about the technology

jQuery, the most popular JavaScript library, helps make client-side scripting of HTML easy. It offers many built-in abilities to traverse and alter the DOM, but it can't do everything. Fortunately, you can tap into jQuery's numerous extension points to create your own selectors and filters, plugins, animations, and more. This book shows you how.
