高效的Web性能提升机制研究

An Efficient Mechanism to Accelerate Efficiency of Web

一次性加载技术导致B/S项目的页面响应时间激增,严重影响到了用户的操作体验。为了避免这类问题,本文提出了优化级联的下拉列表方法,分级的加载数据项,减少无效的数据传送,可以在不更新整个页面的情况下重新加载数据;给出了通过AJAX和Servlet配合,实现无刷新的多级级联下拉列表的实现案例。性能分析和实验结果证明:该方法减少了无效数据的传送,增强了用户体验和页面的响应速度,提高了系统性能。

One - time loading technique of B/S leads to more cost of response time, and influence the user to experience. To avoid it, this paper puts forward the dropdown list method to classify the loading data items, to reduce invalid data transfer, and it can reload the data without updating the whole pages. With the combination of AJAX with Servlet. it can realize a set of cascade dropdown list without refreshing the surface. This method has reduced the invalid data transmission, enhance the user＇ s experience and the response speed of the page, and improve the system performance.
