How to Add if statement to Ajax of Bootstrap Notify

Experts!

Is there a way to check type of notify (success or danger) and add a code as in the following code?

I added an automatic button click in the Ajax code so that the DataTable can be refreshed after success. I don't want to perform the button click if there's an error so the DataTable doesn't refresh. Because if it does, the user input will be wiped out.

$('#add_assessment').click(function() {

                $.ajax({
                url     : 'assessment_add_controller.php',
                method  : 'post',
                data    : $('#assessmentForm').serialize(),
                dataType : 'json',
                }).done(function(response) {
                    $('button[name=loadStudents]').click();
                    var type = response.status ? 'success' : 'danger';
                  $.notify({
                    // options
                    message: response.message
                    },{
                    // settings
                      type: type + ' my-notify',
                      placement: {
                        align: 'center' 
                    },
                    animate: {
                        enter: 'animated fadeInDown',
                        exit: 'animated fadeOutUp'
                    }
                                           
                  });

                });

            });

Or can I just perform array_filter() in the Ajax before it gets to Insert/Update in the script?

I'm doing it this way:

$missingCA1 = count( array_filter($_POST['cass1'], function($i) { return $i == 0 || $i > 10; }) );
$missingCA2 = count( array_filter($_POST['cass2'], function($i) { return $i == 0 || $i > 10; }) );
$missingCA3 = count( array_filter($_POST['cass3'], function($i) { return $i == 0 || $i > 10; }) );
$missingExam = count( array_filter($_POST['exam'], function($i) { return $i == 0 || $i > 70; }) );

    if ( $missingCA1 ){
        $response->message = "CA1 scores must be greater than <strong>0</strong> and NOT more than <strong>10</strong>";
        die( json_encode($response) );
    }
    if ( $missingCA2 ){
        $response->message = "CA2 scores must be greater than <strong>0</strong> and NOT more than <strong>10</strong>";
        die( json_encode($response) );
    }
    if ( $missingCA3 ){
        $response->message = "CA3 scores must be greater than <strong>0</strong> and NOT more than <strong>10</strong>";
        die( json_encode($response) );
    }
    if ( $missingExam ){
        $response->message = "Exam scores must be greater than <strong>0</strong> and NOT more than <strong>70</strong>";
        die( json_encode($response) );
    }
