Twitter Bootstrap Modal stop Youtube video

I'm very new to javascript and trying to use Twitter bootstrap to get a good looking website up and running quickly. I know this has something to do with jquery, but I'm not sure how to stop my video when I push the close button or the close icon.

Can someone explain how I can get my video to stop playing because even when I close the window, I can still hear it in the background.

<!-- Button to trigger modal -->
    <a href="#myModal" role="button" class="btn" data-toggle="modal"><img src="img/play.png"></a>

<!-- Modal -->
  <div id="myModal" class="modal hide fade" tabindex="-1" role=labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria>×</button>
      <h3 id="myModalLabel">I am the header</h3>
    </div>
    <div class="modal-body">
      <p><iframe width="100%" height="315" src="http:com/embed/662KGcqjT5Q" frameborder="0" allowfullscreen></iframe></p>
    </div>
    <div class="modal-footer">
      <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
    </div>
  </div>

I know I'm 2+ years late, but since then, a couple of things have changed, with B3 the new way to perform this out of the box is this:

$("#myModal").on('hidden.bs.modal', function (e) {
    $("#myModal iframe").attr("src", $("#myModal iframe").attr("src"));
});

Have fun with Bootstrap!

There is a nice proper way of doing this - see the comments in the approved answer to this post.

Couldn't get that working first time round myself though, and was in a rush, so I did a rather horrible hacky bit of code which does the trick.

This snippet 'refreshes' the src of the embed iframe, causing it to reload:

jQuery(".modal-backdrop, #myModal .close, #myModal .btn").live("click", function() {
        jQuery("#myModal iframe").attr("src", jQuery("#myModal iframe").attr("src"));
});

If someone still has the problem, try this, it worked for me:

$(document).ready(function(){
    $('.modal').each(function(){
            var src = $(this).find('iframe').attr('src');

        $(this).on('click', function(){

            $(this).find('iframe').attr('src', '');
            $(this).find('iframe').attr('src', src);

        });
    });
});
