Few topics on this but no answers for me.

Embedding youtube video in a overlay div:

```
   <div id="blanket" style="display:none;">
     </div>
        <div id="popUpDiv" style="display:none;">
        <a href="#" onclick="popup('popUpDiv')">Close</a>     
        <iframe width="480" height="390" src="https://www.youtube.com/embed/G5AuItKv?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>                                       
        </div>

```

On firefox when I close the window the video stops, but not in chrome or internet explorer. 

Is there some simple javascript I can use to stop it when the user clicks Close?

TIA
