在表单提交时加载模态

I am trying to load a "thank you" modal when submitting my form.

I have 3 files, magic.js (which does the JQ magic), index.html and process.php.

Below is the code for each of the 3 files, and I can't for the life of me get it to work.

When the form is submitted it just loads the process.php page and displays success = true

if I remove the action="process.php" from the form tag I just get a Method Not Allowed error.

index.html:

<html>
<head>
    <title>Look I'm AJAXing!</title>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> <!-- load jquery via CDN -->
    <script src="magic.js"></script> <!-- load our javascript file -->
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css"> <!-- load bootstrap via CDN -->
</head>
<body>
<div class="col-sm-6 col-sm-offset-3">

    You never actually create the modal on forum submit.

    You only hide on success.

    $("tyModal").modal('hide');
    

    You also have not created the modal on the page either, as myModal is the only one that exists. Not tyModal.

    Another issue is that #thanks does not exists, so you are technically populating the data with nothing.

    success: function(data) {
        $("#thanks").html(data);
        jQuery("#myModal").modal('show');
    }
    

    This is the code that I use.

    HTML

    <!-- data-backdrop="static" -->
    <div class="modal fade" id="myAjaxModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static" data-keyboard="false">
        <div class="modal-dialog">
            <div class="modal-content" id="myAjaxModalContent">
            </div><!-- end modal-content -->
        </div>
        <!-- end modal-dialog -->
    </div>
    <!-- end modal -->
    

    JS

    function showModal() {
       $( "#myAjaxModal .modal-content" ).html('test');
        $('#myAjaxModal').modal('show');
    }
