In this blog post you will see a script that I’ve demonstrated on my YouTube channel to play any YouTube video dynamically by clicking a button or typing a video id easily.
Here is the script:
<!DOCTYPE html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Tutorial</title>
</head>
<body>
<!-- 1. The <iframe> (video player) will replace this <div> tag. -->
<div id="player"></div>
<button onclick="playThisVideo('ox3a3mVyfNM')">Video 1</button>
<button onclick="playThisVideo('Xen01afIaQI')">Video 2</button>
<button onclick="playThisVideo('n_kvlUIUH9Q')">Video 3</button>
<input id="somevidid">
<button onclick="playanothervideo()">Play this video</button>
<script>
// 2. This code loads the IFrame Player API code 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);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
function onYouTubeIframeAPIReady() {
console.log("YouTube is ready!");
}
// 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();
}
var player;
function playThisVideo(vidid){
if(player){
player.destroy();
}
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: vidid,
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function playanothervideo(){
var vidid = document.getElementById("somevidid").value;
//alert("Video: " + vidid);
playThisVideo(vidid);
}
</script>
</body>
</html>
The script is originally found here but I modified it and added a useful function to it so we can play more than one video dynamically.
