When I hide a YouTube video, it stops playing. However, this is not the case for Vimeo videos. Is there another way to stop a Vimeo video?
First, add an ID to your iFrame. Then add this to your javascript close window click function:
var $frame = $('iframe#yourIframeId');
// saves the current iframe source
var vidsrc = $frame.attr('src');
// sets the source to nothing, stopping the video
$frame.attr('src','');
// sets it back to the correct link so that it reloads immediately on the next window open
$frame.attr('src', vidsrc);
