I have a simple index.html file like this:
<!DOCTYPE html>
<html lang="en">
  <head>
    <title>Test</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
    <script type="text/javascript">
      $(function() {
        setInterval(function(){
          if (typeof Cocoa !== 'undefined') {
            Cocoa.log('JQuery loaded...');
          }
        }, 3000);
      });
    </script>
  </head>
  <body>
    <h1>Testing script in objective c enviroment.</h1>
    <div id="container" class="col">
      <p>Paragraph 1</p>
      <p>content goes here</p>
    </div>
  </body>
</html>

Why does nothing inside $(function() {}); get called? If I place the interval log function outside the JQuery onReady function, it does start to call the correct method after a few seconds.
Is there some cross-site policy issue going on that's preventing scripts from being loaded? If so, how can I disable it? Why isn't jQuery loading?
