Add an event to a textbox at runtime

Hello,

I am working on a site in which I must make a text box that cannot allow numbers to be entered. My only problem is that I cannot insert an onKeyPress or onKeyDown event into the input tag itself, I must do this elsewhere in my code.

Any help with this would be appreciated

Thanks,

If this is any help here is what I have so far, this page does exactly what I want it to do, the onKeyPress event must be somewhere in the script though

<HTML>
<HEAD>
<SCRIPT language=Javascript>
<!--

function isNumberKey(evt)
{

     var charCode = (evt.which) ? evt.which : event.keyCode
//alert(charCode);
     if (charCode > 31 && (charCode < 48 || charCode > 57))
        return false;

     return true;
  }





  //-->

</SCRIPT>
</HEAD>
<BODY>

<p>Numbers Only</p>
<INPUT name="box1" onkeypress="return isNumberKey(event)" type="text">

</BODY>
</HTML>
