How to clear form after ajax submit? - php

Question

I have a small contact form. Sending messages is working but the form stays with text after submitting. I searched and tried some code to clear it with no success.
// JavaScript Document
$('#contact-form').submit(function (e) {
"use strict";
e.preventDefault();
$.ajax({
type: "POST",
url: "contactform.php",
data: $(this).serialize(), //get form values
sucess: function (data) {
document.getElementById("contact-form").reset();
}
}).done(function (data) {
console.log(data); // will contain success or invalid
});
});
And some php
<?php
$firstname = $_POST["firstname"];
$lastname = $_POST["lastname"];
$email = $_POST["email"];
$phone = $_POST["phone"];
$message = $_POST["message"];
$EmailTo = "marcin#rmonline.com";
$Subject = "New Message Received";
// prepare email body text
$email_content .= "Firstname: $firstname\n";
$email_content .= "Lastname: $lastname\n";
$email_content .= "Email: $email\n";
$email_content .= "Phone: $phone\n";
$email_content .= "Message: $message";
// send email
$success = mail($EmailTo, $Subject, $email_content, "From:".$email);
// redirect to success page
if ($success){
echo "success";
} else {
echo "invalid";
}
?>
And html
<form id="contact-form" method="post" action="contactform.php" role="form">
<div class="messages"></div>
<div class="form-group">
<input id="form_name" type="text" name="firstname" class="form-control" placeholder="Please enter your firstname *" required="required" data-error="Firstname is required.">
<div class="help-block with-errors"></div>
</div>
<div class="form-group">
<input id="form_lastname" type="text" name="lastname" class="form-control" placeholder="Please enter your lastname *" required="required" data-error="Lastname is required.">
<div class="help-block with-errors"></div>
</div>
<div class="form-group">
<input id="form_email" type="email" name="email" class="form-control" placeholder="Please enter your email *" required="required" data-error="Valid email is required.">
<div class="help-block with-errors"></div>
</div>
<div class="form-group">
<input id="form_phone" type="tel" name="phone" class="form-control" placeholder="Please enter your phone">
<div class="help-block with-errors"></div>
</div>
<div class="form-group">
<textarea id="form_message" name="message" class="form-control" placeholder="Message for us *" rows="4" required data-error="Please,leave us a message."></textarea>
<div class="help-block with-errors"></div>
</div>
<button type="submit" class="btn" value="Send message">Send Message</button>
<p class="text-muted"><strong>*</strong> These fields are required.</p>
</form>
I've got the feeling that I'm missing something, but don't know what yet.

Try removing the preventDefault. The form will empty once the page reloads. That or you will have to manually set the value of the form inputs to empty.
Is there a particular reason you are submitting the form using ajax and not allowing the form to post directly to the php file?
