电子书免费下载 Ajax: The Definitive Guide

Is Ajax a new combination of technologies, or the same old stuff web developers have been using for years? Both, actually. Ajax builds on older technologies and techniques but reaches a tipping point where the results are new. Ajax: The Definitive Guide gives you a leg up on this new stage of web development by teaching you how tried-and-true web standards -- like JavaScript, XML, CSS, DOM, and XHTML -- not only make Ajax possible, but why developing with them is faster, easier and cheaper.

Ajax: The Definitive Guide demonstrates how to build browser-based applications that function like desktop programs, using sophisticated server-aware approaches that give users information when they need it. You'll explore what can be done with Ajax to enhance sites and give them a Web 2.0 feel, and how additional JavaScript enhancements can turn a web browser and web site into a true application.

The book also explains:

Server-side backend components and how to connect them to user interfaces in the browser

Web application frameworks such as Struts, Django, Ruby on Rails, and Zend

By offering web developers a much broader set of tools and options, Ajax is giving developers a new way of creating content on the Web, while throwing off the constraints of the past.
