http://www.mattkruse.com/javascript/validations/
Here is the code
<script language="JavaScript" type="text/javascript">
var frmvalidator = new Validator("myform");
frmvalidator.addValidation("Phone","maxlen=3");
frmvalidator.addValidation("Phone","numeric");
</script>
Sample using Regex
function fnValidate()
{
var val=document.Form1.txt.value;
alert(val);
var re = new RegExp("^[0-9]{3}$");
if(val.match(re))
{
alert("OK");
}
else
{
alert("NOT OK ");
}
}
