Try this:
试试这个：
var $$ = function(tagname) { return document.getElementsByTagName(tagname); }
function onYouTubeIframeAPIReady() {
var videos = $$('iframe'), // the iframes elements
players = [], // an array where we stock each videos youtube instances class
playingID = null; // stock the current playing video
for (var i = 0; i < videos.length; i++) // for each iframes
{
var currentIframeID = videos[i].id; // we get the iframe ID
players[currentIframeID] = new YT.Player(currentIframeID); // we stock in the array the instance
// note, the key of each array element will be the iframe ID
videos[i].onmouseover = function(e) { // assigning a callback for this event
var currentHoveredElement = e.target;
if (playingID) // if a video is currently played
{
players[playingID].pauseVideo();
}
players[currentHoveredElement.id].playVideo();
playingID = currentHoveredElement.id;
};
}
}
onYouTubeIframeAPIReady();
