Bootstrap 3 and Youtube in Modal

Question

I found this problem (or the problem I found and described at https://github.com/twbs/bootstrap/issues/10489) related to CSS3 transformation (translation) on the .modal.fade .modal-dialog class.

In bootstrap.css you will find the lines shown below:

.modal.fade .modal-dialog {
  -webkit-transform: translate(0, -25%);
      -ms-transform: translate(0, -25%);
          transform: translate(0, -25%);
  -webkit-transition: -webkit-transform 0.3s ease-out;
     -moz-transition: -moz-transform 0.3s ease-out;
       -o-transition: -o-transform 0.3s ease-out;
          transition: transform 0.3s ease-out;
}

.modal.in .modal-dialog {
  -webkit-transform: translate(0, 0);
      -ms-transform: translate(0, 0);
          transform: translate(0, 0);
}

Replacing these lines with the following will show the movie correctly (in my case):

.modal.fade .modal-dialog {
  -webkit-transition: -webkit-transform 0.3s ease-out;
     -moz-transition: -moz-transform 0.3s ease-out;
       -o-transition: -o-transform 0.3s ease-out;
          transition: transform 0.3s ease-out;
}

.modal.in .modal-dialog {

}

I put together this html/jQuery dynamic YouTube video modal script that auto plays the YouTube video when the trigger (link) is clicked, the trigger also contains the link to play. The script will find the native bootstrap modal call and open the shared modal template with the data from the trigger. See Below and let me know what you think. I would love to hear thoughts...

HTML MODAL TRIGGER:

 <a href="#" class="btn btn-default" data-toggle="modal" data-target="#videoModal" data-theVideo="http://www.youtube.com/embed/loFtozxZG0s" >VIDEO</a>

HTML MODAL VIDEO TEMPLATE:

<div class="modal fade" id="videoModal" tabindex="-1" role="dialog" aria-labelledby="videoModal" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-body">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <div>
          <iframe width="100%" height="350" src=""></iframe>
        </div>
      </div>
    </div>
  </div>
</div>

THE JQUERY FUNCTION:

//FUNCTION TO GET AND AUTO PLAY YOUTUBE VIDEO FROM DATATAG
function autoPlayYouTubeModal(){
  var trigger = $("body").find('[data-toggle="modal"]');
  trigger.click(function() {
    var theModal = $(this).data( "target" ),
    videoSRC = $(this).attr( "data-theVideo" ), 
    videoSRCauto = videoSRC+"?autoplay=1" ;
    $(theModal+' iframe').attr('src', videoSRCauto);
    $(theModal+' button.close').click(function () {
        $(theModal+' iframe').attr('src', videoSRC);
    });   
  });
}

THE FUNCTION CALL:

$(document).ready(function(){
  autoPlayYouTubeModal();
});

I have one tip for you!

I would use:

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

instead of:

$('#myModal button').click(function () {
    $('#myModal iframe').removeAttr('src');
});

Because you can also close the modal without the button, so there for with this code it will remove the video every time the modal will hide.

Found this in another thread, and it works great on desktop and mobile - which is something that didn't seem true with some of the other solutions. Add this script to the end of your page:

<!--Script stops video from playing when modal is closed-->
<script>
    $("#myModal").on('hidden.bs.modal', function (e) {
        $("#myModal iframe").attr("src", $("#myModal iframe").attr("src"));
    });
</script>
