基于AJAX的数据分页的设计与实现

Design and implementation of data paging based on AJAX

针对传统数据分页存在用户等待时间较长的问题,提出一种基于AJAX的数据分页方法,并成功地在设备管理系统的查询模块上得到应用,实际应用的结果表明,在现有的Web应用中采用AJAX技术,能减轻服务器压力,提高系统的响应速度,减少用户的等待时间。首先对比了传统Web和标准AJAX的交互过程,接着介绍了A-JAX概念及核心技术,同时给出了结合AJAX和J2EE技术实现数据分页的例子。

A method of data paging based on AJAX is proposed to solve the problem that the user＇s waiting time is too long in the traditional data paging. The application is successfully made to inquiry module of the Equipment Manage- ment System （EMS）. The result shows that the application of AJAX to the Web releases the pressure of the server, accelerates the system response speed and cuts down the user＇ s waiting time. The interactive processes between the traditional Web and the standard AJAX are compared. The concept and core technology of AJAX is introduced and an example to implement the data paging by using the combination of AJAX and J2EE is presented.
