Possible to add an onclick event to a YouTube iframe? - javascript

I've got a site with an HTML5 audio player and embedded YouTube music videos. I'd like to make it so that when the user clicks on a YouTube video to play it the music will stop. Wrapping the iframe in
<div id='vidWrapper' onclick='pauseAudio()'>YT stuff</div>
works for the sliver of pixels outside of the iframe, but not when you click on the actual video. Anyone have any ideas?

You should use the YouTube IFrame API. Add an event listener for onStateChange to get notified when the player's state changes. See the sample code below.
<!DOCTYPE html>
<html>
<head>
<script src="https://www.youtube.com/iframe_api"></script>
</head>
<body>
<div id='vidWrapper'>
<!-- The <iframe> (and video player) will replace this <div> tag. -->
<div id="ytplayer"></div>
</div>
<script>
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('ytplayer', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
events: {
'onStateChange': function(event) {
if (event.data == YT.PlayerState.PLAYING) {
pauseAudio();
}
}
}
});
}
function pauseAudio() {
...
}
</script>
</body>
</html>

//More Refined Way to answer this question would be --
//HTML code----
<!DOCTYPE html>
<html>
<body>
<div id='vidWrapper'>
//your iframe tag goes here.
<iframe id="video-id-first" src="https://www.youtube.com/embed/nNlEiuqiKAk?enablejsapi=1&origin=http%3A%2F%2F3.7.232.244" gesture="media" allow="encrypted-media" allowfullscreen="" data-gtm-yt-inspected-53610233_3="true" width="560" height="400" frameborder="0"></iframe>
</div>
</body>
</html>
//JS code ----
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 player;
var width = document.getElementById("video-id-first").getAttribute("width");
var height = document.getElementById("video-id-first").getAttribute("height");
var src = document.getElementById("video-id-first").getAttribute("src");
//splitting to get the videoId from src.
var partsArr = src.split("/");
var videoSource = partsArr[partsArr.length -1 ].split("?");
var videoId = videoSource[videoSource.length -2 ];
function onYouTubeIframeAPIReady() {
player = new YT.Player('vidWrapper', {
height:height,
width: width,
videoId: videoId,
events: {
'onStateChange': function(event) {
if (event.data == YT.PlayerState.PLAYING) {
startVideo();
}
if (event.data == YT.PlayerState.PAUSED) {
stopVideo();
}
}
}
});
}
function startVideo() {
//write your functionality here.
alert('Video Started');
}
function stopVideo() {
//write your functionality here.
alert('Video Paused');

youtube autoplay is not working

I am using youtube embed to display a video. I need to autoplay when site is opened
<iframe class="slider-image-mockup align-center" width="100%" height="750" src="https://www.youtube-nocookie.com/embed/Y-p828Jy8C8?rel=0&controls=0&autoplay=1&loop=1&playlist=Y-p828Jy8C8&showinfo=0" frameborder="0" allow="autoplay; loop; encrypted-media" allowfullscreen></iframe>
I am using this code before it was working fine but for past few days. Autoplay is not working...
It may sound crazy but I didn't change anything in my code.
its showing like below after clicking of play button only video is playing
<!DOCTYPE html>
<html>

var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>

now I have changed the url
from : https://www.youtube-nocookie.com/embed/Y-p828Jy8C8?rel=0&controls=0&autoplay=1&loop=1&playlist=Y-p828Jy8C8&showinfo=0

now its working... Thank you..

How do I convert this script to a js file?

I have this script that I need as a .js file, so I can use it multiple times without having multiple copies of the script everywhere, like calliing the script YTiFramePlayer.js. But, maybe I want to change promoVideo, or videoId. How would I do that?
//YouTube iframe player
//Load the iframe Player API
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 player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('promoVideo', {
height: '390',
width: '640',
videoId: '00000',
events: {
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.STOPPED) {
stopVideo();
}
}
function startVideo() {
$("#video").css("height", "calc(100vh - 48px)");
player.playVideo();
}
function stopVideo() {
player.stopVideo();
$("#video").css("height", "0px");
}
You can save this as a .js file as mentioned previously, but wrap the functionality in a global variable that you can access elsewhere. Example:
script.js:
//YouTube iframe player
//Load the iframe Player API
var ytPlayer = (function() {
var tag = document.createElement('script');
var videoId;
var promoVideo = 'promoVideo';
var player;
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
return {
init(id, promoVideo) {
videoId = id;
promoVideo = promoVideo;
onYouTubeIframeAPIReady();
}
}
function onYouTubeIframeAPIReady() {
console.log('Setting up:', videoId, promoVideo)
player = new YT.Player(promoVideo, {
height: '390',
width: '640',
videoId: videoId,
events: {
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.STOPPED) {
stopVideo();
}
}
function startVideo() {
$("#video").css("height", "calc(100vh - 48px)");
player.playVideo();
}
function stopVideo() {
player.stopVideo();
$("#video").css("height", "0px");
}
})();

YouTube IFrame API with existing IFrame failing to run callbacks

Somewhat related to:
YouTube IFrame API doesn't always load?
But different in that I AM loading the YouTube script per instructions. Note, in my source, the iframe is ABOVE the script block in the load order. I based this off of these instructions (below). The example works fine if I'm on that page, but doesn't seem to work for me when I put the code on mine. I'm sure I'm missing something really simple but I'm to be missing it. Thanks!

Best way to load a Youtube Video by his API, is following this sintaxis:
<div id="video-youtube"></div>
<script id="youtube-tracking-script">
var youtubeVideoId = 'u3A7bmEOtaU'; // replace with your own video id
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementById("youtube-tracking-script");
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var video;
function onYouTubeIframeAPIReady() {
video = new YT.Player('video-youtube', {
height: '352',
width: '100%',
videoId: youtubeVideoId,
playerVars: {rel: 0, showinfo: 0},
events: {
'onStateChange': videoPlay
}
});
}
function videoPlay(event) {
if (event.data == YT.PlayerState.PLAYING) {
console.log("YouTube Video is PLAYING!!");
}
if (event.data == YT.PlayerState.PAUSED) {
console.log("YouTube Video is PAUSED!!");
}
if (event.data == YT.PlayerState.ENDED) {
console.log("YouTube Video is ENDING!!");
}
}
</script>

You should replace your <iframe> </iframe> to <div id= "js_youTubeFrame"> </div>, in my case it works.
I think that Youtube Iframe Api needs that div to convert it on iframe after.

jQuery Mobile Popup with custom YouTube Controls

I would like to create a jQuery Mobile Popup (or any type of javascript modal) which embeds a YouTube Video and allows for custom controls.
Here is a JSFiddle demo with a basic "Play" button which hopefully helps demonstrate my problem.
Basically, I have the iframe code in HTML:
<iframe id="iframe-video" width="400" height="300" src="http://www.youtube.com/embed/a0gact_tf_0" frameborder="0" allowfullscreen></iframe>
And then, when the video is loaded I do this:
$(document).on("pagecreate", function() {
// bind click events
$(document).on('click', '#play', function() {
playVideo();
return false;
});
$(".ui-popup iframe")
.attr("width", 0)
.attr("height", "auto");
$("#popupVideo").on({
popupbeforeposition: function() {
initYoutubePlayer();
// call our custom function scale() to get the width and height
var size = scale(497, 298, 15, 1),
w = size.width,
h = size.height;
$("#popupVideo iframe")
.attr("width", w)
.attr("height", h);
},
popupafterclose: function() {
$("#popupVideo").html("<span></span>");
$("#popupVideo iframe")
.attr("width", 0)
.attr("height", 0);
},
});
});
function initYoutubePlayer() {
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 player;
function onYouTubeIframeAPIReady() {
alert('onYouTubeIframeAPIReady');
player = new YT.Player('iframe-video', {
events: {
'onReady': onPlayerReady,
}
});
};
function onPlayerReady(event) {
alert('ready');
};
alert('initialized');
}
function playVideo() {
alert('playVideo...');
//player.playVideo();
}
Loading the video works fine but I can't get the YouTube iFrame API working where I can instantiate the YT.Player. In other words, 'onYouTubeIframeAPIReady' does not fire.
I have tried all sorts of permutations of this JSFiddle code but feel like I may be missing something obvious.
Is it possible to have custom YouTube controls within a jQuery Mobile Popup or javascript modal?

Lazy Load youtube video from iframe API

I want to lazy load the youtube video with iframe API. ie. load only the poster image in the beginning and when user clicks on it then only load the actual image and its content.
Most of this is taken from the getting started section on the youtube page.
<!-- 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 = "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.
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>
This example loads the video when it is ready.
So we change it up a bit to add in a placeholder image and on click hide the image and play the video.
Wrap the tag (step 2) in function
function loadYT() {
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
}
Add an image Check this question for more details on sizes.
<div id="placeholder">
<img src="http://img.youtube.com/vi/M7lc1UVf-VE/sddefault.jpg" />
</div>
Then on click hide the placeholder image and load the player
document.getElementById("placeholder").addEventListener("click", function(){
this.style.display = 'none';
loadYT()
});
Final result can be seen below.
<div id="placeholder">
<img src="http://img.youtube.com/vi/M7lc1UVf-VE/sddefault.jpg" />
</div>
</div>
<div id="player"></div>
<script>
document.getElementById("placeholder").addEventListener("click", function(){
this.style.display = 'none';
loadYT()
});
// 2. This code loads the IFrame Player API code asynchronously.
function loadYT() {
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.
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>
Why load the videos on click, and not just when the user sees them? Use jQuery.Lazy and you have nothing more to do. :)
Add the Plugin to your Page: (you will need jQuery or Zepto as well)
<script type="text/javascript" src="//cdn.jsdelivr.net/jquery.lazy/1.7.1/jquery.lazy.min.js"></script>
<script type="text/javascript" src="//cdn.jsdelivr.net/jquery.lazy/1.7.1/plugins/jquery.lazy.youtube.min.js"></script>
Prepare your iFrames: (note the data-loader and data-src attributes)
<iframe data-loader="youtube" data-src="1AYGnw6MwFM" width="560" height="315"></iframe>
And start using Lazy:
$(function() {
$("iframe[data-src]").Lazy();
});
That's it! The iFrames will be loaded whenever the user reaches them by scrolling. More inormations here.
<iframe loading="lazy"
This HTML feature allows lazy loading YouTube iframe embeds only when the user scrolls over them, without any extra JavaScript (the YouTube video is of course automatically loaded via JavaScript in the iframe however).
Here is a working jsfiddle: https://jsfiddle.net/cirosantilli/3p0tk5nc/1/ that I have tested on Chromium 81. You can see on the developer tools "network" tab that the frames only load when you scroll over them.
It does not work on Stack Overflow snippets for some reason however because YouTube videos appear to not work on Stack Overflow in general, not because of loading="lazy" in particular.

DEMO
I just lazy load the thumbnail and only load the real video if the visitor is hovering the thumbnail. For Privacy reasons you can also make him click a confirmation before loading the video from youtube.
<?php $youtubevideo="Video ID1"; $youtubezaehler=$youtubezaehler+1;?>
<br>
<div align="center" class="video-container" onmouseover="video<?php echo($youtubezaehler);?>()">
<div style="position:relative;">
<img loading="lazy" id="vorschaubild<?php echo($youtubezaehler);?>" class="" src="https://img.youtube.com/vi/<?php echo($youtubevideo);?>/<?php echo $youtube_aufloesung; ?>" width="100%" alt="Lade...">
<div id="play<?php echo($youtubezaehler);?>" style="position:absolute; top:30%; left:46%; width:10%;"><img src="play.gif" alt="Play" style="width:100%;"></div>
</div>
<script type="text/javascript">
<!--
//JavaScript zum DSGVO konformem und Ladezeitoptimierten Einbinden der Youtube Videos erst bei Nutzung
function video<?php echo($youtubezaehler);?>() {
if(document.getElementById("vorschaubild<?php echo($youtubezaehler);?>").style.visibility=="hidden") return false; //Damit das Video nicht beim abspielen versehntlich neu geladen wird
document.getElementById("vorschaubild<?php echo($youtubezaehler);?>").height = "1px";
document.getElementById("vorschaubild<?php echo($youtubezaehler);?>").style.visibility="hidden";
document.getElementById("play<?php echo($youtubezaehler);?>").style.visibility="hidden";
document.getElementById("video<?php echo($youtubezaehler);?>").src = "https://www.youtube-nocookie.com/embed/<?php echo($youtubevideo);?>?rel=0";
}
// -->
</script>
<iframe title="Video" id="video<?php echo($youtubezaehler);?>" src="" frameborder="0" allowfullscreen></iframe>
</div>
Finally it worked, below code is in angularJS.
HTML
<div data-ng-repeat="video in videoIds track by $index">
<div id="uniQueId" ng-click="playVideo(video, 'player' + $index)">
<div class="video-play-button"></div>
</div>
</div>
JS
$scope.playVideo = function(videoId, id) {
$scope.players[id] = new YT.Player(id, {
videoId: videoId,
width: '400',
height: '300',
playerVars: { 'autoplay': 1 },
events: {
'onStateChange': $scope.onPlayerStateChange
}
});
};
