Using Youtube Javascript API for multiple videos - api

Question

I am trying to find a way to use Youtube API to have multiple videos with each in its own hidden div where each one is called up by their corresponding thumbnails. I am having a hard time finding out how to get the close button of the once hidden div to also stop that particular video. I can only get one to do it right and the other will not. My code below:
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player1 = new YT.Player('popupVid1', {
height: '408',
width: '725',
videoId: '6Bp1c3-AeXQ',
playerVars: {
wmode: "opaque"
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
player2 = new YT.Player('popupVid2', {
height: '408',
width: '725',
videoId: '6Bp1c3-AeXQ',
playerVars: {
wmode: "opaque"
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo,loop);
done = true;
}
}
function stopVideo1() {
player1.stopVideo();
}
function stopVideo2() {
player2.stopVideo();
}
