首先，Radiolist控件默认Render后最外面是个<table>，好，看代码，传统方式:
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-
2
3 transitional.dtd">
4 <html xmlns="http://www.w3.org/1999/xhtml">

6 <head>
7 <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
8 <title>test</title>
9 <script type="text/javascript">
10 function test2()
11 {
12 var rbltable = document.getElementById("rl");
13 var rbs= rbltable.getElementsByTagName("INPUT");
14 for(var i = 0;i<rbs.length;i++)
15 {
16 if(rbs[i].checked)
17 {
18 var value=rbs[i].value;
19 alert(value);
20 //Js_open(b
)
21 }
22 else
23 {
24 //Js_open(a)
25 }
26 }
27 }

39 <label>发</label><input id="rl_2" name="rl$tt" type="radio" value="2" />
40 </td>
41 </tr>
42 </table>
43 <input name="b1" onclick="test2();" type="button" value="确定" />

再看下JQuery，如何实现，非常简单:
