Part of the Visual QuickStart Guide series, JavaScript for the World Wide Web is designed to get you up to speed with JavaScript as quickly as possible. The guide begins with a quick look at JavaScript in general and how to use it to detect browser versions, test for installed plug-ins, and perform other key steps for configuring and using it wisely. The book then moves on to the good stuff--manipulating images and adding dynamic effects to your pages. Next the authors show how to use JavaScript to fine-tune your frames, forms, and browser windows. By the end of the first half of the book, you"ll know how to add client-side dynamic data to your pages and manipulate cookies. The book also covers more advanced concepts, such as interacting Java applets and cascading style sheets. A chapter on debugging shows you the most common JavaScript errors and how to detect and fix them. The book also contains examples of real-world JavaScript usage, and a language reference section and companion Web site contain all the code. Throughout JavaScript for the World Wide Web, numbered step-by-step exercises--complemented by screen shots--make learning new techniques a snap. --Stephen W. Plain
