Amazon.com description: Product Description: This is a new kind of JavaScript book. It's not cut'n'paste, it's not a reference, and it's not an exhaustive investigation of the JavaScript language. It is about client-side, web focused, and task-oriented JavaScript.

JavaScript is a core skill for web professionals, and as every web professional knows, client-side JavaScript can produce all sorts of glitches and bugs. 'Practical JavaScript for the Usable Web' takes a two pronged approach to learning the JavaScript that you need to get your work done: teaching the core client-side JavaScript that you need to incorporate usable interactivity into your web applications, including many short functional scripts, and building up a complete application with shopping cart functionality.

When you have finished working with this book, you'll have a thorough grounding in Client-side JavaScript, and be able to construct your own client-side functionality quickly, easily, and without falling into any of the usability traps that this technology leaves wide open.
