While I was cobbling this site together I never gave a lot of thought to what would happen if you had several YouTube videos on a page and the possibility that none or all of them could be playing at any given time! Ideally, there should be only one. That being said, I set out to find a solution for the problem.

With a little bit of google--fu it turns out the answer was fairly simple. The javascript above iterates through all the iframes on the page and filters the src attribute containing https://www.youtube.com.Next the script iterates through the resulting I frames and binds to the onStateChange so that when one video is played it pauses any other video that is currently playing.
I had found this link and incorporated it. I thought it would be a good idea to write it down before it got lost to my memory and the interwebs. You can check it out in the forums.
