Jquery Animation error " ReferenceError: $ is not defined"

I am getting the following error:

ReferenceError: $ is not defined

<!doctype html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <link rel="stylesheet" href="//code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
    <style>
        #navBox {
            width: 150px;
            height: 150px;
            background-color: #004C7E;
        }
    </style>
    <script src="//code.jquery.com/jquery-1.9.1.js"></script>
    <script src="//code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
</head>

<body>
    <div id="navBox"></div>
    <script>
        $(document).click(function () {
            $("#navBox").effect("shake");
        });
    </script>
</body>
</html>

Am I using an outdated jquery version? I was trying to follow this guide: http://api.jqueryui.com/shake-effect/

I expect if you look in your web console, you'll see some 404 errors.

This:

<script src="//code.jquery.com/jquery-1.9.1.js"></script>

...uses a protocol-relative URL. That means if the page was loaded from http://example.com, the protocol will be http:; if from https://example.com, it'll be https:. And critically, if it's file://c/your/stuff, then it's file: and the source doesn't exist.

Using a protocol-relative URL is fine, but if you do, you can't open HTML files directly from your local filesystem and expect them to work. You have to open them through a web server (you can readily install a simple web server on your local system).
