推荐答案

使javascript函数如下:

make a javascript function like:

<Script type="text/javascript">
function clearText(cntId) {
  var cnt = document.getElementById(cntId);
  cnt.value ="";
  return false;
}
</script>

then on your submit button attach a client side event

<asp:Button id='btnSubmit' Text='Submit' onClientClick='clearText("<%this.lblLable.ClientId%>");' .... />
