The Application Study Of Ajax Technology In The Web System

With the rapid development of Internet and web applications, the traditional web applications have become increasingly difficult to meet the needs of users. The traditional web application is strong impact by the development of the concept of Web2.0 and RIA.This thesis analyses model of the traditional web application and its shortcomings and points out the synchronous interactive process of the traditional web application. This thesis analyses the principle and advantages of the Ajax technology and make the description of the characteristics of asynchronous interaction. Besides, analysing its own shortcomings and proposing solutions to the shortcomings。It can make web applications asynchronous interaction, thereby greatly enhancing the user experience and web operational efficiency. The new technology opens up a new development direction for the web applications.Based on research and application of the Ajax technology, Through the web system of practical application, testing Ajax technology in the web system of the actual results and solving the problems of large amounts of data and information server interaction. It provides a solution to large amounts of data for the application of environmental systems development. This thesis designes and develops the actual case—based on Ajax technology of the"digital campus"online exam system. The whole system is perfect combination of Ajax technology, greatly improving the system performance, doing a very good attempt to work for the development of other similar systems.The development of online examination system provides a certain amount of reference for the campus network in the development of web applications.
