javascript - 关闭模式时停止 YouTube 视频

Question

这是我的标记。我不确定关闭模式时需要做什么才能让视频停止播放。它在 Chrome 中停止正常播放，但在 Firefox 中视频继续在后台播放。

    <!-- Modal -->
    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
          <div class="modal-body">

            <iframe id="iframeYoutube" width="854" height="480"  src="https://www.youtube.com/embed/TFpFJeWOvZg?rel=0" frameborder="0" allowfullscreen></iframe> 

          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
          </div>
        </div>
      </div>
    </div>

<script>
  $(document).ready(function(){
  $("#myModal").on("hidden.bs.modal",function(){
    $("#iframeYoutube").attr("src","#");
  })
})

function changeVideo(vId){
  var iframe=document.getElementById("iframeYoutube");
  iframe.src="https://www.youtube.com/embed/"+vId;

  $("#myModal").modal("show");
}
</script>

请尝试这个方法..

$(document).ready(function(){
    /* Get iframe src attribute value i.e. YouTube video url
    and store it in a variable */
    var url = $("#cartoonVideo").attr('src');
    
    /* Assign empty url value to the iframe src attribute when
    modal hide, which stop the video playing */
    $("#myModal").on('hide.bs.modal', function(){
        $("#cartoonVideo").attr('src', '');
    });
    
    /* Assign the initially stored url back to the iframe src
    attribute when modal is displayed again */
    $("#myModal").on('show.bs.modal', function(){
        $("#cartoonVideo").attr('src', url);
    });
});

 .bs-example{
    	margin: 20px;
    }
    .modal-content iframe{
        margin: 0 auto;
        display: block;
    }
