The Book of JavaScript teaches readers how to add interactivity, animation, and other tricks to their web sites with JavaScript. Rather than provide a series of cut-and-paste scripts, thau! takes the reader through a series of real world JavaScript code with an emphasis on understanding. Each chapter focuses on a few important JavaScript features, shows how professional web sites incorporate them, and takes readers through examples of how they might add those features to their own web sites. This thoroughly updated 2nd edition includes new chapters on Ajax, revised appendices, and new examples throughout. Summary sections and assignments close each chapter, making the book perfect for use in college courses or independent study.
