Summary

A good web development framework anticipates what you need to do and makes those tasks easier and more efficient; jQuery practically reads your mind. Developers of every stripe-hobbyists and professionals alike-fall in love with jQuery the minute they've reduced 20 lines of clunky JavaScript into three lines of elegant, readable code. This new, concise JavaScript library radically simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages. jQuery in Action, like jQuery itself, is a concise tool designed to make you a more efficient and effective web developer. In a short 300 pages, this book introduces you to the jQuery programming model and guides you through the major features and techniques you'll need to be productive immediately. The book anchors each new concept in the tasks you'll tackle in day-to-day web development and offers unique lab pages where you immediately put your jQuery knowledge to work.
