WebService编程笔记（一）

一、将WebService方法与AJAX联系起来：

0. Web.Config文件中要加入一些东东（具体再分析）

1. 定义一个webservice页面.asmx
[System.Web.Script.Services.ScriptService] 取消屏蔽

2. 其中的方法应该为public且增加属性[WebMethod]  <form id="form1" runat="server">
 
3. 在Aspx页面中，加入AJAX控件如下，并在ServiceReference Path中链接web service页面，如下：

代码

     < form  id ="form1"  runat ="server" >
     < div >
     < asp:ScriptManager  ID ="ScriptManager1"  runat ="server" >
     < Services >
     < asp:ServiceReference  Path ="WebServiceData.asmx"   />
     </ Services >
     </ asp:ScriptManager >
     </ div >
     </ form >

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
