Try something like that

$('.totalontarget, .totalofftarget').on('keyup', function(e){
    var max = $(this).parent().parent().find('.totalofservices').val();

        if ($(this).val() > max) {
           alert('Value more that ' + max);
           e.preventDefault();
        }
});

Check this out : https://jqueryvalidation.org/. Anyway, even if client validation could look more user-friendly, it should be implemented also in the server side.
