作为一名网站设计人员，您也许时常因为遇到以下情况而烦恼：用户只是移动了鼠标就要从服务器重载数据；尽管请求的服务很简单，用户却仍然需要长时间等待服务器的响应。无疑，Ajax技术能够帮助你减少这样的烦恼。Ajax中的异步技术能够让您设计的网站在变得更简洁的同时具有更敏捷的用户响应。
我们都知道，下一代的网站设计需要新的技术来指导；需要引入一些吸引人的、够炫的技术来支持我们完成设计。这就是本书能够提供给您的。阅读本书，一定会带给您许多的乐趣。首先，您可以在很短的时间内掌握如何使用JavaScript代码来向服务器提交异步请求。同时，更为有趣的是，您可以学习如何使用诸如动态HTML、XML、JSON、DOM等技术来解决开发过程中遇到的许多问题。毫无疑问，这是一本指导您进行异步开发的经典参考书籍。
本书和其他深入浅出系列书籍一样,使用许多有趣的视觉刺激来保持我们大脑思考的兴奋。在您读完书中第一章后，不但能够掌握一个基于Ajax的简单应用程序开发,而且还能够了解怎样让一个混乱的项目走上正轨。为了帮助读者解决问题，作者还为您准备了多达5张CD的资料作为参考。读完全书，您会惊奇的发现那些繁琐笨拙的网站开发技术早已随风而去，展现在我们面前的是一个崭新的技术境界。
