在JS中判断选中那个radio解决方案

在JS中判断选中那个radio
<asp:RadioButton ID="importanty" runat="server" Text="重要" GroupName="GR" OnCheckedChanged="Radio_Change" AutoPostBack="true"/>
   
  <asp:RadioButton ID="importantn" runat="server" Text="一般" GroupName="GR" Checked="true" OnCheckedChanged="Radio_Change1" AutoPostBack="true"/>

怎么在ＪＳ中判断选中那个，查看源码如下


 <td class="td2">
  <input id="ctl00_ContentPlaceHolder1_importanty" type="radio" name="ctl00$ContentPlaceHolder1$GR" value="importanty" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$importanty\',\'\')', 0)" /><label for="ctl00_ContentPlaceHolder1_importanty">重要</label>
   
  <input id="ctl00_ContentPlaceHolder1_importantn" type="radio" name="ctl00$ContentPlaceHolder1$GR" value="importantn" checked="checked" /><label for="ctl00_ContentPlaceHolder1_importantn">一般</label>
   
   
  </td>

支持使用Jquery，

<script type="text/javascript">
       $(":radio").each(function () {
           if ($(this).attr("checked") == "true" || $(this).attr("checked") == "checked")
           { }
       });
   </script>
