    I found this, may be it works for you.

    Code:
    <HTML>
  <HEAD>
  <SCRIPT language=Javascript>
      <!--
      function isNumberKey(evt)
      {
        var charCode = (evt.which) ? evt.which : event.keyCode
        if (charCode > 31 && (charCode < 48 || charCode > 57))
            return false;
 
        return true;
      }
      //-->
  </SCRIPT>
  </HEAD>
  <BODY>
      <INPUT id="txtChar" onkeypress="return isNumberKey(event)" type="text" name="txtChar">
  </BODY>
</HTML>
