问题是  ：当我点击提交的时候 我想知道那个按钮被选中工商银行  ICBC  建设银行 CCB  等等其他
想给他们赋值  选中的时候把值取出来  

Answer 1

给他们分到相同的组，取组的，checked值。

Answer 2

<asp:RadioButton ID="RadioButton1" Checked="true" runat="server" GroupName="Color" Text="Red" />
<asp:RadioButton ID="RadioButton2" runat="server" GroupName="Color" Text="White" />這個是分組，GroupName
if(RadioButton1.checked = true)
{
...
}這個是判斷

Answer 3

以上If內"=”改為 "=="一般考慮用RadioButtonList控件
因為它有屬性可以直接獲取選到那項的值：[code=C#][/
RadioButtonList1.SelectedValue == "XXX銀行code]"

Answer 4

RadioButtonList1有text和value值，你取设定value值，就可以实现你点击的是哪个了！

Answer 5

 function getvalue()
        {
        var b=document.all.rbtid.length
        var a=document.getElementById("rbtid").cells.length; 
        //alert(b);结果为5
        //alert(a);结果为4
        //for(var i=0;i<b-1;i++)这样也行
        for(var i=0;i<a;i++)
        {
          var ss="rbtid_"+i;
          var aa=document.getElementById(ss).value;
          //if(eval('document.all.rbtid_'+i).checked==true) //这样也行 eval()函数能将数据符串转成js运行
          var bb=document.getElementById(ss);
          if(document.getElementById(ss).checked) //注意checked不能写成Checked，要不然不成功
           {
                  alert(aa);
                  break;
           }      
        
        }
        }
类似的改改就可以了
