How can I track HTML5 Video Control event? - javascript

I'm trying to track the event of an HTML5 Video, specifically the pause/play on the default control bar (for non-mobile Chrome and Safari).
Here's my test code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Video Test</title>
</head>
<body>
<video id="video" width="320" height="240" src="http://www.w3schools.com/tags/mov_bbb.mp4" controls>
<source src="http://www.w3schools.com/tags/mov_bbb.mp4" type="video/mp4">
</video>
<script>
var video = document.getElementById("video");
video.onclick = function(){
if(!this.paused) {
this.pause();
console.log("paused");
} else {
this.play();
console.log("playing");
}
}
</script>
</body>
</html>
If I toggle play/pause in the center of the video, the event fires just fine.
The problem is that when I click the Pause/Play button on the default control bar (lower left), although the video pauses/plays, the log does not display (I assume the event does fire since it pauses/plays).
I've not found a reason for the log to not display and was hoping someone to point me in the right direction.
In my actual code, depending on whether the video is paused or played, a timer function will be called (or killed).
Thanks.

Your adding the onclick event to pause and resume the video but you're not handling the pause and playing events. Those events are triggered when you pause an play from the control bar.
This is how I would do it:
var video = document.getElementById("video");
function StartPauseHandler(e) {
if (e.type === "pause") {
console.log("paused");
} else if (e.type === "playing") {
console.log("playing");
} else {
if(!this.paused) {
this.pause();
} else {
this.play();;
}
}
}
video.addEventListener("click", StartPauseHandler);
video.addEventListener("pause", StartPauseHandler);
video.addEventListener("playing", StartPauseHandler);

play/pause video onclick firefox

I want videos to play/pause when you click on them. Firefox has this behaviour by default. Chrome does not. The simple solution I came up with was setting a click event with jQuery.
var video = $('#myVideo');
var videoDomObj = video.get(0);
//click event for the video itself
video.on('click', function(e){
//when video is clicked it should be paused when playing and vise versa
if (videoDomObj.paused){
videoDomObj.play();
} else{
videoDomObj.pause();
}
});
jsfiddle
This will work in IE and Chrome. However, this will result in a conflict in Firefox, since it will instantly call the default event afterwards and will not play the video at all. e.preventDefault() fixes this problem, but will break all the other controls in Firefox. While they still work, they will play/pause the video. Is there an easy solution for this?
In fact the raw code worked like a charm:
document.getElementById('myVideo').onclick = function(e) {
e.preventDefault();
if (this.paused){
this.play();
} else{
this.pause();
}
}
The jQuery equivalent should be:
jQuery('#myVideo').on('click', function(e) {
e.preventDefault();
if (this.paused){
this.play();
} else{
this.pause();
}
});
But as you said that breaks the video controlls, desired and simplest solution for this could be selecting a parent element (or adding a container, if required):
var video = document.getElementById('myVideo');
video.parentElement.onclick = function(e) {
if (video.paused){
video.play();
} else{
video.pause();
}
}
jQuery:
var $video = jQuery('#myVideo'), video = $video.get(0);
$video.parent().on('click', function(e) {
if (video.paused){
video.play();
} else{
video.pause();
}
});
The only solution I found was to detect the browser for this special case, since the problem only occurs in firefox and it has this feature by default anyway.
jsfiddle
//jQuery video element
var video = $('#myVideo');
//DOM element for HTML5 media events
var videoDomObj = video.get(0);
//detect if firefox
var is_firefox = navigator.userAgent.toLowerCase().indexOf('firefox') > -1;
//only bind click event if not firefox to prevent broken controls - firefox pauses/plays videos on click by default anyway
if (!is_firefox){
video.on('click', function(e){
//when video is clicked it should be paused when playing and vise versa
if (videoDomObj.paused){
videoDomObj.play();
} else{
videoDomObj.pause();
}
});
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<video id="myVideo" width="100%" controls>
<source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">

unable to pause video via jquery in mobile

Below is code i am using to play and pause video, it works fine in my desktop
when we click vidoe it opens and plays in fullscreen when press again vidoe should get paused with alert messaged pause .
when i play it in my andorid browser unable to get alert message

Js code:
/* Write JavaScript here */
$(document).ready(function() {
var v = document.getElementById("myVideo");
$('#myVideo').on('click', v, function (e) {
if (v.paused === false) {
v.pause();
alert("pause");
} else {
v.webkitEnterFullscreen();
v.play();
}
return false;
});
});
html code:
<script src="http://code.jquery.com/jquery-1.11.2.min.js"></script>
<video width="80%" height="auto" controls="controls" id="myVideo">
<source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4" />
</video>
Isn't it a problem with touch even handling? Maybe you should consider adding touch support to your script? Like that:
$('#myVideo').on('touchstart click', ...
You should then remember to stop propagation (remove ghost clicking) with:
e.stopPropagation();
In future you can also check if you're in mobile or not with:
if(e.type == "touchstart") {
// Handle touchstart event.
} else if(e.type == "click") {
// Handle click event.
}
http://jsfiddle.net/Lhzyggqn/
You can also check if you're in mobile in this way:
var clickHandler = ('ontouchstart' in document.documentElement ? "touchstart" : "click");

Show poster image or pause button when HTML5 video is paused?

Hi I'm coding a local site for an iPad and have a video without controls that plays and pauses when clicked on. Is it possible to show the poster image when the video is paused? Or show a pause button in the center? Here's the code I have for playing and pausing:
<script type='text/javascript'>//<![CDATA[
window.onload=function(){
var overlay = document.getElementById('video-overlay');
var video = document.getElementById('video');
var videoPlaying = false;
overlay.onclick = function() {
if (videoPlaying) {
video.pause();
videoPlaying = false;
}
else {
video.play();
videoPlaying = true;
}
}
}//]]>
</script>
and the HTML for the video
<div id='video-overlay'></div>
<video width="768" height="432" poster="thumbnail2.jpg" id='video'>
<source src="PhantomFuse3_TechVideo_h264.mp4" type="video/mp4">
</video>
Another solution is to call:
video.load()
It will redisplay the poster image. it will restart the video on next interaction, but you can save the time stamp and start playing from there if you wish.
You will have to register pause event on the video.
Something like this:
JSFiddle code
Of course you should modify this for your needs and add some structure. Haven't tried it on iPad though. Also to note: registering click will introduce 300ms lag on tap event. You should look at touchstart event for touch devices and register both click and touchstart.
var overlay = document.getElementById('video-overlay'),
video = document.getElementById('video'),
videoPlaying = false;
function hideOverlay() {
overlay.style.display = "none";
videoPlaying = true;
video.play();
}
function showOverlay() {
// this check is to differentiate seek and actual pause
if (video.readyState === 4) {
overlay.style.display = "block";
videoPlaying = true;
}
}
video.addEventListener('pause', showOverlay);
overlay.addEventListener('click', hideOverlay);

want to play audio and it should be stop after 10 seconds inHtml and javascript?

I am new in Html5 and javascript I want to play audio clip when i open html page and it should be stop after 10 seconds and display message that Audio play successfully.
for simple audio play in html5 as below
<!DOCTYPE html>
<html>
<body>
<audio controls>
<source src="kill_bill.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
<script>
setInterval(function(), 10000);
$.each($('audio'), function () { this.stop(); alert('Audio Stop Successfully'); });
</script>
</body>
</html>
A setTimeout seems more appropriate :
var audio = document.createElement("audio");
audio.src = "sound.mp3";
audio.addEventListener("canplaythrough", function () {
setTimeout(function(){
audio.pause();
alert("Audio Stop Successfully");
},
10000);
}, false);
Example
Put timer/counter on load of JS as it come to 10 seconds call the below function.
Timer
setInterval(Call Below Function, 10000)
Stop Audio
$.each($('audio'), function () {
this.stop();
alert('Audio Stop Successfully');
});
TRY THIS ::::
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>TIMER</title>
</head>
<body>
<audio id="aud" controls autoplay>
<source src="test.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
<script type="text/javascript">
var myaud = document.getElementById("aud");
var k = setInterval("pauseAud()", 10000);
function playAud() {
myaud.play();
}
function pauseAud() {
myaud.pause();
alert('Audio Stop Successfully');
clearInterval(k);
}
</script>
</body>
</html>
First of all, pay attention: automatic play won't work under iOS; as Apple prevents it to be possible.
As for stopping audio, I always suggest to use mediaelement library, which supports non HTML5 browsers and has a complete interface to start/stop audio playback.
<audio id="audio_killbill" muted controls onload="audiofor_10sec()">
<source src="kill_bill.mp3.mp3"></source> <!-- Webkit Browser -->
<source src="kill_bill.mp3.ogg"></source> <!-- Mozilla/Firefox -->
Your browser isn't invited for super fun <code>audio</code> time.
</audio>
Vanilla JS
function audiofor_10sec(){
let audio = getElementById('audio_killbill');
audio.muted = false; // New browser rule doesn't lets audio play automatically
audio.play();
setTimeout(() => {
audio.pause();
audio.currentTime = 0; // Works as audio stop
}, 10000);
}

Detect if HTML5 Video element is playing [duplicate]

This question already has answers here:
How to tell if a <video> element is currently playing?
(7 answers)
Closed 1 year ago.
I've looked through a couple of questions to find out if an HTML5 element is playing, but can't find the answer. I've looked at the W3 documentation and it has an event named "playing" but I can't seem to get it to work.
This is my current code:
var stream = document.getElementsByTagName('video');
function pauseStream() {
if (stream.playing) {
for (var i = 0; i < stream.length; i++) {
stream[i].pause();
$("body > header").addClass("paused_note");
$(".paused_note").text("Stream Paused");
$('.paused_note').css("opacity", "1");
}
}
}
It seems to me like you could just check for !stream.paused.
Check my answer at How to tell if a <video> element is currently playing?: MediaElement does not have a property that tells if it is playing or not. But you could define a custom property for it.
Object.defineProperty(HTMLMediaElement.prototype, 'playing', {
get: function(){
return !!(this.currentTime > 0 && !this.paused && !this.ended && this.readyState > 2);
}
})
Now you can use it on video or audio elements like this:
if(document.querySelector('video').playing){
// Do anything you want to
}
Note : This answer was given in 2011. Please check the updated documentation on HTML5 video before proceeding.
If you just want to know whether the video is paused, use the flag stream.paused.
There is no property for a video element in getting its playing status. But there is one event "playing" which will be triggered when it starts to play. An Event called "ended" is also triggered when it stops playing.
So the solution is:
Declare one variable videoStatus.
Add event handlers for different events of video.
Update videoStatus using the event handlers.
Use videoStatus to identify the status of the video.
This page will give you a better idea about video events. Play the video on this page and see how the events are triggered.
http://www.w3.org/2010/05/video/mediaevents.html
jQuery(document).on('click', 'video', function(){
if (this.paused) {
this.play();
} else {
this.pause();
}
});
Add eventlisteners to your media element. Possible events that can be triggered are: Audio and video media events
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Html5 media events</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
</head>
<body >
<div id="output"></div>
<video id="myVideo" width="320" height="176" controls autoplay>
<source src="http://www.w3schools.com/tags/mov_bbb.mp4" type="video/mp4">
<source src="http://www.w3schools.com/tags/mov_bbb.ogg" type="video/ogg">
</video>
<script>
var media = document.getElementById('myVideo');
// Playing event
media.addEventListener("playing", function() {
$("#output").html("Playing event triggered");
});
// Pause event
media.addEventListener("pause", function() {
$("#output").html("Pause event triggered");
});
// Seeking event
media.addEventListener("seeking", function() {
$("#output").html("Seeking event triggered");
});
// Volume changed event
media.addEventListener("volumechange", function(e) {
$("#output").html("Volumechange event triggered");
});
</script>
</body>
</html>
Best approach:
function playPauseThisVideo(this_video_id) {
var this_video = document.getElementById(this_video_id);
if (this_video.paused) {
console.log("VIDEO IS PAUSED");
} else {
console.log("VIDEO IS PLAYING");
}
}
I encountered a similar problem where I was not able to add event listeners to the player until after it had already started playing, so #Diode's method unfortunately would not work. My solution was check if the player's "paused" property was set to true or not. This works because "paused" is set to true even before the video ever starts playing and after it ends, not just when a user has clicked "pause".
You can use 'playing' event listener =>
const video = document.querySelector('#myVideo');
video.addEventListener("playing", function () {
// Write Your Code
});
Here is what we are using at http://www.develop.com/webcasts to keep people from accidentally leaving the page while a video is playing or paused.
$(document).ready(function() {
var video = $("video#webcast_video");
if (video.length <= 0) {
return;
}
window.onbeforeunload = function () {
var htmlVideo = video[0];
if (htmlVideo.currentTime < 0.01 || htmlVideo.ended) {
return null;
}
return "Leaving this page will stop your video.";
};
}
a bit example
var audio = new Audio('https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3')
if (audio.paused) {
audio.play()
} else {
audio.pause()
}
I just looked at the link #tracevipin added (http://www.w3.org/2010/05/video/mediaevents.html), and I saw a property named "paused".
I have ust tested it and it works just fine.
This is my code - by calling the function play() the video plays or pauses and the button image is changed.
By calling the function volume() the volume is turned on/off and the button image also changes.
function play() {
var video = document.getElementById('slidevideo');
if (video.paused) {
video.play()
play_img.src = 'img/pause.png';
}
else {
video.pause()
play_img.src = 'img/play.png';
}
}
function volume() {
var video = document.getElementById('slidevideo');
var img = document.getElementById('volume_img');
if (video.volume > 0) {
video.volume = 0
volume_img.src = 'img/volume_off.png';
}
else {
video.volume = 1
volume_img.src = 'img/volume_on.png';
}
}
I just did it very simply using onpause and onplay properties of the html video tag. Create some javascript function to toggle a global variable so that the page knows the status of the video for other functions.
Javascript below:
// onPause function
function videoPause() {
videoPlaying = 0;
}
// onPause function
function videoPlay() {
videoPlaying = 1;
}
Html video tag:
<video id="mainVideo" width="660" controls onplay="videoPlay();" onpause="videoPause();" >
<source src="video/myvideo.mp4" type="video/mp4">
</video>
than you can use onclick javascript to do something depending on the status variable in this case videoPlaying.
hope this helps...
My requirement was to click on the video and pause if it was playing or play if it was paused. This worked for me.
<video id="myVideo" #elem width="320" height="176" autoplay (click)="playIfPaused(elem)">
<source src="your source" type="video/mp4">
</video>
inside app.component.ts
playIfPaused(file){
file.paused ? file.play(): file.pause();
}
var video_switch = 0;
function play() {
var media = document.getElementById('video');
if (video_switch == 0)
{
media.play();
video_switch = 1;
}
else if (video_switch == 1)
{
media.pause();
video_switch = 0;
}
}
I just added that to the media object manually
let media = document.querySelector('.my-video');
media.isplaying = false;
...
if(media.isplaying) //do something
Then just toggle it when i hit play or pause.
a bit example when playing video
let v = document.getElementById('video-plan');
v.onplay = function() {
console.log('Start video')
};
