Ajax is a front technology in the Web. This technology provides a new model of internet interaction,and which greatly expands the capacity of Web applications. Something is introduced the Ajax technology works and analyze the main differences between the Ajax design patterns and traditional Web applications,on this basis,use Web page Ajax technique to realize the dynamic loading,this makes Web applications expedient response to user action,and avoid to send those who have not changed information frequently on the network. Compared to traditional Web application,Ajax technology enriches client-side performance capacity and greatly improves the user's experience. The reason is that Ajax technology can transmit data between client-side and server-side, and provides client-side and server-side with asynchronous communication capability and a powerful interactive performance. As a result, Ajax technology can reduce the amount of data transmission on network and balance the load between client-side and server-side. It shows that the Ajax technology can improve system performance and optimization of the user interface.%Ajax是Web领域的前沿技术,这种技术提供了新的互联网交互模型,并扩展了Web应用的能力.文中在介绍Ajax技术的工作原理、分析比较Ajax工作模式与传统Web工作模式区别的基础上,运用Ajax技术实现了网页的动态加载,用户的请求能更为迅捷地得到Web应用程序的回应.这样就避免了在网络上频繁地重复发送那些没有更新过的信息.相对于传统的Web应用,Ajax技术在丰富客户端的表现能力、改善用户体验中,表现了强大的交互性能.其原因在于Ajax技术实现了客户端与服务器间的数据通信,并提供了两者间异步通信的能力,因而降低了网络传输的数据量,均衡客户端与服务器间的负载.从而体现了Ajax技术提高系统效率与优化用户界面的优良性能.
