本文主要针对目前网站上常用的查询系统所存在的某些常见问题而提出了一种新的查询设计思路,这种新的设计思路主要是在客户端利用JavaScript脚本语言对用户设置的查询条件进行预处理,让用户设置的条件以两种形式出现在系统中,一种形式方便方便用户阅读和理解,另一种形式用于真正的数据查询;此外,通过脚本语言将用户设置的查询条件保存于页面上列表中,用户可以随意组合现有的条件形成更为复杂的查询条件;同时用户也可以在列表中随意选择某个条件执行数据查询。
In this paper, aiming at some common problems existed in the commonly used query systems on the website, a new query design idea is proposed. This new design idea mainly uses the JavaScript scripting language to query the user-set query conditions Pretreatment, allowing users to set the conditions appear in two forms in the system, a form of convenience for users to read and understand, and the other for the real data query; In addition, the script language will be set by the user to save the query In the list on the page, users can freely combine the existing conditions to form more complicated query conditions; at the same time, the user can also select a certain condition in the list to execute the data query.
