Форма, не отправляющая при попытке использования jQuery's submitHandler

Я конвертирую форму контакта в AJAX, чтобы я мог выполнять функцию успеха. В настоящий момент код останавливается в секции submitHandler, говоря, что он не определен. Как мой submitHandler не определен?

submitHandler(function(form) {

• Переключить загрузочный модальный с помощью php-триггера
• Загрузочная разбивка по страницам встроенная реализация
• Webhoster вставляет javascript, который вызывает мой код, как его удалить?
• Предотвратите ввод пустой формы из отправки пустого значения в базу данных после ее удаления с помощью jquery и ajax
• Динамически отправлять сообщение WordPress

Правильно ли я делаю это? Я хочу использовать мой текущий php, потому что я построил его для проверки подлинности на основе проверки jQuery.

Кто-нибудь видит, что не так с submitHandler, и все, что может помешать этому отправлять?

HTML

 <div class="contact-container"> <form id="contactform" method="post" action="" novalidate> <?php if($sent === true) { echo "<h2 class='success'>Thanks, your message has been sent successfully</h2>"; } elseif($hasError === true) { echo '<ul class="errorlist">'; foreach($errorArray as $key => $val) { echo "<li>" . ucfirst($key) . " field error - $val</li>"; } echo '</ul>'; } ?> <div> <input type="text" class="contact_input" name="name" id="name" value="<?php echo (isset($name) ? $name : ""); ?>" placeholder="Name"> </div> <div> <input type="email" class="contact_input" name="email" id="email" value="<?php echo (isset($email) ? $email : ""); ?>" placeholder="Email"> </div> <div> <textarea name="message" class="contact_input" id="message" placeholder="Message"><?php echo (isset($message) ? $message : ""); ?></textarea> </div> <input type="submit" id="submit_contact" class="clear" name="submitform" value="Send"> </form> </div> <div class="contact-email-success"> <div class="contact-email-success-container"> <div id="contact-email-success-title">THANK YOU FOR CONTACTING OUR AGENCY!</div> <div id="contact-email-success-description">Your submission has been received and one of our team members will contact you shortly.</div> </div> </div>
