    Try this: 

     <HTML>
       <HEAD>
       <SCRIPT type="text/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>
