About the Authors
Danny Goodman is the author of numerous critically acclaimed and best-selling books, including The
Complete HyperCard Handbook, Danny Goodman’s AppleScript Handbook, Dynamic HTML: The Definitive Reference, and JavaScript & DHTML Cookbook. He is a renowned authority on and expert teacher of computer scripting languages. His writing style and pedagogy continue to earn praise from readers
and teachers around the world.
Michael Morrison is a writer, developer, toy inventor, and author of a variety of books covering
topics such as Java, C++, Web scripting, XML, game development, and mobile devices. Some of
Michael’s notable writing projects include Faster Smarter HTML and XML, Teach Yourself HTML
& CSS in 24 Hours, and Beginning Game Programming. Michael is also the founder of Stalefish
Labs (www.stalefishlabs.com), an entertainment company specializing in unusual games, toys, and
interactive products.
Paul Novitski has been writing software as a freelance programmer since 1981. He once taught
himself BASIC in order to write a machine language disassembler so that he could lovingly hack
Wang’s OIS microcode. He has focused on internet programming since the late ’90s. His company,
Juniper Webcraft, produces HTML-strict websites featuring accessible, semantic markup, separation
of development layers, and intuitive user interfaces. He knows the righteousness of elegant code, the
poignancy of living on the bleeding edge of wilderness, the sweet melancholy of mbira music, and the
scorching joy of raising twin boys.
Tia Gustaff Rayl is a consultant who does development and training in database and Web
technologies. Most recently she has published courseware for XHTML, CSS, JavaScript, and SQL.
It comes as no surprise to those who know her that she began her software career with degrees in
English and Education from the University of Florida. As is usual for most newcomers to the field,
her introduction to computing was maintaining software. She went on to a long-standing career
in the software industry in full life cycle system, application, and database development; project
management; and training for PC and mainframe environments. In the mid-nineties she worked on
early Web-enabled database applications, adding JavaScript to her repertoire. She continues to take on
development projects to maintain her code-slinging skills. If she had any spare time (and money) she
would go on an around-the-world cruise with her husband and two dogs.

Introduction
This seventh edition of the JavaScript Bible represents knowledge and experience accumulated
over fifteen years of daily work in JavaScript and a constant monitoring of newsgroups for
questions, problems, and challenges facing scripters at all levels. Our goal is to help you avoid
the same frustration and head-scratching we and others have experienced through multiple generations
of scriptable browsers.
While the earliest editions of this book focused on the then-predominant Netscape Navigator browser,
the browser market share landscape has changed through the years. For many years, Microsoft took a
strong lead with its Internet Explorer, but more recently, other browsers that support industry standards
are finding homes on users’ computers. The situation still leaves an age-old dilemma for content
developers: designing scripted content that functions equally well in both standards-compliant and
proprietary environments. The job of a book claiming to be the ‘‘bible’’ is not only to present both
the standard and proprietary details when they diverge, but also to show you how to write scripts
that blend the two so that they work on the wide array of browsers visiting your sites or web applications.
Empowering you to design and write good scripts is our passion, regardless of browser. It’s true
that our bias is toward industry standards, but not to the exclusion of proprietary features that may
be necessary to get your content and scripting ideas flowing equally well on today’s and tomorrow’s browsers.
Organization and Features of This Edition
Like the previous three editions of the JavaScript Bible, this seventh edition contains far more information than can be printed and bound into a single volume. The complete contents can be found in
the electronic version of this book (in PDF form) on the CD-ROM that accompanies the book. This
edition is structured in such a way as to supply the most commonly needed information in its entirety
in the printed portion of the book. Content that you use to learn the fundamentals of JavaScript and
reference frequently are at your fingertips in the printed version, while chapters with more advanced
content are in the searchable electronic version on the CD-ROM. Here are some details about the book’s structure.
Part I: Getting Started with JavaScript
Part I of the book begins with a chapter that shows how JavaScript compares with Java and discusses
its role within the rest of the World Wide Web. The web browser and scripting world have
undergone significant changes since JavaScript first arrived on the scene. That’s why Chapter 2 is
devoted to addressing challenges facing scripters who must develop applications for both single- and
cross-platform browser audiences amid rapidly changing standards efforts. Chapter 3 introduces some
tools you can use to compose your pages and scripts, while Chapter 4 delves into the nitty-gritty of
how to use JavaScript to run in a wide variety of browsers.
Part II: JavaScript Tutorial
All of Part II is handed over to a tutorial for newcomers to JavaScript. Ten lessons provide you with
a gradual path through browser internals, basic programming skills, and genuine browser scripting,
with an emphasis on industry standards as supported by most of the scriptable browsers in use today.
Exercises follow at the end of each lesson to help reinforce what you just learned and challenge you to
use your new knowledge (you’ll find answers to the exercises in Appendix D, on the CD-ROM). The
goal of the tutorial is to equip you with sufficient experience to start scripting simple pages right away
while making it easier for you to understand the in-depth discussions and examples in the rest of the book.
Part III: JavaScript Core Language Reference
Reference information for the core JavaScript language fills Part III. In all reference chapters, a compatibility chart indicates the browser version that supports each object and object feature. Guide words near the tops of pages help you find a particular term quickly.
Part IV: Document Objects Reference
Part IV, the largest section of the book, provides in-depth coverage of the document object models as
implemented in today’s browsers, including the object used for modern Ajax applications. As with the
core JavaScript reference chapters of Part III, these DOM chapters display browser compatibility charts
for every object and object feature. One chapter in particular, Chapter 26, contains reference material
that is shared by most of the remaining chapters of Part IV. To help you refer back to Chapter 26
from other chapters, a shaded tab along the outside edge of the page shows you at a glance where
the chapter is located. Additional navigation aids include guide words near the tops of most pages to
indicate which object and object feature is covered on the page. Note that the Objects Reference begun
in Part IV of the book continues in Part VI on the CD, with an additional 13 chapters of reference material.
Part V: Appendixes
Appendix A offers a JavaScript and Browser Objects Quick Reference. Appendix B provides information about using the CD-ROM that comes with this book, which includes numerous bonus chapters and examples.
Part VI: Document Objects Reference (continued)
Beginning the portion of the book that resides only the accompanying CD, Part VI continues the document objects reference discussios that begin in Part IV by providing an additional 13 chapters of reference material.
Part VII: More JavaScript Programming
Chapters 46–51 discuss advanced JavaScript programming techniques, including data-entry validation,
debugging, and security issues.
Part VIII: Applications
The final ten chapters of the book, available only on the CD-ROM, feature sample applications that
cover the gamut from calendars to puzzles.
Part IX: Appendixes (continued)
The final three appendixes provide helpful reference information. These resources include a list of
JavaScript reserved words in Appendix C, answers to Part II’s tutorial exercises in Appendix D, and
Internet resources in Appendix E.
