Extending jQuery

Extending jQuery teaches you to build custom extensions to the jQuery library. It covers all the extension points within jQuery and provides guidelines and techniques on how to make use of them. You'll not only discover how to write plugins, but how to design them for maximum reuse. You'll also learn how to write new widgets and effects for jQuery UI. Along the way, you'll explore extensions in key areas including Ajax, events, animation, and validation.
