jQuery is a JavaScript library that helps web developers create JavaScript applications that work well in any browser. This book demonstrates how to use jQuery to reduce the amount of code you need to write and reduce the amount of testing that is required. Youll see how separation of presentation (CSS), markup (XHTML), and script (JavaScript and Ajax) in web pages is a crucial direction in web development for creating maintainable, accessible, cost-effective web sites. The featured full-color code syntax highlighting provides you with a visual reinforcement so you can see the various pieces and parts that make up each line and section of code for each language.

jQuery allows you to do more in the world of dynamic web applications, with less code and fewer errors. It reduces the amount of JavaScript programming to only a few lines of code while making your JavaScript more intuitive and attractive to work with. At the same time, jQuery makes it easier to manipulate CSS from JavaScript by allowing you to set style for one or many elements at once.

With this unique, project-oriented book, author Richard York teaches even the most novice of JavaScript users how to quickly get started utilizing the JavaScript jQuery Library to decrease the amount of code that needs to be written and tested. A four-color code syntax highlighting system provides a visual reinforcement and allows you to see the nuts and bolts that comprise each line and section of code. With this helpful guide and hands-on exercises, you'll be able to put jQuery to work for you and avoid having to write code from scratch.
