Acrobat JavaScript Contexts
Acrobat JavaScripts can be applied at a variety of levels:
Each of these levels represents a context in which processing occurs, which affects when
the scripts are loaded and how they are accessed inside and outside documents.
The placement of a JavaScript at a given level also determines its reusability. Folder level
scripts are available within all documents, document level scripts are available to all fields
within a given document, and field level scripts are visible only to the fields with which they
are associated.
For more information, see the Acrobat JavaScript Scripting Guide .
Plug-ins
Plug-ins are dynamically-linked extensions to Acrobat or Adobe Reader. They can hook into
the user interface in a number of ways and can register to be called when a variety of
events occur in the application.
A plug-in is a program written in ANSI C/C++ that uses the Acrobat public APIs. It adds
functionality to Acrobat Professional, Acrobat Standard, or Adobe Reader. A plug-in
program file goes into a
Plug_ins folder or directory and is initialized during Acrobat or
Adobe Reader startup.
folder level These scripts contain variables and functions that may be generally
useful to the Acrobat application, and are visible from all documents.
document level These scripts are function and variable definitions that are generally
useful to a given document, but are not applicable outside the
document.
field level These scripts can be associated with any component within a
document. In the case of dynamic XML forms, such scripts are only
visible to that component and execute as actions or events. See
“XML
Forms” on page 79 .
batch level These scripts can be applied to a collection of documents, and
operate at the application level.
