jQuery, same function for multiple ids

i want to clear specified input if the value is not number. function works for one ID, but i want it to work for multiple. of course i can write function multiple times but i dont want to do that.

the following code gets effect only for input with id "d". i dont know how to identify other ids. can anyone help?

<input id="d" />

<input id="d2" />

<input id="d3" />

<script type="text/javascript">

$('#d,d2,d3').keyup(function(){

if($('#d,d2,d3').val() != "") {

    var value = $('#d,d2,d3').val().replace(/^\s\s*/, '').replace(/\s\s*$/, '');

    var intRegex = /^\d+$/;

    if(intRegex.test(value)) {}

    else {


    $(this).val('');

    }



}

});

</script>
