I want to validate an user input with ajax. It is the first time I use Ajax and I got stuck. If the input is correct I still get an error message and I don't know why.
I get as an error 'Subtax error in the jquery file'. What do I do wrong? Thank you in advance.
HTML:
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<div class="form-group">
<label for="inputName">Your name</label>
<input type="text" name="inputName" class="form-control" id="inputName" placeholder="Name">
</div>
<div class="form-group">
<label for="inputEmail">Your e-mail</label>
<input type="text" name="inputEmail" class="form-control" id="inputEmail" placeholder="E-mail">
</div>
<div class="form-group">
<label for="inputMess">Your message for us</label>
<textarea name="inputMess" class="form-control" id="inputMess"></textarea>
</div>
<button type="submit" name="send" class="btn btn-default">Send</button>
</form>
<div id='mess'></div>
PHP:
<?php
sleep(1);
$mail_reg = '/^(?i)(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9] {1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/';
$return = array();
$mesaj = '';
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
if (empty($_POST['inputName']) || is_numeric($_POST['inputName'])) {
$mesaj = "Please enter your name!";
$return['error'] = true;
$return['msg'] = 'oops'.$mesaj;
echo json_encode($return);
exit();
} elseif (empty($_POST['inputEmail']) || !preg_match($mail_reg, $_POST['inputEmail'])) {
$mesaj = "Please enter your e-mail!";
$return['error'] = true;
$return['msg'] = 'oops'.$mesaj;
echo json_encode($return);
exit();
} elseif (empty($_POST['inputMess'])) {
$mesaj = "Please tell us something";
$return['error'] = true;
$return['msg'] = 'oops'.$mesaj;
echo json_encode($return);
exit();
} else {
$return['error'] = false;
$return['msg'] = 'Thank you for getting in touch. We will contact you!';
echo json_encode($return);
exit();
}
}
?>
JavaScript:

$('form').submit(function(event) {
event.preventDefault();
if ($('#inputName').val() == '' || $('#inputName').val().length < 2 || !isNaN($('#inputName').val())) {
alert('Please enter your name');
} else if (!email_reg.test($('#inputEmail').val())) {
alert('Please enter a valid e-mail adress');
} else if ($('#inputMess').val() == '' || !isNaN($('#inputMess').val())) {
alert('Please tell us something');
} else {
var formData = $('form').serialize();
submitForm(formData);
}
})
function submitForm(formData) {
$.ajax({
type: 'POST',
url: $('form').action,
data: formData,
dataType: 'json',
cache: false,

success: function(data) {
