Try this code and make it some modifications according your proper requirement

<script type="text/javascript">
$(document).ready(function () {
$('input[numeric]').keyup(function () {
var d = $(this).attr('numeric');
var val = $(this).val();
var orignalValue = val;
val = val.replace(/[0-9]*/g, "");
var msg = "Only Integer Values allowed.";
if (val != '') {
orignalValue = orignalValue.replace(/([^0-9].*)/g, "")
$(this).val(orignalValue);
alert(msg);
}
});
});
</script>

jQuery has an isnumeric() function already, so you could use that to do the check! Here's an example of how to use it as part of your client side validation:

if(!$.isNumeric($('#elementId').val())) {
    // show an error
}
