Read an Excerpt

Preface

For nearly 20 years, I have written the books I wished had already been written to help me learn or use a new technology. Whenever possible, I like to get in at the very beginning of a new authoring or programming environment, feel the growing pains, and share with readers the solutions to my struggles. This fourth edition of the JavaScript Bible represents knowledge and experience accumulated over five years of daily work in JavaScript and a constant monitoring of newsgroups for questions, problems, and challenges facing scripters at all levels. My goal is to help you avoid the same frustration and head scratching I and others have experienced through multiple generations of scriptable browsers.

While previous editions of this book focused on the then predominant Netscape Navigator browser, the swing of the browser market share pendulum currently favors Microsoft Internet Explorer. At the same time, Netscape has accomplished the admirable task of reinventing its own browser in light of rapidly advancing industry standards. As a result of both of these trends, this massively revised and expanded fourth edition treats both brands of browsers as equals as far as scripters are concerned. You hear my praise and dismay at various scripting features of both browser families. But empowering you to design and write good scripts is my passion, regardless of browser. Therefore, the book contains details about proprietary and standard implementations to equip you to choose the development path that best fits your content's audience. If you detect any bias of mine throughout this book, it is a desire, where possible, to write scripts that work on as many browsers as possible.

Organization and Features of This Edition

Because of the greatly expanded range of vocabularies that scripts may use in the latest browser versions, the biggest change to the structure of the book is in the reference portion. In this edition, you find a greater distinction between the document object model and core JavaScript language reference sections. This new division should help those readers who are primarily interested in only the JavaScript language (for use in other applications) find what they need more quickly. Here are some details about the book's structure.

    No CD-ROM in e-book!?

    The print version of this book ships with a CD-ROM which includes several chapters not included in the text. In addition, the CD is supposed to have lots of sample scripts and other materials referred to in the book. This is not just a "bonus", it is essential to using this book. Where is the digital equivalent of the CD? Without it, much of this book is worthless.

    "indoo" worst Customer Service I have ever had

    Ordered this book back on 19 Dec 2010, they shipped the wrong book on 22 Dec 2010. Asked for someone to call me about three weeks ago, but to this day even with me asking four time and giving them a number that I'm at 24/7 they have refused to call with no explaination. I do not know at this time if they are even going to ship me the book I ordered. They do not seem to understand simple English. I have stated a number of times that I still want the book I ordered. I was forced to return the book they sent in it's original package marked as "Return to Sender" because they were so slow in giving return instructions. I am sorry, but I will not pay to return a book that I did not order when the seller takes so long to give instructions for the return. THey also didn't mention that they would reimburse the return cost until three days after I had put in in the mail as mentioned above. All I can do is hope that I get the book I ordered or that they refund my money, But I want the book. At this point I wish that I could set my rating as ZERO STARS, but the system will not allow that.
