How to play multiple videos in html page

I want to play a video in a res of 720p (1280x720) with an autoplay and a loop whenever the video ends replace by another video in array.
the first video works fine, but it didn't autoplay, and after it end. it does not continue to play another video.
here's my code :
<div class="content-left">
<video controls id="myVideo" width="1280" height="720" autoplay></video>
<script>
var videoSource = new Array();
videoSource[0]='videos/bluevideo.mp4';
videoSource[1]='videos/redvideo.mp4';
videoSource[2]='videos/yellowvideo.mp4';
var videoCount = videoSource.length;
document.getElementById("myVideo").setAttribute("src",videoSource[0]);
function videoPlay(videoNum)
{
document.getElementById("myVideo").setAttribute("src",videoSource[videoNum]);
document.getElementById("myVideo").load();
document.getElementById("myVideo").play();
}
document.getElementById('myVideo').addEventListener('ended',myHandler,false);
function myHandler() {
i++;
if(i == (videoCount-1)){
i = 0;
videoPlay(i);
}
else{
videoPlay(i);
}
}
</script>
</div>
where did I do wrong? can anyone help me?thankyou very much.

You have a variable i which you increment in myHandler. However, it isn't declared anywhere. You should declare it outside the code of the event handler, and set the value to the first index:
var videoSource = new Array();
videoSource[0] = 'videos/bluevideo.mp4';
videoSource[1] = 'videos/redvideo.mp4';
videoSource[2] = 'videos/yellowvideo.mp4';
var videoCount = videoSource.length;
var i = 0;
document.getElementById("myVideo").setAttribute("src", videoSource[0]);
function videoPlay(videoNum) {
document.getElementById("myVideo").setAttribute("src", videoSource[videoNum]);
document.getElementById("myVideo").load();
document.getElementById("myVideo").play();
}
document.getElementById('myVideo').addEventListener('ended', myHandler, false);
function myHandler() {
i++;
if (i == videoCount) {
i = 0;
videoPlay(i);
} else {
videoPlay(i);
}
}

Play video in loop with different timing and function

I have 2 function which play the same video but with different timing.
I can't play make the function to work properly.
Looks like the function doesn't reset the other function
I tried to change variables names but still change the timing on click.
var video = document.getElementById('videoElm');
function playShortVideo() {
var starttime = 0; // start at 0 seconds
var endtime = 2; // stop at 2 seconds
video.addEventListener("timeupdate", function() {
if (this.currentTime >= endtime) {
this.currentTime = 0; // change time index here
}
}, false);
video.load();
video.play();
}
function playFullVideo() {
var starttime = 0; // start at 0 seconds
var endtime = 24; // stop at 2 seconds
video.addEventListener("timeupdate", function() {
if (this.currentTime >= endtime) {
this.currentTime = 0; // change time index here
}
}, false);
video.load();
video.play();
}
//play short video by default
playShortVideo();
//CLICK events
var btnshort = $('.shortvideo');
var btnfull = $('.fullvideo');
btnshort.click(function() {
playShortVideo();
});
btnfull.click(function() {
playFullVideo();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<video id="videoElm" autoplay muted controls loop>
<source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/webm">
</video>
</div>
<button class="shortvideo">play 2 secs only</a><br>
<button class="fullvideo">loop full video</button>

That's because the listener is still there, you need to remove it.
Remember, in order to remove it, you can't use anonymous function as callback so I turned it into defined function.
var video = document.getElementById('videoElm');
const playShort = function() {
if (this.currentTime >= 2) {
this.currentTime = 0; // change time index here
}
};
const playFull = function() {
if (this.currentTime >= 24) {
this.currentTime = 0; // change time index here
}
};
function playShortVideo() {
video.removeEventListener("timeupdate", playFull, false)
video.addEventListener("timeupdate", playShort, false);
video.load();
video.play();
}
function playFullVideo() {
video.removeEventListener("timeupdate", playShort, false)
video.addEventListener("timeupdate", playFull, false);
video.load();
video.play();
}
//play short video by default
playShortVideo();
//CLICK events
var btnshort = $('.shortvideo');
var btnfull = $('.fullvideo');
btnshort.click(function() {
playShortVideo();
});
btnfull.click(function() {
playFullVideo();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<video id="videoElm" autoplay muted controls loop>
<source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/webm">
</video>
</div>
<button class="shortvideo">play 2 secs only</a><br>
<button class="fullvideo">loop full video</button>
And here is the approach for starting the video at 49 sec (60 > 49 + 10)
const shortStartTime = 49;
const shortDuration = 10;
var video = document.getElementById('videoElm');
const playShort = function() {
if (this.currentTime > (shortStartTime + shortDuration)) {
this.currentTime = shortStartTime; // change time index here
}
};
const playFull = function() {
if (this.currentTime >= 24) {
this.currentTime = 0; // change time index here
}
};
function playShortVideo() {
video.removeEventListener("timeupdate", playFull, false)
video.addEventListener("timeupdate", playShort, false);
video.load();
video.currentTime = shortStartTime;
video.play();
}
function playFullVideo() {
video.removeEventListener("timeupdate", playShort, false)
video.addEventListener("timeupdate", playFull, false);
video.load();
video.play();
}
//play short video by default
playShortVideo();
//CLICK events
var btnshort = $('.shortvideo');
var btnfull = $('.fullvideo');
btnshort.click(function() {
playShortVideo();
});
btnfull.click(function() {
playFullVideo();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<video id="videoElm" autoplay muted controls loop>
<source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/webm">
</video>
</div>
<button class="shortvideo">play 2 secs only</a><br>
<button class="fullvideo">loop full video</button>

That happens because you're attaching a timeUpdate event listener multiple times.
You either need to use one-only or delete it before attaching a new one.
var video = document.getElementById('videoElm');
var listener;
var starttime = 0;
var endtime = 2;
function updateVideo(e) {
if (e.target.currentTime >= endtime) {
e.target.currentTime = 0; // change time index here
}
}
function playShortVideo() {
starttime = 0; // start at 0 seconds
endtime = 2; // stop at 2 seconds
if (!listener) {
listener = video.addEventListener("timeupdate", updateVideo, false);
}
video.load();
video.play();
}
function playFullVideo() {
starttime = 0; // start at 0 seconds
endtime = 24; // stop at 2 seconds
if (!listener) {
listener = video.addEventListener("timeupdate", updateVideo, false);
}
video.load();
video.play();
}
//play short video by default
playShortVideo();
//CLICK events
var btnshort = $('.shortvideo');
var btnfull = $('.fullvideo');
btnshort.click(function() {
playShortVideo();
});
btnfull.click(function() {
playFullVideo();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<video id="videoElm" autoplay muted controls loop>
<source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/webm">
</video>
</div>
<button class="shortvideo">play 2 secs only</a><br>
<button class="fullvideo">loop full video</button>

Change Video in Everyday

I have a some videos, that need to be play continuously. But there is a condition, first video should be play upto 24 hours.it means, loop the first video for 24 hours. after that next video. Now the videos are playing continuously. But I Don't know how to set the time for playing videos. Please help me to solve this problem. Thank you.
Here is My code.
var videoSources = ["video/kid.mp4", "video/hands.mp4", "video/video5.mp4", "video/action.mp4"];
var currentIndex = 0;
// listener function changes src
function myNewSrc() {
var myVideo = document.getElementsByClassName('episodeVideo')[0];
myVideo.src = videoSources[currentIndex];
myVideo.load();
}
// add a listener function to the ended event
function myAddListener() {
var myVideo = document.getElementsByClassName('episodeVideo')[0];
currentIndex = (currentIndex + 1) % videoSources.length;
myVideo.src = videoSources[currentIndex];
myVideo.addEventListener('ended', myNewSrc, false);
}
<div class="video-wrapper-main">
<video onended="myAddListener()" class="episodeVideo" preload="auto" autoplay controls>
<source src="" type="video/mp4">
</video>
</div>

var videoSources = ["video/kid.mp4", "video/hands.mp4", "video/video5.mp4", "video/action.mp4"];
var startTime = Date.now();
var currentIndex = 0;
// listener function changes src
function myNewSrc() {
var myVideo = document.getElementsByClassName('episodeVideo')[0];
var newTime = Date.now();
var msIn24Hours = 1000 * 60 * 60 * 24;
var isAfter24Hours = newTime - startTime >= msIn24Hours;
if(isAfter24Hours) {
myVideo.src = videoSources[currentIndex];
startTime = newTime;
}
myVideo.load();
}
// add a listener function to the ended event
function myAddListener() {
var myVideo = document.getElementsByClassName('episodeVideo')[0];
currentIndex = (currentIndex + 1) % videoSources.length;
myVideo.src = videoSources[currentIndex];
myVideo.addEventListener('ended', myNewSrc, false);
}
You could then store the start into localStorage and use that value.

Playlist with <audio> JavaScript

I'm creating a personal small website and I want to play some songs on it. What I've tried to do is the following:
<script type="text/javascript">
var i=1;
var nextSong= "";
var audioPlayer = document.getElementById('audio');
audioPlayer.onended = function(){
i++
nextSong = "Music/"+i+".mp3";
audioPlayer.src = nextSong;
audioPLayer.load();
audioPlayer.play();
if(i == 37) // this is the end of the songs.
{
i = 1;
}
}
</script>
<audio id="audio" src="Music/1.mp3"controls="controls" autoplay="autoplay" align=""> </audio>
However, I can't get this to work. It just plays the first song and doesn't execute the JS. I've tried alerting the state of i for example but it doesn't do anything.

Try this:
<script type="text/javascript">
var i=1;
var nextSong= "";
function setup() {
document.getElementById('audio').addEventListener('ended', function(){
i++;
nextSong = "Music/"+i+".mp3";
audioPlayer = document.getElementById('audio');
audioPlayer.src = nextSong;
audioPLayer.load();
audioPlayer.play();
if(i == 37) // this is the end of the songs.
{
i = 1;
}
}, false);
}
</script>
<body onLoad="setup();">
<audio id="audio" src="Music/1.mp3"controls="controls" autoplay="autoplay" align=""> </audio>
</body>

Amendment needed on this answer. You need to also identify the audio player, otherwise this won't work...
<script type="text/javascript">
function setup() {
var i=1;
var nextSong= "";
audioPlayer = document.getElementById('audio');
document.getElementById('audio').addEventListener('ended', function(){
i=i+1;
nextSong = "m"+i+".mp3";
audioPlayer.src = nextSong;
audioPlayer.load();
audioPlayer.play();
}, false);
}
</script>
<body onLoad="setup();">
<audio id="audio" src="m1.mp3" controls="controls" autoplay="autoplay" align=""> </audio>
</body>

var i=1; var nextSong= ""; function setup() { document.getElementById('audio').addEventListener('ended', function(){ i++; nextSong = "Music/"+i+".mp3"; audioPlayer = document.getElementById('audio'); audioPlayer.src = nextSong; audioPLayer.load(); audioPlayer.play(); if(i == 37) // this is the end of the songs. { i = 1; } }, false); }
