1、主要的业务逻辑就是客户要求点击添加按钮能够将参加会议的参加人添加进去，然后点击删除按钮能够将其删掉，但是前提是点击添加之后不仅要在web前段加上所添加的那个人，而且还有在缓存中保存所添加的人员。因为点击添加按钮不是要和服务器端做交互。点击提交审批的时候才是要和服务器端做交互。部分代码如下：

难点：本操作的难点就是拼接字符串，因为所添加的用户是动态添加的，动态添加好之后还要往缓存里面放一份。当append的时候先判断缓存里面有没有，如果没有的话，就去品字符串拼一个DataTable出来，如果缓存里面有的话，先读取缓存里面的内容，在将添加的参加者拼接到DataTable里面。然后动态的显示。在asp.net中有DataTable，但是在jquerymobile中没有现成的DataTable,需要自己动手去拼字符串，拼出DataTable，这样才能达到我们想要显示的效果。
