4. 在JS代码中使用WebServiceTableSort.WebServiceData.GetDataList(OnSuccessed)，GetDataList()函数是在web service中使用[WebMethod]定义的服务器方法，其中OnSuccessed为成功后所调用的方法，且带参数为GetDataList()函数的返回值
二、AJAX类：
1、在JS代码中直接使用服务器端的控件：var builder = new Sys.StringBuilder("");具体：http://www.asp.net/AJAX/documentation/live/ClientReference/Sys/StringBuilderClass/default.aspx
