border is invisible;
otherwise, it is visible (and the default \texttt{linewidth} is 1). Use the border key to override
this behavior.

\settowidth{\aebdimen}{\ttfamily linewidth=thin|medium|thick}%
\def\1{\llap{\Cs{W}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1linewidth=thin|medium|thick
\end{dCmd}
\CmdDescription The \texttt{linewidth} of the border around a link
or a form. The user interface choices are \texttt{thin},
\texttt{medium}, and \texttt{thick}. This key-value is ignored if the
document author has set the border to \texttt{invisible}.

\settowidth{\aebdimen}{\ttfamily highlight=none|invert|outline|inset|push}%
\def\1{\llap{\Cs{H}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1highlight=none|invert|outline|inset|push
\end{dCmd}
\CmdDescription The highlight type for links and forms, choices are
\texttt{none}, \texttt{invert}, \texttt{outline}, \texttt{inset} and
\texttt{push}. The term \texttt{inset} is used with links, and
\texttt{push} is used with forms. They each have the same key value pair.

\settowidth{\aebdimen}{\ttfamily bordercolor=\anglemeta{num}\hardspace\anglemeta{num}\hardspace\anglemeta{num}}%
\def\1{\llap{\smash{\parbox[c]{\marginparwidth}{\raggedright\shortstack[l]{\Cs{BC}\,(forms) or\\\Cs{Color}\,(links)}}}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1bordercolor=!anglemeta(num)!hardspace!anglemeta(num)!hardspace!anglemeta(num)
\end{dCmd}
\CmdDescription The color of the border, when visible, in RGB color space.
For example, \texttt{bordercolor=1 0 0}, is the color red.

\settowidth{\aebdimen}{\ttfamily linestyle=solid|dashed|underlined|beveled|inset}%
\def\1{\llap{\Cs{S}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1linestyle=solid|dashed|underlined|beveled|inset
\end{dCmd}
\CmdDescription  The line style of the border, possible values are \texttt{solid},\texttt{dashed},
\texttt{underlined}, \texttt{beveled},and \texttt{inset}. Links do not support
the \texttt{beveled} option.

\settowidth{\aebdimen}{\ttfamily dasharray=\anglemeta{num}[\hardspace\anglemeta{num}]}%
\def\1{\llap{\Cs{D}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1dasharray=!anglemeta(num)[!hardspace!anglemeta(num)]
\end{dCmd}
\CmdDescription When a line style of \texttt{dashed} is chosen, you can specify a dash array.
The default is 3.0, which means a repeating pattern of 3 points of line, followed by 3 points of space.
A value of \texttt{dasharray=3~2} means three points of line, followed
by two points of space. When this key is used without a value, the value is 3.0.
When the \texttt{dashed} key is not present, 3.0 is used.

linktxtcolor

\settowidth{\aebdimen}{\ttfamily linktxtcolor=\anglemeta{named\_color}}%
\def\1{\llap{\Cs{linktxtcolor}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1linktxtcolor=!anglemeta(named_color)
\end{dCmd}
\CmdDescription Set the color of the link text. Ignored if the
\texttt{colorlinks} option of hyperref has not been taken.  The
value of \texttt{linktxtcolor} is a named color. For example,
\texttt{linktxtcolor=red}. The default is \verb|\@linkcolor| from hyperref.
This default can be changed by redefining \cs{@linkcolor}, or
redefining \cs{defaultlinkcolor}. If \verb!linktxtcolor={}! (an
empty argument), or simply \texttt{linktxtcolor}, no color is
applied to the text, the color of the text will be whatever the current color is.

\settowidth{\aebdimen}{\ttfamily annotflags=hidden|print|-print|noview|lock}%
\def\1{\llap{\Cs{F}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1annotflags=hidden|print|-print|noview|lock
\end{dCmd}

\CmdDescription This is a bit field, possible values are \texttt{hidden}, \texttt{print},
\texttt{-print}, \texttt{noview}, and \texttt{lock}. \textit{Multiple values can
be specified}. The values are ``or-ed'' together. Most all forms are printable
by default. If you don't want a form field to print specify \texttt{-print}.
For example, \verb|annotflags={-print,lock}| makes the field not printable and is
locked, so the field cannot be moved through the UI.


\settowidth{\aebdimen}{\ttfamily fieldflags=readonly|required|noexport|multiline|password|}%
\def\1{\llap{\Cs{Ff}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1fieldflags=readonly|required|noexport|multiline|password|
     notoggleoff|radio|pushbutton|combo|edit|
     sort|fileselect|multiselect|nospellcheck|
     noscrolling|comb|radiosinunison|commitonchange|
     richtext
\end{dCmd}
\CmdDescription There are a large number of field flags (\texttt{Ff}) that set a
number of properties of a field. This is a multiple-selection key as well. The
values are ``or-ed'' together.

Normally, a document author would not specify \texttt{radio},
\texttt{pushbutton} or \texttt{combo}. These properties are used by
\textsf{eforms} to construct a radio button field, a push button and a combo
box. The others can be used as appropriate.

\settowidth{\aebdimen}{\ttfamily maxlength=\anglemeta{num}}%
\def\1{\llap{\Cs{MaxLen}\hspace{\marginparsep}}}%%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1maxlength=!anglemeta(num)

\CmdDescription Use \texttt{maxlength} to limit the number of characters input into a text field.
Example: \texttt{maxlength=12}. When the \texttt{fieldflags} is set to \texttt{comb}, the value
of \texttt{maxlength} determines the number of combs in the field.

\end{dCmd}
\CmdDescription Enter a text value to appear as a tool tip. A tool
tip is text that appears in a frame when the user hovers the mouse
over the field. The link annotation does not have a tool tip
feature. Enclose in parentheses if the text string contains a comma;
for example, \verb|tooltip={Hi, press me and see what happens!}|.
The \texttt{tooltip} key obeys the \texttt{unicode} option. If the
unicode option of hyperref is in effect, then setting
\begin{Verbatim}[xleftmargin=\amtIndent]
tooltip = {J\"{u}rgen, press me and see what happens!}
\end{Verbatim}
\noindent yields a tool tip of ``J\"{u}rgen, press me and see what happens!''

\end{dCmd}
\CmdDescription Set default value of a field (text, list, combobox)
using the \texttt{default} key. The default value is the value used
for the field when the field is reset. Example:
\texttt{default=Name}.

The \texttt{value} key is used to set the current value of a
field (text, list, combobox). Example: \texttt{value=AcroTeX}. % unicode

These two keys obey the \texttt{unicode} option.
If the unicode option of hyperref is in effect, then setting
\verb|value = \texteuro\ 1 000 000| sets the (initial) value of this field to
``\char1 \ 1 000 000''.

!3rollovertxt=!anglemeta(string)
\end{dCmd}
\CmdDescription The normal (mouse up), mouse down and rollover text
for a button field. All three of these keys obey the \texttt{unicode} option.
If the \opt{unicode} option of \pkg{hyperref} is in effect, then setting
\verb!uptxt = J\"{u}rgen! yields a normal caption of ``J\"{u}rgen'' on the button.

\subsection{The Action Tab}

There are several common actions that are supported through the user-friendly interface, these
are \texttt{goto} actions, and JavaScript actions.


\settowidth{\aebdimen}{\ttfamily goto=\darg{\meta{KV-pairs}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
goto={!meta(KV-pairs)}
\end{dCmd}
\CmdDescription This key incorporates jumps to pages and destinations within the current PDF file,
and to pages and destinations to another PDF file. these are
\KVP There are a number of key-value pairs that are recognized,
\texttt{file}, \texttt{targetdest}, \texttt{labeldest}, \texttt{page},
\texttt{view}, and \texttt{open}. A brief description of each follows.
\begin{enumerate}
  \item \texttt{file}: Specify a relative path to the PDF file. This will work on the Web if
        the position is the same relative to the calling file. If the \texttt{file} key is not present,
        the jump is to a page or destination in the current file.
  \item \texttt{url}: This key is used to create a weblink, similar to what \cs{href} does.
        The value of this key is a url (\texttt{http}, \texttt{https}, \texttt{mailto}, etc.).
        If the \texttt{url} key is present, only the \texttt{openparams} key is recognized.
  \item \texttt{openparams}: Open parameters that should be included with the URL, as passed by
        the \texttt{url} key. These parameters are key value pairs \texttt{key=value} and are separated
        by an ampersand (\texttt{\&}).
        See \emph{\href{http://www.adobe.com/devnet/acrobat/?view=documentation}{Parameters for Opening PDF Files}} for more information, examples are found below.
  \item \texttt{targetdest}: Jump to a target, perhaps created by \verb|\hypertarget|. For example,
        if we say \verb|\hypertarget{acrotex}{Welcome!}|, we jump to the
        \texttt{acrotex} named destination by specifying \texttt{targetdest=acrotex}.
  \item \texttt{labeldest}: Same as \texttt{targetdest}, but we jump to a destination specified by
        a latex label. For example, if we type \verb|\section{AcroTeX}\label{acrotex}|,
        we can jump to this section by specifying \texttt{labeldest=acrotex}.

  \item \texttt{page}: The page number to which the \texttt{goto}
      action is to jump. If we set \texttt{page=1}, we will jump to the
      first page of the document.

  \item \texttt{view}: The view can be set when the \texttt{page} key is used.
    Possible values are \texttt{fitpage}, \texttt{actualsize},
    \texttt{fitwidth}, \texttt{fitvisible}, and \texttt{inheritzoom}.
    These terms correspond to \app{Acrobat}'s UI. When jumping to a
    destination, the view is set by the destination code.

  \item \texttt{open}: This key is used when you specify the \texttt{file} key. The
    \texttt{open} key determines if a new window is opened or not when the PDF viewer
    jumps to the file. Possible values are \texttt{userpref} (use user preferences),
    \texttt{new} (open new window), \texttt{existing} (use the existing window).

\end{enumerate}

\Example The following are examples of the \texttt{goto} key.
\begin{itemize}
    \item \setLink[\ui{goto={file=aeb_man.pdf,page=8,view=fitwidth}}]{AeB Manual}
\begin{Verbatim}[xleftmargin=\amtIndent]
\setLink[\ui{goto={file=aeb_man.pdf,page=8,%
    view=fitwidth}}]{AeB Manual}
\end{Verbatim}
This link should work on your local hard drive and it should work on
the web, from within a web browser, assuming \texttt{aeb\_man.pdf} is
in the same folder as \texttt{eformman.pdf}.

\item \setLink[\ui{goto={url=http://www.math.uakron.edu/~dpstory/acrotex/aeb_man.pdf,
    openparams={page=8&search=AcroTeX web exerquiz}}}]{AeB Manual on Web}
\begin{Verbatim}[xleftmargin=\amtIndent]
\setLink[\ui{%
    goto={url=http://www.math.uakron.edu/~dpstory/%
        acrotex/aeb_man.pdf,%
    openparams={page=8&search=AcroTeX web exerquiz}}}
        ]{AeB Manual on Web}
\end{Verbatim}
Here, we open the AeB Manual that is on the web, go to page 8, and search for the words
\texttt{AcroTeX}, \texttt{web}, and \texttt{exerquiz}.  Notice that we don't have to
do anything special with the tilde (\texttt{\string~}) or the sharp (\texttt{\#}), both of
these are handled by the \textsf{eforms} package.
\end{itemize}


\settowidth{\aebdimen}{\ttfamily js=\darg{\anglemeta{script}}}%
\def\1{\llap{\ttfamily\Cs{A}\darg{\Cs{JS}\darg{\anglemeta{script}}}\hspace{\marginparsep}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}

\CmdDescription A general purpose key to execute JavaScript actions on a mouse up trigger.
The argument is a JavaScript text string, for example,
\begin{Verbatim}[xleftmargin=\amtIndent]
js={app.alert("Hello World!")}
\end{Verbatim}
The value of \texttt{js} may be a macro containing JavaScript, which would include
a macro created by the \texttt{defineJS} environment of \textsf{insdljs}.

% Next up are additional actions, and there are a lot of them. All these
% take JavaScript code as their values.
\settowidth{\aebdimen}{\ttfamily pageinvisible=\darg{\anglemeta{script}}}

pageopen={!anglemeta(script)}
pageclose={!anglemeta(script)}
pagevisible={!anglemeta(script)}
pageinvisible={!anglemeta(script)}
\end{dCmd}
\CmdDescription These are all additional actions (\texttt{AA}) of a form field, which take as their values
JavaScript code (\anglemeta{script}).
 \begin{itemize}
   \item \texttt{mouseup}: Executes its code with a mouse up event. If there is a JavaScript
         action defined by the \texttt{js} key (or the \verb|\A| key), the \texttt{js} (\verb|\A|) action is executed.
   \item \texttt{mousedown}: Executes its when the mouse is hovering over the field and the user clicks
         on the mouse.
   \item \texttt{onenter}: Executes its code when the user moves the mouse into the form field (the bounding rectangle).
   \item \texttt{onexit}: Executes its code when the user moves the mouse out of the form field (the bounding rectangle).
   \item \texttt{onfocus}: Executes its code when the user brings the field into focus.
   \item \texttt{onblur}: Executes its code when the user brings the field loses focus (the user tabs away from
         the field, or click outside the field).
   \item \texttt{format}: JavaScript to format the text that appears to
           the user in a text field or editable combo box.
   \item \texttt{keystroke}: JavaScript to process each keystroke in a text field or editable combo box.
   \item \texttt{validate}: JavaScript to validate the committed data input into a text field or editable combo box.
   \item \texttt{calculate}: JavaScript to make calculations based on the values of other fields.
   \item \texttt{pageopen}: JavaScript that executes when the page containing the field is opened.
   \item \texttt{pageclose}: JavaScript that executes when the page containing the field is closed.
   \item \texttt{pagevisible}: JavaScript that executes when the page containing the field first becomes visible to the user.
   \item \texttt{pageinvisible}: JavaScript that executes when the page containing the field is no longer visible to the user.
 \end{itemize}

 \subsection{The Signed Tab}

 A signature field has a Signed tab. On that tab is an option to mark a set of fields
 as readonly (locked). The locked key controls that option.

\settowidth{\aebdimen}{\ttfamily lock=\darg{\anglemeta{PDF KV-pairs}}}
\def\1{\llap{\Cs{Lock}\hspace{\marginparsep}}}%Lock
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
!1lock={!anglemeta(PDF KV-pairs)}
\end{dCmd}

\CmdDescription The \texttt{lock} key is used with signature fields, currently, there is
 no nice user interface to this key. Typical entries are
\begin{Verbatim}[xleftmargin=\amtIndent]
lock={/Action/All}         % lock all fields in the doc
lock={/Action/Include      % lock all fields listed in Fields
    /Fields [(field1)(field2)...]}
lock={/Action/Exclude      % lock all fields not listed in Fields
    /Fields [(field1)(field2)...]}
\end{Verbatim}

\newtopic Another option that is included in the Signed tab is titled ``This script executes
when field is signed.''

This is an option that, through the user interface, is mutually exclusive from
locking fields. This option is implemented through the format event;
thus, to populate this option with JavaScript use the \texttt{format} key. For example,
\begin{Verbatim}[xleftmargin=\amtIndent]
format={app.alert("Thank you for signing this field.");}
\end{Verbatim}

\part{Setting the Tab Order}

The \hypertarget{\pkg{taborder}}{taborderPkg} package is an internal AeB package that is called by
both the \textsf{eforms} and the \texttt{annot\_pro packages}. The
\texttt{taborder} package sets the tab order for form fields and link
annotations (when the link is created by the command \cs{setLink}, defined
in the \textsf{eforms} package. The package works for all drivers when
setting tab order by column, row, or widget order. For setting tabbing
order by structure, only documents generated using the \textbf{pdfmark}
are supported; those using the \textsf{dvips} or \textsf{dvipsone} driver along with Adobe
Distiller.

\section{Setting the Tab Order}

The tabbing order of the fields is usually the order in which the fields were created. In rare cases, it may be desirable to set the order to one of the orders defined by the PDF Reference.
\settowidth{\aebdimen}{\ttfamily \string\setTabOrder\darg{c|C|r|R|s|S|w|W|a|A|unspecified}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\setTabOrder{c|C|r|R|s|S|w|W|a|A|unspecified}
\end{dCmd}

\CmdDescription Command Description: This command is page oriented, it sets to the tab order of fields on
the page the TEX compiler executes this command. The permissible values of the parameter are
described below, taken verbatim from the \emph{PDF Reference}, the cross-references that appear in the
descriptions are references to the \emph{PDF Reference} document.
\begin{itemize}
\item \texttt{c|C} (column order): ``Annotations are visited in columns running vertically up and down
the page. Columns are ordered by the Direction entry in the viewer preferences dictionary
(see Section 8.1, `Viewer Preferences'). The first annotation visited is the one at the top of
the first column. When the end of a column is encountered, the first annotation in the next
column is visited.''
\item  \texttt{r|R} (row order): ``Annotations are visited in rows running horizontally across the page.
The direction within a row is determined by the Direction entry in the viewer preferences
dictionary (see Section 8.1, `Viewer Preferences'). The first annotation visited is the first
annotation in the topmost row. When the end of a row is encountered, the first annotation
in the next row is visited.''
\item \texttt{s|S} (structure order): ``Annotations are visited in the order in which they appear in the
structure tree (see Section 10.6, ``Logical Structure''). The order for annotations that are not
included in the structure tree is application-dependent.''
\item \texttt{w|W} (version 9.0, widget order): ``Widget annotations are visited in the order in which they
appear in the page Annots array, followed by other annotation types in row order.''
\item \texttt{a|A} (version 9.0, annotations array order): ``All annotations are visited in the order in which
they appear in the page Annots array.'' (In version 9.0, this key is not implemented.)
\item \texttt{unspecified|empty} The tab order follows the order of the annotations as listed in the
Annots array. For LATEX, this is the order in which the annotations were created. You get
the same result if the argument is left empty \verb!\setTabOrder{}!, or if \cs{setTabOrder} is
not used at all. If an unrecognized argument is passed to \cs{setTabOrder}, \texttt{unspecified}
is used.
\end{itemize}
The behavior of tabbing has changed over the years; documentation of tabbing behavior is given
in the \emph{Adobe Supplement to the ISO 32000, BaseVersion 1.7, ExtensionLevel 3}.\footnote{\url{http://www.adobe.com/devnet/acrobat/pdfs/PDF3200_2008.pdf}} See the section
Errors and Implementation Notes. Annotations include things like form fields (widget annotations), links (link annotations) and
the various types of comment annotations. See section 8.4.5 of the PDF Reference.

The \cs{setTabOrder} command is available for users of pdftex and dvipdfm, as well as users of dvipsone and dvips (with distiller); for row, column, and widget (version 9 or later), the PDF viewer does all the work on tabbing, for tabbing using structure, one necessarily needs structure, otherwise, the tabbing follows row order. For users of Adobe Distiller, the \texttt{taborder} package provides two ways for defining the structure order; on any page in which structure order is used, use only one of the following commands:
\settowidth{\aebdimen}{\ttfamily\string\setTabOrderByNumber}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\setTabOrderByList
\setTabOrderByNumber
\end{dCmd}

\subsection{Using \texorpdfstring{\protect\cs{setTabOrderByList}}{\CMD{setTabOrderByList}}}

We illustrate with a simple example, followed by a verbatim listing of the code, and a discussion
afterward. We begin by placing two text fields in a row; normally,we would tab from the first one created
by the {\TeX} compiler to the next one created. We use structure to reverse the order of tabbing.

\setTabOrder{s}     % set tab order to structure
\setTabOrderByList  % the default initially

\textField[\V{text1}\objdef{otext1}]{text1}{1.25in}{11bp}\\[3bp]
\textField[\V{text2}\objdef{otext2}]{text2}{1.25in}{11bp}

\setStructTabOrder{% The list of the fields in the desired order
    {otext2}
    {otext1}
}
\newtopic The verbatim listing of the above form fields follows:
\begin{Verbatim}[xleftmargin=\amtIndent]
\setTabOrder{s}     % set tab order to structure
\setTabOrderByList  % the default initially

\textField[\V{text1}\objdef{otext1}]{text1}{1.25in}{11bp}\\[3bp]
\textField[\V{text2}\objdef{otext2}]{text2}{1.25in}{11bp}

\setStructTabOrder{% The list of the fields in the desired order
    {otext2}
    {otext1}
}
\end{Verbatim}
\newtopic We begin by specifying \verb!\setTabOrder{s}! structure tab order. In the optional argument of the two text fields, we specify an object name for each. These names must be unique throughout the whole document; they are used to reference the fields when setting up the tabbing order.

The \cs{setStructTabOrder} is used to set up the tabbing order, its arguments (enclosed in
braces) consists of a list of object names (which must exist on the current page). The order of
the object names is the order of visitation when you tab. PDF objects not referenced are visited
last after the structure tabbing is complete.

After all annotations have been created on a page, we use the \cs{setStructTabOrder} to
actually set the tab order; this is none by simply listing the object names, in the desired order, of
the annotations you want included in the tabbing order. These annotations can be fields, links,
and markup comments, like sticky notes.

The syntax for \cs{setStructTabOrder} is

\bgroup\obeyspaces%
\settowidth{\aebdimen}{\ttfamily    [type=\anglemeta{type},title=\anglemeta{title}]\darg{\anglemeta{oRef\_n}}}%
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\setStructTabOrder{%
    [type=!anglemeta(type),title=!anglemeta(title)]{!anglemeta(oRef_1)}
    [type=!anglemeta(type),title=!anglemeta(title)]{!anglemeta(oRef_1)}
    ...
    [type=!anglemeta(type),title=!anglemeta(title)]{!anglemeta(oRef_n)}
}
\end{dCmd}
\egroup\newtopic Each argument has an optional argument, the required argument (\anglemeta{<oRef\_i>}) is an object name
of a previously defined PDF object, such as a form field (widget), a link, or an annotation. The
optional argument takes two optional key-value pairs: (1) The type is a declaration of the type
the PDF object is, the default is \texttt{Form} (you can use \texttt{Link} if its a link, and \texttt{Annot} if its a comment);
(2) \texttt{title} is the title of the structure, the value of title appears in the Tags panel of the \app{Acrobat}
user interface. The default title is to have no title.

including tabbing using structure, has its source file attached to the PDF file.
The file is posted one the \href{\urlAcroTeXBlog}{AeB Blog}.

\subsection{Using \texorpdfstring{\protect\cs{setTabOrderByNumber}}{\CMD{setTabOrderByNumber}}}

An alternate method for setting tab order by structure is to directly enter the tab order into the
optional argument of the field, link, or comment annotation.

\setTabOrder{s} % set tab order to structure
\setTabOrderByNumber

\textField[\V{text3}\objdef{otext3}\taborder{1}]{text3}{1.25in}{11bp}\\[3bp]
\textField[\V{text3}\objdef{otext4}\taborder{0}]{text4}{1.25in}{11bp}

\newtopic The verbatim listing of the above form fields follows:
\begin{Verbatim}[xleftmargin=\amtIndent,]
\setTabOrder{s} % set tab order to structure
\setTabOrderByNumber

\textField[\V{text3}\objdef{otext3}\taborder{1}]
    {text3}{1.25in}{11bp}\\[3bp]
\textField[\V{text3}\objdef{otext4}\taborder{0}]
    {text4}{1.25in}{11bp}
\end{Verbatim}
\newtopic Note the user of the \cs{objdef} and \cs{taborder} keys. The latter is used to set the order of tabbing.

\newtopic\textcolor{red}{\textbf{Important:}} When setting tab order, there must be an object with \verb!\taborder{0}!; from what I've been able to observe, if no PDF object has tab order zero, the tabbing reverts to what is listed in the Annots array, which is the order the PDF objects were created. If you specify 0, 0, 1, 2, 3\dots, then the two PDF objects with tab order of 0 are visited in the order they were created. Similarly, for the other tab values. A tab order of 0, 2, 3, 4\dots seems to work as well. The object labeled 2 will be visited after the object labeled 0.

\part{Document and Page JavaScript}

%\section{Introduction}

The \hypertarget{\pkg{insdljs}}{insdljsPkg} package provides support to {\LaTeX} in four areas:
\begin{enumerate}
  \item for embedding document level JavaScript into the PDF file created
      from a {\LaTeX} source, the \texttt{insDLJS} environment.
  \item for creating open page actions that are executed when the document
      is first opened to the first page, the \cs{OpenAction} command.
  \item for writing JavaScript code in an environment that preserves the
      formatting of the code, this is the \texttt{defineJS} environment.
  \item for executing JavaScript code once to perform post-distillation
      tasks, this is the \texttt{execJS} environment. This environment
      works only for document authors that use \app{Acrobat}/\app{Acrobat}
      Distiller to create PDF files.
\end{enumerate}

\newtopic This package defines a new environment, \texttt{insDLJS}, used
for inserting \app{Acrobat} JavaScript into a PDF file created from a
\LaTeX{} source. This package works correctly for users of \textsf{pdftex}
(and \app{luatex}), \textsf{dvipdfm}, \textsf{dvipdfmx}, and \texttt{xetex}.
For\marginpar{\small\raggedleft\app{Acrobat} required for
\app{dvips}} those who use either \app{dvips} or
\app{dvipsone} to produce a postscript file, which is then distilled, you are
required to have \app{Acrobat}~5.0 (or later).

\section{Package Options}

The \textsf{insdljs} supports five common ``drivers'': \texttt{dvipsone},
\texttt{dvips}, \texttt{pdftex} (including the executable \textsf{lu(la)tex}), \texttt{dvipdfm},
\texttt{dvipdfmx}, \texttt{xetex}, and \texttt{tex\-tures}. When using
\texttt{dvipsone} or \texttt{dvips}, \app{Acrobat} Distiller and \app{Acrobat}
(version 5.0 or later) are required to embed the JavaScripts at the
document level. The other drivers have primitives that allow the embedding
of the JavaScripts.

\newtopic Other options are discussed in the following paragraphs.
\begin{description}\def\NH{\hspace{-\labelsep}}
\item\NH\texttt{nodljs} turns off the embedding of the document level
    JavaScript. This might be useful, for creating a paper document that is
    not interactive. For a non-interactive paper document, no JS is needed.

\item\NH\texttt{execJS} is a very useful option/feature if you know  how to use
    it.  Any JavaScript that is written in an \env{execJS} environment is
    executed once when the document is first opened in \app{Acrobat}, then
    discarded. AeB uses this for post-distillation document processing. The
    default is that the JavaScript in an \texttt{execJS} environment is not
    executed; using this option turns on this feature.
\end{description}

\section{The \texttt{insDLJS} and \texttt{insDLJS*} Environments}

These are the main environments defined by this package. There are
two forms of the document level environment, the \texttt{insDLJS} and the
\texttt{insDLJS*}.  First, we discuss what a document JavaScript is.

\subsection{What is Document Level JavaScript?}
The document level is a location in the PDF document where scripts can be stored.
When the PDF document is opened, the document level functions are scanned, and any
``exposed script'' is executed.

Normally, the type of scripts you would place at the document level are
general purpose JavaScript functions, functions that are called repeatedly
or large special purpose functions.  Functions at the document level are
known throughout the document, so they can be called by links, form
buttons, page open actions, etc.

Variables declared within a JavaScript function have local scope, they are
not known outside that function. However, if you can declare variables and
initialize them at the document level outside of a function, these
variables will have document wide scope. Throughout the document, the
values of these global variables are known. For example, suppose the
following code is at the document level:
\begin{Verbatim}[xleftmargin=\amtIndent]
var myVar = 17;       // defined outside a function, global scope
function HelloWorld()
{
    var x = 3;        // defined inside a function, local scope
    app.alert("AcroTeX, by Hech!", 3);
}
\end{Verbatim}
Both the function \texttt{HelloWorld()} and the variable \texttt{myVar}
are known throughout the document. The function \texttt{HelloWorld()} can
be called by a mouse up button action; some form field, executing some
JavaScript, may access the value of \texttt{myVar} and/or change its
value.  The variable \texttt{x} is not known outside of the
\texttt{HelloWorld()} function.

\subsection{The \texttt{insDLJS} Environment}

The \texttt{insDLJS} is the simplest of the two environments. Any material
within the environment, eventually ends up in the \textsf{DLJS} section of the
PDF document.

The environment takes the \meta{base\_name} and writes the
file \texttt{\anglemeta{base\_name}.djs}. This file contains a verbatim
listing of the JavaScript within the environment, plus some lines
that change catcodes. The file is then input into the document at
\cs{AtBeginDocument}.

The case of \textsf{dvipsone} and \textsf{dvips} is a little different. A
\texttt{\anglemeta{base\_name}.djs} is written and input back, and a second file
\texttt{\anglemeta{base\_name}.fdf} is written. The second file is later input
into the PDF document after distillation.

The syntax of usage for this environment, which takes three
arguments, is given next.
\settowidth{\aebdimen}{\cs{begin\darg{insDLJS}[\meta{js\_var}]\darg{\meta{base\_name}}\darg{\meta{script\_name}}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\begin{insDLJS}[!meta(js_var)]{!meta(base_name)}{!meta(script_name)}
...
    !anglemeta(JavaScript functions or exposed code)
...
\end{insDLJS}
\end{dCmd}
\EnvDescription JavaScript code is written within the \texttt{insDLJS} environment.
The code is stored as document-level JavaScript, and is global to the document. Functions
and variables defined at the top-most level are known to other form elements in the document.

The \texttt{insDLJS} is a verbatim environment, with backslash (\verb!\!)
and percentage (\texttt{\%}) maintaining their usual {\LaTeX} meaning.
Commands defined in the {\LaTeX} source file, therefore, are expanded
before the JavaScript is embedded in the PDF file. The left and right
braces are set to normal characters, so the commands can't have any
argument, they should be just text macros.

\PD The environment takes three parameters, the first is optional, but required
when  using the \app{Acrobat} Distiller.
\begin{description}\def\NH{\hspace{-\labelsep}}%
\item\NH\texttt{[\meta{js\_var}]} is an
    optional parameter \emph{was required} for the \texttt{dvipsone}
    and \texttt{dvips} options; otherwise it is ignored. Its value
    must be the name of one of the functions or JavaScript variables
    defined in the environment. This is used to detect whether the
    \textsf{DLJS} has already been loaded by \app{Acrobat}.

\handpoint The \texttt{[\meta{js\_var}]} is now optional even for
    users of \textsf{dvipsone} and \textsf{dvips}. If one is not
    provided, then appropriate code is automatically generated.

\item\NH \meta{base\_name} is an alphabetic word with no spaces and limited
    to eight characters.\footnote{There is actually no limitation on the
    number of characters in the name, this is a legacy statement from the
    days of DOS, you remember DOS, don't you?}  It is used to build the
    names of auxiliary files and to build the names of macros used by the
    environment.

\item\NH\meta{script\_name} is the name of the JavaScript that you are
    embedding in the document. This title will appear in the document
    JavaScript dialog in \app{Acrobat}; unless you use \app{Acrobat}, you can't
    see this name in the user interface anyway. The
    \meta{script\_name} should be a string that is descriptive of
    the functionality of the code.
\end{description}

\paragraph*{Commenting.} Within the \texttt{insDLJS} environment, there
are two types of comment characters: (1) a \TeX{} comment (\verb|%|) and
(2) a JavaScript comment.   The JavaScript comments are `\texttt{//}', a
line comment, and `\texttt{/*...*/}' for more extensive commenting. These
comments will survive and be placed into the PDF file. In JavaScript the
`\verb|%|' is used as well, use \verb|\%| when you want to use the percent
character in a JavaScript statement, for example \verb|app.alert("\%.2f", 3.14159);|,
this statement will appear within your JavaScript code as \verb|app.alert("%.2f", 3.14159);|.


\Example The following is a minimal illustration of the use of the
new environment. Here we assume the document author is using pdftex,
and is not using the wonderful packages of \textsf{web},
\textsf{exerquiz} or \textsf{eforms}. In this case, the hyperref
package with driver in the option must be introduced first, followed
by \textsf{insdljs} with the same driver, of course. The optional argument
of the \texttt{insDLJS} environment is not used in this example.
\begin{Verbatim}[xleftmargin=\amtIndent]
\documentclass{article}
\usepackage[pdftex]{hyperref}
\usepackage[pdftex]{insdljs}

\newcommand\tugHello{Welcome to TUG 2001!}
\begin{insDLJS}{mydljs}{My Private DLJS}
function HelloWorld() { app.alert("\tugHello", 3); }
\end{insDLJS}
\begin{document}
\begin{Form}     % a hyperref environment, needed for \PushButton
% use built in form button of hyperref
Push \PushButton[name=myButton,onclick={HelloWorld();}]{Button}
\end{Form}
\end{document}
\end{Verbatim}
\noindent The Form environment and the \cs{PushButton} command are defined
in the hyperref package. The \textsf{insDLJS} uses the Form environment,
the \textsf{eforms} package defines its own \cs{pushButton} command.

\Example Here is the same example as above, but with \textsf{dvips} as the
driver and using the \textsf{eforms} package, which calls
\textsf{insdljs}. Note the  use of the optional argument in the
\texttt{insDLJS} environment, and the missing \textsf{hyperref} package
statement and \texttt{Form} environment, the \textsf{eforms} package
automatically inserts this code.
\begin{Verbatim}[xleftmargin=\amtIndent]
\documentclass{article}
\usepackage[dvips]{eforms}

\newcommand\tugHello{Welcome to TUG 2001!}
\begin{insDLJS}[HelloWorld]{mydljs}{My Private DLJS}
function HelloWorld() { app.alert("\tugHello", 3); }
\end{insDLJS}
\begin{document}
\pushButton[\CA{Push}\A{\JS{HelloWorld();}}]{Button}{}{11bp}
\end{document}
\end{Verbatim}

\subsection{The \texttt{insDLJS*} Environment}

The \texttt{insDLJS*} environment can be used to better organize,
edit and debug your JavaScript. It is suitable for package
developers who write a large amount of code package application.

If you have the full \app{Acrobat} product, you can open the DLJS edit
dialog. There you will see a listing of all DLJS contained in the
document. When you double click on one of the \textit{script names},
you enter the edit window, where you can edit all JavaScript
contained under that name.

\bgroup\obeyspaces%
\settowidth{\aebdimen}{\ttfamily    \anglemeta{JavaScript functions or exposed code}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\begin{insDLJS*}[!meta(js_var)]{!meta(base_name)}
\begin{newsegment}{!meta(script_name_1)}
    !anglemeta(JavaScript functions or exposed code)
\end{newsegment}
\begin{newsegment}{!meta(script_name_2)}
    !anglemeta(JavaScript functions or exposed code)
\end{newsegment}
...
...
\begin{newsegment}{!meta(script_name_n)}
    !anglemeta(JavaScript functions or exposed code)
\end{newsegment}
\end{insDLJS*}
\end{dCmd}
\egroup
\PD The environment takes two parameters, the first is optional, but required
when  using the \app{Acrobat} Distiller. The nested environment \texttt{newsegment} takes
one required parameter.
\begin{description}\def\NH{\hspace{-\labelsep}}
\item\NH\texttt{[\meta{js\_var}]} is an optional parameter, its use is discouraged.

\item\NH\meta{base\_name} is an alphabetic word with no spaces and
    limited to eight characters. It is used to build the names of auxiliary
    files and to build the names of macros used by the environment.
\item\NH\meta{script\_name\_i} is the script name (title) that appears in
    the Document level JavaScript dialog of \app{Acrobat}.
\end{description}

\subsection{Escaping}

JavaScript uses the backslash as an escape character, just as does \TeX. The insdljs pacakge
tries to make the transition from {\TeX} to JavaScript as easy as possible. In the table below,
is a listing of the more useful characters represented by a backslash.

\begin{tabular}{ll}
Sequence & Character represented \\
\cs{t}   & horizontal tab (\cs{u0009}) \\
\cs{n}   & newline (\cs{u000A}) \\
\cs{r}   & carriage return (\cs{u000D}) \\
\cs{"}   & double quote (\cs{u0022}) \\
\cs{'}   & apostrophe or single quote (\cs{u0027}) \\
\verb|\\|     & backslash (\cs{u005C})\\
\cs{xXX} & the Latin-1 character specified by the two hexadecimal digits \texttt{XX} \\
\cs{uXXXX}& the unicode character specified by the four hexadecimal digits \texttt{XXXX} \\
\cs{XXX} & the Latin-1 character specified by the octal digits \texttt{XXX}, between \\
      & 1 and 377. \\
\end{tabular}

\newtopic Within a JavaScript string, these special characters should be double escaped, \verb|\\|, like so:

\newtopic \pushButton[\textFont{Arial}\CA{Push Me}\A{\JS{%
    app.alert("The \\"cost\\" of this package is \\u20AC 0.\\rThis, \\"\\\\\\" is a backslash");
}}]{demoEsc}{}{11bp}

\begin{Verbatim}[xleftmargin=\amtIndent]
\pushButton[\textFont{Arial}\CA{Push Me}\A{\JS{%
    app.alert("The \\"cost\\" of this package is \\u20AC 0.\\rThis,
    \\"\\\\\\" is a backslash");
}}]{demoEsc}{}{11bp}
\end{Verbatim}
\newtopic Note the double backslash of backslash, which comes out to four, count them four backslashes,
`'\verb|\\\\|''.

Again, both JavaScript and \TeX, certain punctuation marks have special meaning; in the case of
JavaScript, punctuation has a special meaning within regular expressions:
\begin{flushleft}
\textbf{Special Punctuation in Regular Expressions}
\begin{Verbatim}[xleftmargin=\amtIndent]
     ^ $ . * + ? = ! : | \ / ( ) [ ] { }
\end{Verbatim}
\end{flushleft}
\noindent When these occur in a regular expression, within a string, they need to be double escaped, \verb|\\|.
Outside of a sting, they need only be escaped.

\Example The following code searches through the string \texttt{str} and
replaces every occurrence of the period character with ``\verb|\.|''.
\begin{Verbatim}[xleftmargin=\amtIndent]
str = "AcroTeX rocks. AcroTeX rolls."
str = str.replace(/\./g, "\\.");
\end{Verbatim}
\noindent When this code is executed, the result is
``AcroTeX rocks\verb|\.| AcroTeX rolls\verb|\.|''.

\Example If one of these special characters appears outside a
JavaScript string, within a regular expression pattern, for example,
they need only be escaped. The code \verb|(/\)\^\(/.test(str))|
searches the string \texttt{str} for any occurrence of ``\verb!)^(!''
and returns \texttt{true} if such a pattern is found, \texttt{false}
otherwise. If \verb!str="(x+1)^(3)"!, the search returns \texttt{true}.

\subsection{Access and Debugging}
For those who do not have \textsf{\app{Acrobat}}, the application,
unless you are writing very simple code, writing and debugging
JavaScript will be very difficult.  From the \app{Acrobat} Reader,
there is no access to the document JavaScript. You will be
pretty much writing blind.

Normally, I develop the JavaScript from within \app{Acrobat}. The GUI editor
does check for syntax errors, giving you a chance to correct some simple
errors as you go. After I am satisfied with my code, I copy it from the
editor and paste it into a \texttt{insDLJS} environment. This is how the
JavaScript code of \textsf{exerquiz} was developed.

In my opinion, if you want to develop rather complicated code, having the
full \app{Acrobat} product is a must. (This implies that the Windows or Mac
platform is needed!)

\subsection{JavaScript References}

The JavaScript used by \app{Acrobat} consists of the core JavaScript plus \app{Acrobat}'s JavaScript extensions.
The \textit{Core JavaScript Reference}~\cite{tech:NetscapeJSReference} may be found at
\mlhref{http://developer.mozilla.org/en/docs/JavaScript}{Mozilla Developer Center}.
The documentation for the \app{Acrobat} extensions may be found in the guides
\textit{JavaScript for \app{Acrobat} API Reference}~\cite{tech:AcroJSRef}
and \textit{Developing \app{Acrobat} Applications using JavaScript}~\cite{tech:AcroJSGuide}, both of which I've had a hand in writing. These
are found at \href{http://www.adobe.com/devnet/acrobat/}{\app{Acrobat} Developer Center}. (Click on \textbf{JavaScript for \app{Acrobat}} in the right-hand navigation panel.)

\section{Open Action}

This package also defines an \cs{OpenAction} command to introduce actions that are
executed when the PDF document is  opened on page~1. The open action command only
applies to page~1.
\settowidth{\aebdimen}{\ttfamily\string\OpenAction\darg{\meta{action\_code}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\OpenAction{!meta(action_code)}
\end{dCmd}
\CmdLoc This command must appear in the preamble of the document.

\CmdDescription Executes the action(s) each time page~1 is
opened. The argument \texttt{<action\_code>} is any action subtype, as listed
in Section 8.5.3 of the \emph{PDF Reference, sixth edition, PDF
1.7}. Two common types are JavaScript and Named actions. The \cs{OpenAction}
command may be repeated, which will add to the list of open actions
to be executed at the opening of page~1.

Special commands are defined in \textsf{insdljs}, \cs{JS} and \cs{Named}, that
make it easy to specify these types of actions.

\Example \verb|\OpenAction{\JS{app.alert("Hello World!");}}|

\Example You can use \cs{r} and \cs{t}---carriage return and tab,
respectively---to format multiple lines of JavaScript:
\begin{Verbatim}[xleftmargin=\amtIndent]
\OpenAction{\JS{%
    app.alert("Hello World!");\r
    app.alert("Good Day to You!");
}}
\end{Verbatim}

\Example Multiple \cs{OpenAction} can be entered. Code is executed in the same order.
Here, we show an alert box with a message, then jump to the last page.
\begin{Verbatim}[xleftmargin=\amtIndent]
\OpenAction{\JS{app.alert("AcroTeX rocks the world!");}}
\OpenAction{\Named{LastPage}}
\end{Verbatim}

\newtopic For the other pages, beyond page~1, \cs{thisPageAction} can be used;
the command can also be used for page~1 as well (it must go in the
preamble).

\settowidth{\aebdimen}{\ttfamily\string\thisPageAction\darg{\meta{open\_script}}\darg{\meta{close\_script}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\thisPageAction{!meta(open_script)}{!meta(close_script)}
\end{dCmd}
\CmdLoc For page~1, this command must go in the preamble, otherwise, it
goes on the page for which it is intended.

\CmdDescription \meta{open\_script} is an action that is to be
executed when the current page is opened; \meta{close\_script} is an
action to be executed when the current page is closed.

\Example Below is a simple example of how to use \cs{thisPageAction}.
\begin{Verbatim}[xleftmargin=\amtIndent]
...
\thisPageAction{\JS{console.println("Open: page 1");}}
    {\JS{console.println("Close: page 1");}}
\begin{document}
page 1
\newpage
page 2
\thisPageAction{\JS{console.println("Open: page 2");}}
    {\JS{console.println("Close: page 2");}}
...
\end{document}
\end{Verbatim}
When \cs{thisPageAction} is executed in the preamble,
the \texttt{<open\_action>} argument gets passed to
the \cs{OpenAction} command.

\section{The \textsf{execJS} Environment}

This is an environment useful to PDF developers who want to tap into
the power of JavaScript. To use this environment, the developer
needs \app{Acrobat}~5.0 or higher. \textsf{pdftex} or \textsf{dvipdfm} can
be used to produce the PDF document, but the developer needs
the \app{Acrobat} product for this environment to do anything.

The \texttt{execJS} is used primarily for post-distillation
processing (post-creation processing, in the case of \textsf{pdftex}
and \textsf{dvipdfm}). The \texttt{execJS} environment can be used,
for example, to automatically import named icons into the document,
which can, in turn, be used for an animation.

The \textsf{execJS} is an environment in which you can write
verbatim JavaScript code. This environment is a variation on
\textsf{insdljs}, it writes a couple of auxiliary files to disk; in
particular, the environment creates an \texttt{.fdf} file. When the
newly produced PDF is loaded for the first time into the viewer
(\app{Acrobat}, not Reader), the \texttt{.fdf} file generated
by the \textsf{execJS} environment is imported, and the JavaScript
executed. This JavaScript is \emph{not} saved with the document.
The syntax of this environment is\dots

\settowidth{\aebdimen}{\ttfamily\string\begin\darg{execJS}\darg{\meta{name}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\begin{execJS}{!meta(name)}
....
!anglemeta(JavaScript code)
....
\end{execJS}
\end{dCmd}

\PD The environment takes one required argument, the base name of the
auxiliary files to be generated.

Many of the more useful JavaScript methods have security restrictions,
the developer must create folder JavaScript that can be used to \emph{raise
the privilege} of the methods.

\Example Here is an extensive example taken from the AeB Pro distribution.
The following code is user folder JavaScript code, see the AeB Pro documentation
on how to locate the user JavaScript folder. We define a function \texttt{aebTrustedFunctions}
that is the interface to accessing the restricted methods.
\begin{Verbatim}[xleftmargin=\amtIndent]
/*
    AEB Pro Document Assembly Methods
    Copyright (C) 2006 AcroTeX.Net
    D. P. Story
    http://www.acrotex.net
    Version 1.0
*/
if ( typeof aebTrustedFunctions == "undefined") {
    aebTrustedFunctions = app.trustedFunction(
        function ( doc, oFunction, oArgs ) {
        app.beginPriv();
            var retn = oFunction( oArgs, doc )
        app.endPriv();
        return retn;
    });
}
// Add a watermark background to a document
aebAddWatermarkFromFile = app.trustPropagatorFunction (
    function ( oArgs, doc ) {
    app.beginPriv();
        return retn = doc.addWatermarkFromFile(oArgs);
    app.endPriv();
});
\end{Verbatim}

Once this code is installed in the user JavaScript folder, and \app{Acrobat} is re-started, the code
is ready to be used. The way the code is used is with the \texttt{execJS} environment.

\begin{Verbatim}[xleftmargin=\amtIndent]
\def\bgPath{"/C/acrotex/ManualBGs/Manual_AeB.pdf"}
\begin{execJS}{execjs}
    aebTrustedFunctions( this, aebAddWatermarkFromFile,
        {bOnTop: false, cDIPath: \bgPath} )
\end{execJS}
\end{Verbatim}

\newtopic This is the code used to prepare this manual. It places a
background graphic on each page of the document.  When the newly
distilled document is first opened in \app{Acrobat}, (version 7.0 or
higher, is when the privilege bit started to appear), the trusted
function \texttt{aebTrustedFunctions} is executed with its
arguments. Looking at the definition of
\texttt{aebTrustedFunctions}, what is executed is
\begin{Verbatim}[xleftmargin=\amtIndent]
app.beginPriv();
    return retn = this.addWatermarkFromFile({bOnTop: false,
        cDIPath: "/C/acrotex/ManualBGs/Manual_AeB.pdf"});
app.endPriv();
\end{Verbatim}
\newtopic AeB Pro, the {Acro\!\TeX} Presentation Bundle and @EASE use these execJS techniques.

\section{The \textsf{defineJS} Environment}\label{defineJS}

When you create a form element (button, text field, etc.), you
sometimes want to attach JavaScript.  The \texttt{defineJS}
environment aids you in writing your field level JavaScript. It too
is a verbatim environment, however, this environment does not write to an auxiliary
file, but saves the contents in a token register. The contents of
the register are used in defining a macro that expands to the
verbatim listing.

\settowidth{\aebdimen}{\ttfamily\string\begin\darg{defineJS}[\anglemeta{tex/latex\_cmds}]\darg{\meta{Cmd}}}
\begin{dCmd}[commandchars=!()]{\aebdimen+2\fboxsep+2\fboxrule}
\begin{defineJS}[!anglemeta(tex/latex_cmds)]{!meta(Cmd)}
...
!anglemeta(JavaScript code)
...
\end{defineJS}
\end{dCmd}

\PD The \texttt{defineJS} environment takes two parameters, the
first optional. the required parameter is the command name to be
defined. Use the optional first parameter to modify the verbatim
environment, as illustrated in the example below.  The
\texttt{defineJS} is a complete verbatim environment: no escape, and
no comment characters are defined. You can use the optional
parameter to create an escape character.  You can pretty much use
any character you wish, \emph{except} the usual one `\verb+\+',
backslash.

\Example The following example illustrates the usage of the \texttt{defineJS} environment.
\begin{dCmd*}{.67\linewidth}
% Make @ the escape so we can
% demonstrate the optional parameter.
\def\HelloWorld{Hello World!}
\begin{defineJS}[\catcode`\@=0\relax]{\JSA}
var sum = 0;
for (var i = 0; i < 10; i++)
{
    sum += i;
    console.println("@HelloWorld i = " + i );
}
console.println("sum = "+sum);
\end{defineJS}
\begin{defineJS}{\JSAAE}
console.println("Enter the button area");
\end{defineJS}
\begin{defineJS}{\JSAAX}
console.println("Exiting the button area");
\end{defineJS}
\pushButton[\A {\JS{\JSA}}
    \AA{\AAMouseEnter{\JS{\JSAAE}}
        \AAMouseExit{\JS{\JSAAX}}}
]{myButton}{30bp}{15bp}
\end{dCmd*}
\newtopic The code of \cs{JSAAE} and \cs{JSAAX} are so simple, the \texttt{defineJS} environment
was really not needed. A simple \cs{newcommand} definition would have been sufficient.

\newtopic See \Nameref{lengthyJS} for an additional example of the use of the \texttt{defineJS} environment.

\appendixsubsection{Supported Key Variables}
%\addcontentsline{toc}{appendixsubsection}{\protect\numberline{}Supported Key Variables}

Below is a list of the keys supported for modifying the appearance
or for creating an action of a field. If the default value of a
key is empty, e.g., \verb+\Ff{}+, then that key does not appear in
the widget.  The \app{Acrobat} viewer may have a default when any
particular key does not appear, e.g. \verb+\W{}+ will be
interpreted as \verb+\W{1}+ by the viewer.

\newtopic In the past, the value of the \Cs{textColor} key must include the color model specification:
\begin{itemize}
\item \texttt{g} (for gray scale): a single number between 0 and 1; example, \verb!\textColor{.5 g}!
\item \texttt{rg}: Red Green Blue: a list of three numbers between 0 and 1 giving the components of color; for example \verb!\textColor{.1 .2 .3 rg}!
\item \texttt{k} Cyan Magenta Yellow [K]Black: a list of four numbers between 0 and 1 giving the components of the color according to the subtractive model used in most printers; for example \verb!\textColor{.1 .2 .3 .4 k}!
\end{itemize}
In this current version of \textsf{eforms}, the color model can be optionally included. The \textsf{eforms} package will supply the correct specification as a function of the number of arguments provided. Thus, the examples above can now be written as \verb!\textColor{.5}!, \verb!\textColor{.1 .2 .3}!, and \verb!\textColor{.1 .2 .3 .4}!.

\newtopic\textbf{\textcolor{red}{Note:}} Regarding the keys \Cs{textColor}, \Cs{BG}, \Cs{BC}, and \cs{Color}\footnote{Information regarding the \cs{Color}
key may be found in \hyperref[linkAnnots]{Section~\ref*{linkAnnots}},
page~\pageref*{linkAnnots}. The \cs{Color} key is more fully documented in
the rather comprehensive article
\textsl{\href{http://www.math.uakron.edu/~dpstory/aebblog/aeb_links.pdf}{Support
for Links in AeB/eForms}} posted on the
\href{\urlAcroTeXBlog}{AeB Blog}.},
beginning with \textsf{eforms} dated 2010/07/23 or later, \textsf{eforms}
now uses the \textsf{hycolor} package to process all color keys (listed
above); consequently, if the \textsf{xcolor} package is also loaded on
your system, you can use \emph{named colors} to specify color for the
\textsf{eforms} keys. For example, if the definition was made
\begin{Verbatim}[xleftmargin=\amtIndent]
\definecolor{myBlue}{rgb}{0.24,0.38,0.68}
\end{Verbatim}
then each of the following is valid: \verb!\textColor{myBlue}! (for specifying text color for text fields), \verb!\BG{myBlue}! (for specifying the background color of a field), \verb!\BC{myBlue}! (for specifying the border color of a field), and \verb!\Color{myBlue}! (for specifying the border color of a link).
