This works for me...
<html>
<head>
<script language="javascript" type="text/javascript"
src="/usr/share/javascript/jquery/jquery.js"></script>
<script language="javascript" type="text/javascript">
$(function() {
$('#numbersonly').keypress(
function(event) {
return ((event.which >= 48) && (event.which <= 57));
}
);
});
</script>
</head>
<body>
<input id="numbersonly" name="first_name"/>
</body>
</html>
