You can easy add sweet alert in your script by adding code (example from warning button):

    $('.demo3').click(function () {
        swal({
            title: "Are you sure?",
            text: "You will not be able to recover this imaginary file!",
            type: "warning",
            showCancelButton: true,
            confirmButtonColor: "#DD6B55",
            confirmButtonText: "Yes, delete it!",
            closeOnConfirm: false
        }, function () {
            swal("Deleted!", "Your imaginary file has been deleted.", "success");
        });
    });
