Ajax，即异步JavaScript与XML，目前是网络开发人员中*热门的编程技术之一。Ajax综合了大量技术，通过在浏览器中使用JavaScript来处理网络服务的响应，为创建基于XML或者JSON网络服务的交互式网络应用程序提供了坚实的基础。
《Ajax设计模式》为你展示了一些*佳实践方法，这些方法能够迅速提升你的网络应用程序开发项目。这本书分析了其他人如何成功地处理各种相互矛盾的设计原则，并将有用的信息直接传递给你。
本书中涉及的模式可以分为以下四种类型：
基本技术：检阅Ajax开发所需要的基础技术；编程实践：罗列为了确保Ajax应用程序的可维护性而由开发人员总结的编程技巧；功能和易用性：描述在进行Ajax应用程序开发时会碰到的各类用户界面，以及Ajax所提供的各种新功能 程序开发：解释用于监控、调试和测试Ajax应用程序的流程。
《Ajax设计模式》还将加快你对核心Ajax技术的掌握，其中包括XMLHttpRequest、DOM和JSON。本书的技术讨论还附有示例代码，以帮助你了解Ajax可以做什么和什么是Ajax做不到的。本书作为易于使用的参考手册，将帮助你设计
