A Simple Example using RegExp:
<html>
<head>
<script language='javascript'>
function CheckThis(obj) {
var strRegExp = /^[0-9]*$/;
if(!strRegExp.test(obj.value))
obj.value = '';
}
</script>
</head>
<body>
<p>Insert your data number here:</p>
<input type='text' id='test' size='10' value='' onkeyup='CheckThis(this);'/>
</body>
</html>
I don't know if this can help you, i hope.
