use alter function otherwise you'll have tyo foucs out of drop downwards , utilize text() inputs:

$('.first, .last, .country').change(function () { if ($('.first').text() == "" && $('.last').text() == "" && $('.country').val() == "") { $('.search').attr('disabled','disabled'); } else { $('.search').removeattr('disabled'); } });
