利用Ajax与ExtJS改善用户体验

随着Web技术的不断发展,传统的B/S"瘦客户端,胖服务器"结构已不能满足用户正常体验和实时交互要求。Ajax技术可以实现用户异步请求,减轻网络负载,ExtJS作为Ajax的RIA框架,使得界面构建更加容易。从Ajax原理,ExtJS在OA型系统中的应用及性能调优出发,设计实现了三农电子商城后台管理系统,并探讨了ExtJS在基于B/S结构的OA型电子商务系统中对用户体验的改善。系统界面美观,操作方便,开发效率高,维护规范,可以满足用户正常体验和实时交互需求。

Improving user experience by Ajax and ExtJS

With the development of Web technology,traditional B/S structure of "thin client and rich server" cann’t meets the demands of normal user experience and strenuous timely communication.Ajax can realize the asynchronized request of user and reduce the burden of network.At the same time,ExtJS plays the role of RIA frame,and it is esaier to build gorgeously interfaces.This paper introduces the principle of Ajax,the application of framework ExtJS in the OA-based system and the optimization of the performance of Web server.This paper has designed and implemented a background management system of E-commerce,and discusses how to improve the user experience by using the ExtJS framework in the OA-based electronic commerce systems which based on B/S structure.The system has many advantages such as the distinct interface and the easy manipulation.Moreover,the system has developing efficiency and standard maintenance.Further more,it can meet the demands of normal user experience and strenuous timely communication.
