This book teaches readers how to add interactivity, animation, and other tricks to their websites with JavaScript. Rather than provide a series of cut-and-paste scripts, thau! takes the reader through real-world JavaScript code examples with an emphasis on understanding. Each chapter focuses on a few important JavaScript features, shows how professional websites incorporate them, and shows readers how they might add those features to their own websites. This thoroughly updated and completely reworked second edition includes coverage of Ajax, revised appendices, and new examples throughout.
