[javascript] Stop embedded youtube iframe?

I'm using YouTube iframe to embed videos on my site.

<iframe width="100%" height="443" class="yvideo" id="p1QgNF6J1h0"
              src="http://www.youtube.com/embed/p1QgNF6J1h0?rel=0&controls=0&hd=1&showinfo=0&enablejsapi=1"
              frameborder="0" allowfullscreen>
</iframe>

And i have multiplie videos on the same page.

I want to stop all of them or one of them in a click of a button using javascript or so.

Is it possible?

UPDATE:

I tried what Talvi Watia said and used:

$('#myStopClickButton').click(function(){
  $('.yvideo').each(function(){
    $(this).stopVideo();
  });
});

I'm getting:

Uncaught TypeError: Object [object Object] has no method 'stopVideo' 

For a Twitter Bootstrap modal/popup with a video inside, this worked for me:

$('.modal.stop-video-on-close').on('hidden.bs.modal', function(e) {_x000D_
  $('.video-to-stop', this).each(function() {_x000D_
    this.contentWindow.postMessage('{"event":"command","func":"stopVideo","args":""}', '*');_x000D_
  });_x000D_
});

Based on Marco's answer, notice that I just needed to add the enablejsapi=1 parameter to the video URL (rel=0 is just for not displaying related videos at the end). The JS postMessage function is what does all the heavy lifting, it actually stops the video.

The snippet may not display the video due to request permissions, but in a regular browser this should work as of November of 2018.

Here's a pure javascript solution,

<iframe 
width="100%" 
height="443" 
class="yvideo" 
id="p1QgNF6J1h0"
src="http://www.youtube.com/embed/p1QgNF6J1h0?rel=0&controls=0&hd=1&showinfo=0&enablejsapi=1"
frameborder="0" 
allowfullscreen>
</iframe>
<button id="myStopClickButton">Stop</button>


<script>
document.getElementById("myStopClickButton").addEventListener("click",    function(evt){
var video = document.getElementsByClassName("yvideo");
for (var i=0; i<video.length; i++) {
   video.item(i).contentWindow.postMessage('{"event":"command","func":"stopVideo","args":""}', '*');
}

});

APIs are messy because they keep changing. This pure javascript way worked for me:

 <div id="divScope" class="boom-lightbox" style="display: none;">
    <iframe id="ytplayer" width="720" height="405"   src="https://www.youtube.com/embed/M7lc1UVf-VE" frameborder="0" allowfullscreen>    </iframe>
  </div>  

//if I want i can set scope to a specific region
var myScope = document.getElementById('divScope');      
//otherwise set scope as the entire document
//var myScope = document;

//if there is an iframe inside maybe embedded multimedia video/audio, we should reload so it stops playing
var iframes = myScope.getElementsByTagName("iframe");
if (iframes != null) {
    for (var i = 0; i < iframes.length; i++) {
        iframes[i].src = iframes[i].src; //causes a reload so it stops playing, music, video, etc.
    }
}

How we Pause/stop YouTube iframe to when we use embed videos in modalpopup

 $('#close_one').click(function (e) {
         
         
         let link = document.querySelector('.divclass');// get iframe class 
         let link = document.querySelector('#divid');// get iframe id
         let video_src = link.getAttribute('src');

         $('.youtube-video').children('iframe').attr('src', ''); // set iframe parent div value null 
         $('.youtube-video').children('iframe').attr('src', video_src);// set iframe src again it works perfect

     });

Easiest ways is

var frame = document.getElementById("iframeid");
frame.contentWindow.postMessage('{"event":"command","func":"pauseVideo","args":""}', '*');

Unfortunately these API's evolve very fast. As of May 2015, the proposed solutions don't work anymore, as the player object has no stopVideo method.

A reliable solution is to be found in this page (1) and it works with an:

<iframe id="youtube_player" class="yt_player_iframe" width="640" height="360" src="http://www.youtube.com/embed/aHUBlv5_K8Y?enablejsapi=1&version=3&playerapiid=ytplayer"  allowfullscreen="true" allowscriptaccess="always" frameborder="0"></iframe>

and the following JS/jQuery code:

$('.yt_player_iframe').each(function(){
  this.contentWindow.postMessage('{"event":"command","func":"stopVideo","args":""}', '*')
});

If anyone is still looking for the answer, i've solved it like so:

$("#photos").on("hide",function(){
    var leg=$('.videoPlayer').attr("src");
    $('.videoPlayer').attr("src",leg);
});

Where #photos is the ID of the modal and .videoPlayer is the class of the iframe. Basically it refreshes the src attribute (and stops playing the video). So,

    $('#myStopClickButton').click(function(){
      $('.yvideo').each(function(){
        var el_src = $(this).attr("src");
        $(this).attr("src",el_src);
      });
    });

should do the trick.

$scope.stopVideo = function() {
 var iframe = document.getElementsByTagName("iframe")[0].contentWindow;
 iframe.postMessage('{"event":"command","func":"'+'stopVideo'+   '","args":""}', '*');
 }

Talvi's answer may still work, but that Youtube Javascript API has been marked as deprecated. You should now be using the newer Youtube IFrame API.

The documentation provides a few ways to accomplish video embedding, but for your goal, you'd include the following:

//load 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);

//will be youtube player references once API is loaded
var players = [];

//gets called once the player API has loaded
function onYouTubeIframeAPIReady() {
    $('.myiframeclass').each(function() {
        var frame = $(this);

        //create each instance using the individual iframe id
        var player = new YT.Player(frame.attr('id'));

        players.push(player);
    });
}

//global stop button click handler
$('#mybutton').click(function(){

    //loop through each Youtube player instance and call stopVideo()
    for (var i in players) {
        var player = players[i];
        player.stopVideo();
    }
});

Here is a codepen, it worked for me.

I was searching for the simplest solution for embedding the YT video within an iframe, and I feel this is it.

What I needed was to have the video appear in a modal window and stop playing when it was closed

Here is the code : (from: https://codepen.io/anon/pen/GBjqQr)

    <div><a href="#" class="play-video">Play Video</a></div>
    <div><a href="#" class="stop-video">Stop Video</a></div>
    <div><a href="#" class="pause-video">Pause Video</a></div>

    <iframe class="youtube-video" width="560" height="315" src="https://www.youtube.com/embed/glEiPXAYE-U?enablejsapi=1&version=3&playerapiid=ytplayer" frameborder="0" allowfullscreen></iframe>

$('a.play-video').click(function(){
    $('.youtube-video')[0].contentWindow.postMessage('{"event":"command","func":"' + 'playVideo' + '","args":""}', '*');
});

$('a.stop-video').click(function(){
    $('.youtube-video')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');
});

$('a.pause-video').click(function(){
    $('.youtube-video')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
});

Additionally, if you want it to autoplay in a DOM-object that is not yet visible, such as a modal window, if I used the same button to play the video that I was using to show the modal it would not work so I used THIS:

https://www.youtube.com/embed/EzAGZCPSOfg?autoplay=1&enablejsapi=1&version=3&playerapiid=ytplayer

Note: The ?autoplay=1& where it's placed and the use of the '&' before the next property to allow the pause to continue to work.

One cannot simply overestimate this post and answers thx OP and helpers. My solution with just video_id exchanging:

<div style="pointer-events: none;">
    <iframe id="myVideo" src="https://www.youtube.com/embed/video_id?rel=0&modestbranding=1&fs=0&controls=0&autoplay=1&showinfo=0&version=3&enablejsapi=1" width="560" height="315" frameborder="0"></iframe> </div>

    <button id="play">PLAY</button>

    <button id="pause">PAUSE</button>


    <script>
        $('#play').click(function() {
            $('#myVideo').each(function(){ 
                var frame = document.getElementById("myVideo");
                frame.contentWindow.postMessage(
                    '{"event":"command","func":"playVideo","args":""}', 
                    '*'); 
            });
        });

        $('#pause').click(function() {
            $('#myVideo').each(function(){ 
                var frame = document.getElementById("myVideo");
                frame.contentWindow.postMessage(
                  '{"event":"command","func":"pauseVideo","args":""}',
                  '*'); 
            });
        });
    </script>
