How to pause a YouTube player when hiding the iframe?

The easiest way to implement this behaviour is by calling the pauseVideo and playVideo methods, when necessary. Inspired by the result of my previous answer, I have written a pluginless function to achieve the desired behaviour.

The only adjustments:

  • I have added a function, toggleVideo
  • I have added ?enablejsapi=1 to YouTube’s URL, to enable the feature

Demo: http://jsfiddle.net/ZcMkt/
Code:

<script>
function toggleVideo(state) {
    // if state == 'hide', hide. Else: show video
    var div = document.getElementById("popupVid");
    var iframe = div.getElementsByTagName("iframe")[0].contentWindow;
    div.style.display = state == 'hide' ? 'none' : '';
    func = state == 'hide' ? 'pauseVideo' : 'playVideo';
    iframe.postMessage('{"event":"command","func":"' + func + '","args":""}', '*');
}
</script>

<!-- popup and contents -->
<div id="popupVid" style="position:absolute;left:0px;top:87px;width:500px;background-color:#D05F27;height:auto;display:none;z-index:200;">
   <iframe width="500" height="315" src="http://www.youtube.com/embed/T39hYJAwR40?enablejsapi=1" frameborder="0" allowfullscreen></iframe>
   <br /><br />
