Ajax核心技术及其研究应用

Ajax Core Technology and Its Research Application

介绍了一种新的Web应用程序开发技术——Ajax,该技术通过综合JavaScript、XHTML和CSS、DOM、XML和XSTL、XML Http Request等多种技术,形成一种新的设计方式,使用户与服务器实现异步通信,构建更为动态和响应更灵敏的Web应用程序。其中,JavaScript构造的XML Http Request对象是Ajax的核心,通过该对象浏览器能实现与服务器的异步通信。将结合实例说明Ajax在实际工程项目中的应用。

This paper introduces a kind of new technolngy-Ajax,which used to develop Web application program. This technology forms a kind of new design mode through synthesizes many kinds of technologies such as JavaScript, XHTML, CSS and DOM, XML, XSTL, XMLHttpRequest and so on, it realizes asynchronous communication between the user and the server, constructs more dynamic and respond sensitive Web application procedure. Among them, the XMLHttpRequest object constructed by JavaScript is the core of Ajax, it can realize the asynchronous communication between the browser and server. The application of Ajax in the actual engineering project is elaborates with the example in this paper.
