How to change video source with just JavaScript

Question

Here is my simple page (css not added):

<a onclick="PlayVideo('http://www.myhost.com/..../myVideo1.mp4');">Play Video 1</a>
<a onclick="PlayVideo('http://www.myhost.com/..../myVideo2.mp4');">Play Video 2</a>

<div id="xxxxxx">
    <div><a onclick="StopVideo();">X</a>
         <video id="video" width="520" height="360" controls></video>
    </div>
</div>


<script>
    function PlayVideo(srcVideo) {
        var video = document.getElementById('video');
        var source = document.createElement('source');   
        source.setAttribute('src', srcVideo);
        video.appendChild(source);
        video.play();
    }

    function StopVideo() {
        document.getElementById('video').pause();
    }
</script>

When I click "Play Video 2" it's still playing video 1. So how do I switch the video source to play in same video element? I need just pure JavaScript if that's possible

Answer 1

You do not need to append new source. Just set new src attribute and call video.load function.

See working JSFiddle

video = document.getElementById('video');
source = document.getElementById('source');

function PlayVideo(srcVideo){
  video.pause();
  source.src = srcVideo;
  video.load();
  video.play();
}

function StopVideo(){
  document.getElementById('video').pause();
}

EDIT: Changed .setAttribute('src',srcVideo) to .src = srcVideo because this is commonly used method to change source.
