Form submit using AJAX

I have a form I'm trying to submit using the POST method to an email address, The Email sends just fine but all the values are empty. 

      <form id="contact-form" action="mail-script.php" method="POST">
            <label for="form-name">Name:</label>
            <input type="text" name="name" id="form-name" placeholder="Enter Name">

            <label for="form-email">Email:</label>
            <input type="text" name="email" id="form-email" placeholder="Enter Email">

            <label for="form-phone">Phone:</label>
            <input type="text" name="phone" id="form-phone" placeholder=" Enter Phone Number">
            <label for="form-message">Message:</label>
            <textarea name="message" id="form-message"></textarea>
                <input type="submit" class="form-button" id="form-submit" value="Send">
   </form>

$(function(){
    $('#form-submit').click(function(){
       $.ajax({
           type: 'POST',
           url: 'mail-script.php',
           data: $("#contact-form").serialize,
           error: function(){
               alert("error");
           },
           success: function(){
               alert("success");
           }
       }) ;
        return false;
    });
});

<?php
    $MailTo =  'contact@email.com';
    $EmailSubject = 'New Message';
    $body = <<<EOD
    Name: $Name 
    Phone:$Phone
    Email: $Email 
    Message: $Message
    EOD;
    mail($MailTo, $EmailSubject, $body)
?>

Did you grab the values from the post method?

I.E $Name = $_POST["field_name"]

You need to actually call the serialize method in your JavaScript/jQuery, by putting a set of parentheses after the method name:

$(function(){
    $('#form-submit').click(function(){
       $.ajax({
           type: 'POST',
           url: 'mail-script.php',
           data: $("#contact-form").serialize(),
           error: function(){
               alert("error");
           },
           success: function(){
               alert("success");
           }
       }) ;
        return false;
    });
});

And you'd probably be better off handling the form submit event directly rather than the click event on the submit button...

$(function(){
    $('#contact-form').submit(function(event){
       event.preventDefault();
       $.ajax({
           type: 'POST',
           url: 'mail-script.php',
           data: $(this).serialize(),
           error: function(){
               alert("error");
           },
           success: function(){
               alert("success");
           }
       }) ;
    });
});
