推荐答案

我不是100％确信这会起作用，但这是一个主意:

I''m not 100% sure this will work, but it is an idea:

function doSomething(){
   var jd = document.getElementById('<%=TextBox2.ClientID %>');
   if(jd.value == ""){ clearRadioButtonList(); }
}

function clearRadioButtonList() {
      var elementRef = document.getElementById('<%= RadioButtonList1.ClientID %>');
      var inputElementArray = elementRef.getElementsByTagName('input');

      for (var i = 0; i < inputElementArray.length; i++) {
         var inputElement = inputElementArray[i];

      inputElement.checked = false;
   }
   return false;
}
