JavaScript Application Cookbook

Appendix A. JavaScript Reference

This appendix contains JavaScript syntax reference in the following areas:

• Objects, methods, and properties

• Top-level functions and properties

• Event handlers

In general, JavaScript has a three-pronged structure: core, client-side, and server-side. Core JavaScript refers to those features that can be used on both the client and server sides. Client- and server-side JavaScript includes core JavaScript plus extensions of each particular environment. For example, client-side JavaScript contains the window and the document objects, something the server would have no use for. Similarly, server-side JavaScript contains the File object.

The material here is current as of client-side JavaScript 1.3 and core JavaScript 1.4. Everything in the following pages comes straight from the Netscape sites:

You can find Microsoft Jscript resources at:

Keep this as a handy quick reference, but always refer back to the Netscape and Microsoft material for the latest material.
