主要内容:
JavaScript is a platform-independent scripting language that you can use to control many features and
automate many tasks in Adobe® applications. Scripting is easier to learn and use than many other kinds of
programming, and provides a convenient way of automating repetitive tasks or extending applications to
provide additional tools for other users.
If you are new to scripting, see Adobe Creative Suite: Introduction to Scripting, which introduces basic
scripting concepts and describes different scripting languages that are available, including JavaScript.
JavaScript and other scripting languages are object-oriented, and this book also describes the basic
concepts of object-oriented programming and document object models.
Each application that supports JavaScript also provides an application-specific Scripting Guide that
introduces the object model for that application, and reference material for the objects. This
document provides information about the JavaScript features, tools, and objects that are common to
all Adobe applications that support JavaScript.
This document does not teach JavaScript. If you are familiar with scripting or programming in general,
but unfamiliar with JavaScript, see publicly available Web resources and documents, such as:

ExtendScript overview
Adobe provides an extended implementation of JavaScript, called ExtendScript, that is used by many
Adobe applications that provide a scripting interface. In addition to implementing the JavaScript
language according to the ECMA JavaScript specification, ExtendScript provides certain additional
features and utilities.
This document describes JavaScript modules, tools, utilities, and features that are available to all
JavaScript-enabled Adobe applications.
N OTE : Some modules, and features of some modules, are optional. Check the product documentation for
each application for details of which modules and features are implemented.
Example code
The Adobe ExtendScript SDK, which contains this document, also contains a set of code samples that
demonstrate how to use features of ScriptUI, interapplication communication, and external
communication. This book refers to these samples by name for illustration of concepts and techniques.
You can download the SDK from Adobe Developer Center, http://www.adobe.com/devnet/scripting/.
