Ajax原理、性能及其应用

The principle,performance and application of Ajax

Ajax是Web应用的一个新方向,它并不是一项技术,实际上是几项技术合在一起形成的一个新方法。本文首先从原理上对Ajax进行了阐述,分析了其与传统Web方式的不同之处,然后对Ajax的性能进行了论述,并给出了一组实验数据用以对比分析传统Web方式的性能,由此实验结果论述Ajax应用模型性能的优越性,最后阐述了Ajax的适用场景并总结了其缺点及局限性。

Ajax is a new approach in the web application,which is not a single technology,but a new approach by combining some kinds of technology.This paper first make a description from principle,analyze the difference with the classic Web approach,then discuss the performance of Ajax,and offer a group of experiment data to compare and analyze the performance of the classic Web application model,then with the result,discussing the advantage of the Ajax application model,at last enumerate the appropriate scene to Ajax.
