基于Ajax技术的web模型在网络课程开发中的应用研究

Study on Ajax-based Web Model Applying to Network Course Development

Ajax是web2.0标准的核心技术，基于Ajax的web模型通过在客户端建构中间层，实现了页面表现与应用逻辑的分离，并支持用户操作与服务器响应的异步化。文章简要阐述了Ajax模型的核心概念、体系结构和异步交互机制，并通过《电子技术实验》网络课程的开发实践，探讨了其在异步交互web环境中的应用，发现Ajax技术能改变传统web应用模型中[点击--等待]的不连贯行为方式，显著提高学习者的交互体验。

Ajax is the key technology of web2.0. Ajax-based web model has separate the view layer with business logical layer， and support asynchronous-rization between consumer operation and the server response owing to the middle layer constructed in consumer side. The core concept， system structure and asynchronous principle of the Ajax-based web model is discussed， and the network course of electron technology experiment implemented by Ajax technology being able to change the tradition web behavior of click-waiting ， notable improve learner's interactive experience in study.
