B/S架构WEB程序中AJAX异步传输技术的应用研究

Application Study on WEN AJAX Asynchronous Transmission Technology Based on B/S Architecture Model

基于B/S架构的WEB的应用程序实现人机交互的常见方式是页面请求,页面完整刷新过程令用户体验变差,服务器压力变大,程序响应速度变慢。利用AJAX异步传输技术实现页面的局部更新,可以提升程序交互的效率,提升程序界面的友好性。文章通过在线考试系统设计中的AJAX典型应用,介绍利用AJAX实现页面局部刷新的原理和方法。

Abstraet：a common way to realize human-computer interactions based on B/S architecture model WEB application programs is page request. The complete page refresh process reduces the effects of users＇ experience, increases the pressure of servers and slows down the speed of program response. The realization of part page refresh with application of AJAX asynchronous transmission technology can increase the efficiency of program interactions, offer friendlier program interface. The paper, based on typical application of AJAX in design of on-line test systems, introduces the principles and methods of the application of AJAX to realize part page refresh.
