I'm Trying to Play a Youtube Video with Javascript and the Tag. So Far I'm Getting This Error: "Document. getElementById(. ..). playVideo Is Not a Function"...
I'm trying to play a youtube video with javascript and the <iframe> tag. So far I'm getting this error: "document.getElementById(...).playVideo is not a function". Here's my code:
Javascript:
document.getElementById("video").playVideo();
HTML:
<iframe id="video" src="url"> </iframe>

Are you trying to autoplay the video ? In that case you will need to add ?autoplay=1 at the end of the youtube URL and add an allow attribute to your iframe tag like shown below
<iframe src="" allow='autoplay'></iframe>
If you want to use javascript to control the videoplayer, I would recommend using the Youtube Player API. Sample code is as below (taken from youtube's documentation) -
<!DOCTYPE html>
<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "";
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() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
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, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>
</html>
