JavaScript is essential for creating modern, interactive Web sites. But, unlike HTML and CSS, JavaScript is a true programming language with complex rules that are challenging for most Web designers to learn. In JavaScript: The Missing Manual, bestselling author David McFarland teaches you how to use JavaScript in sophisticated ways -- even if you have little or no programming experience.In a clear, entertaining way, the book starts out by teaching you how to build a basic JavaScript program. Then, once you've mastered the structure and terminology, you'll learn how to use advanced JavaScript tools to add useful interactivity to your sites quickly and painlessly, rather than scripting everything from scratch.To jump-start your progress, the book offers several "living examples" -- step-by-step tutorials for building Web site components with JavaScript using raw materials, such as graphics and half-completed Web pages, that you can download from the book's companion Web site.
