Introducing JavaScript Player API for iframe embeds
Thursday, January 20, 2011
Update (July 2012):
The
onYouTubePlayerAPIReady
callback has been superseded by
onYouTubeIframeAPIReady
and the URL for loading the IFrame Player API code has changed to
http(s)://www.youtube.com/iframe_api.
The API is now fully supported.
If you have been enjoying our
<iframe>
embed
announced
back in July we have some good news for you. Starting today, the
<iframe>
embed code is the default way to
share videos
on YouTube.com. We are also introducing
an initial beta version of
the
<iframe>
embed JavaScript Player API, making it a viable alternative for developers who previously used the API exposed by the ActionScript players. Let’s look at an example of the API usage:
<!DOCTYPE HTML>
<html>
<body>
<div id="player"></div>
<script>
//Load player api asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var done = false;
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'JW5meKfy3fY',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(evt) {
evt.target.playVideo();
}
function onPlayerStateChange(evt) {
if (evt.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>
</html>
This example will play a video for several seconds and then stop playback. An instance of
YT.Player
is used to control the player, defined by script loaded from
http(s)://www.youtube.com/iframe_api
. For more information about the API usage, as always, please consult our Player API
documentation
and let us know what you think on our
Developer Forum
.
Cheers,
