Answer 1

把输出的html代码贴一下，看这个代码，似乎没有问题，最有有可能是前两句出错了。

没有问题的。

Answer 5

你ID怎么会变成这个id="dg_keys_ctl05_Label2" 你的ID应该是r
JS取值用getElementById
你要用name JS应该是
 var a = document.getElementsByName("r"); 
      for(i=0;i <a.length;i++) 
      {  
                      if(a[i].checked)  
                      { 
                        alert(a[i].attributes.getNamedItem('value').nodeValue); 
                      } 
      }  request.form["r"]得不到应该是你没提交

Answer 6

你ID怎么会变成这个id="dg_keys_ctl05_Label2" 你的ID应该是r  + i

Answer 7

我开始白扯了 哈哈
JS得的到
request.form["r"]得不到应该是你没提交

Answer 8

var bookList = $("dgGroupForMove");//dgGroupForMove GridView的ID
var valueId;
var radList = bookList.getElementsByTagName("input");
for(var i=0;i<radList.length;i++)
{
if(radList[i].checked == true)
{
valueId = radList[i].value;
}
}
