ajax如何调用本页数据源不用一般处理程序

近来我发现我一些同事。在用ajax时,用数据源,都喜欢重新新建一个页面.其实我是很不喜欢这种模式,主要原因,一是后期维护麻烦,还要去找哪些页面,二是不能调用一些本页原有的数据方法.因此我在这里做了一个测试的案例。如下

CS代码

 1 using System;
 2 using System.Data;
 3 using System.Configuration;
 4 using System.Collections;
 5 using System.Web;
 6 using System.Web.Security;
 7 using System.Web.UI;
 8 using System.Web.UI.WebControls;
 9 using System.Web.UI.WebControls.WebParts;
10 using System.Web.UI.HtmlControls;
11 using System.Web.Services;
12 
13 public partial class TestAjax : System.Web.UI.Page
14 {
15     protected void Page_Load(object sender, EventArgs e)
16     {
17         string methor = Request["act"];
18         if (!string.IsNullOrEmpty(methor))
19         {
20             this.GetType().GetMethod(methor).Invoke(this, null);
21         }
22 
23     }
24 
25     public void GetVal()
26     {
27         string val = "getVal 方法获取参数" + Request["arg"];
28         Response.Clear();
29         Response.Write(val);
30         Response.End();
31     }
32 
33 }

aspx页面
