I have the following code that should mute audio when window is focused, but I must have done something wrong since it doesn't mute at all;
script
$(function() {
$(window).focus(function() {
console.log('Focus');
/*getElementById('notificationsound').muted = true;*/
$("#notificationsound").prop('muted', true); //mute
});
$(window).blur(function() {
console.log('Blur');
});
});
html
<audio id="notificationsound" src="sound/notify.mp3" preload="auto"></audio>
The goal is for the notification sound to be played only when the page is not viewed / out of focus (I'm using this "script structure" since it's likely I'll add more to the different states later on).
I know I'm missing something very basic since I'm a beginner, and since it logs focus/blur in the console correctly. Also – I know this most likely is a very similar question to others asked here before, but I could only find rather aged answers (which my code is based upon) so if this is not the "modern" or best practice anymore I'd love examples of alternate methods.
Examples are very much appreciated in case of major change is needed or suggested.
Try $("#notificationsound").prop('muted', true); - you missed the '#' which is the Id selector in JQuery.
$("#notificationsound").stop();
or
$("#notificationsound").pause();
$("#notificationsound").currentTime = 0;
Or even use JS:
var audio = new Audio('example.mp3');
which allows such functions:
audio.currentTime=1;
audio.play();
audio.stop();
audio.pause();
and even:
audio.volume = 0.5 //half

I am making a chrome extension that needs to know if a YouTube video is being played, paused, had a duration change, and if it is on an ad. I figured out how to do everything except knowing if it is on an advertisement. I found this post which was of some help, however, if I were to put this in my content script it would only run once and I want it to constantly check if there is an ad (since ads can happen in the middle of a video.
I am fairly new to Javascript, but I do understand the concepts of listeners and I would use a listener in this case, however, I do not know how to do that in this case because the div does not emit an event, it either exists or is null. Are there any other ways of doing that?
+1 to looking at YouTube video API events. Here's that page [0].
I haven't tried this myself, but I would start with the onStateChange event, because I suspect that an ad is a separate video from the desired video content itself. So there could be two "video cued" or "5" values fired. But, again, I haven't tried it myself. Good luck!

You can also use setInterval to detect ads continuously. This is a way without having to looking for API.
// According to the post you provided
function detectAds() {
return !!document.querySelector("div.ad-showing");
}
let timer;
function listen() {
timer = setInterval(function () {
if (detectAds()) { /* do something */ }
}, 1000); // runs every second
}
function unlisten() {
if (timer) clearInterval(timer);
}
I am playing a small audio clip on click of each link in my navigation
HTML Code:
<audio tabindex="0" id="beep-one" controls preload="auto" >
<source src="audio/Output 1-2.mp3">
<source src="audio/Output 1-2.ogg">
</audio>
JS code:
$('#links a').click(function(e) {
e.preventDefault();
var beepOne = $("#beep-one")[0];
beepOne.play();
});
It's working fine so far.
Issue is when a sound clip is already running and i click on any link nothing happens.
I tried to stop the already playing sound on click of link, but there is no direct event for that in HTML5's Audio API
I tried following code but it's not working
$.each($('audio'), function () {
$(this).stop();
});
Any suggestions please?
Instead of stop() you could try with:
sound.pause();
sound.currentTime = 0;
This should have the desired effect.
first you have to set an id for your audio element
in your js :
var ply = document.getElementById('player');
var oldSrc = ply.src;// just to remember the old source
ply.src = "";// to stop the player you have to replace the source with nothing
I was having same issue. A stop should stop the stream and onplay go to live if it is a radio. All solutions I saw had a disadvantage:
player.currentTime = 0 keeps downloading the stream.
player.src = '' raise error event
My solution:
var player = document.getElementById('radio');
player.pause();
player.src = player.src;
And the HTML
<audio src="http://radio-stream" id="radio" class="hidden" preload="none"></audio>
Here is my way of doing stop() method:
Somewhere in code:
audioCh1: document.createElement("audio");
and then in stop():
this.audioCh1.pause()
this.audioCh1.src = 'data:audio/wav;base64,UklGRiQAAABXQVZFZm10IBAAAAABAAEAVFYAAFRWAAABAAgAZGF0YQAAAAA=';
In this way we don`t produce additional request, the old one is cancelled and our audio element is in clean state (tested in Chrome and FF) :>
This method works:
audio.pause();
audio.currentTime = 0;
But if you don't want to have to write these two lines of code every time you stop an audio you could do one of two things. The second I think is the more appropriate one and I'm not sure why the "gods of javascript standards" have not made this standard.
First method: create a function and pass the audio
function stopAudio(audio) {
audio.pause();
audio.currentTime = 0;
}
//then using it:
stopAudio(audio);
Second method (favoured): extend the Audio class:
Audio.prototype.stop = function() {
this.pause();
this.currentTime = 0;
};
I have this in a javascript file I called "AudioPlus.js" which I include in my html before any script that will be dealing with audio.
Then you can call the stop function on audio objects:
audio.stop();
FINALLY CHROME ISSUE WITH "canplaythrough":
I have not tested this in all browsers but this is a problem I came across in Chrome. If you try to set currentTime on an audio that has a "canplaythrough" event listener attached to it then you will trigger that event again which can lead to undesirable results.
So the solution, similar to all cases when you have attached an event listener that you really want to make sure it is not triggered again, is to remove the event listener after the first call. Something like this:
//note using jquery to attach the event. You can use plain javascript as well of course.
$(audio).on("canplaythrough", function() {
$(this).off("canplaythrough");
// rest of the code ...
});
BONUS:
Note that you can add even more custom methods to the Audio class (or any native javascript class for that matter).
For example if you wanted a "restart" method that restarted the audio it could look something like:
Audio.prototype.restart= function() {
this.pause();
this.currentTime = 0;
this.play();
};
It doesn't work sometimes in chrome,
sound.pause();
sound.currentTime = 0;
just change like that,
sound.currentTime = 0;
sound.pause();
From my own javascript function to toggle Play/Pause - since I'm handling a radio stream, I wanted it to clear the buffer so that the listener does not end up coming out of sync with the radio station.
function playStream() {
var player = document.getElementById('player');
(player.paused == true) ? toggle(0) : toggle(1);
}
function toggle(state) {
var player = document.getElementById('player');
var link = document.getElementById('radio-link');
var src = "http://192.81.248.91:8159/;";
switch(state) {
case 0:
player.src = src;
player.load();
player.play();
link.innerHTML = 'Pause';
player_state = 1;
break;
case 1:
player.pause();
player.currentTime = 0;
player.src = '';
link.innerHTML = 'Play';
player_state = 0;
break;
}
}
Turns out, just clearing the currentTime doesn't cut it under Chrome, needed to clear the source too and load it back in. Hope this helps.
As a side note and because I was recently using the stop method provided in the accepted answer, according to this link:
https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Media_events
by setting currentTime manually one may fire the 'canplaythrough' event on the audio element. In the link it mentions Firefox, but I encountered this event firing after setting currentTime manually on Chrome. So if you have behavior attached to this event you might end up in an audio loop.

This is indeed what will happen, and pausing will also trigger the pause event, both of which make this technique unsuitable for use as a "stop" method. Moreover, setting the src as suggested by zaki will make the player try to load the current page's URL as a media file (and fail) if autoplay is enabled - setting src to null is not allowed; it will always be treated as a URL. Short of destroying the player object there seems to be no good way of providing a "stop" method, so I would suggest just dropping the dedicated stop button and providing pause and skip back buttons instead - a stop button wouldn't really add any functionality.
This approach is "brute force", but it works assuming using jQuery is "allowed". Surround your "player" <audio></audio> tags with a div (here with an id of "plHolder").
<div id="plHolder">
<audio controls id="player">
...
</audio>
<div>
Then this javascript should work:
function stopAudio() {
var savePlayer = $('#plHolder').html(); // Save player code
$('#player').remove(); // Remove player from DOM
$('#FlHolder').html(savePlayer); // Restore it
}
I was looking for something similar due to making an application that could be used to layer sounds with each other for focus. What I ended up doing was - when selecting a sound, create the audio element with Javascript:
const audio = document.createElement('audio') as HTMLAudioElement;
audio.src = getSoundURL(clickedTrackId);
audio.id = `${clickedTrackId}-audio`;
console.log(audio.id);
audio.volume = 20/100;
audio.load();
audio.play();
Then, append child to document to actually surface the audio element
document.body.appendChild(audio);
Finally, when unselecting audio, you can stop and remove the audio element altogether - this will also stop streaming.
const audio = document.getElementById(`${clickedTrackId}-audio`) as HTMLAudioElement;
audio.pause();
audio.remove();
If you have several audio players on your site and you like to pause all of them:
$('audio').each( function() {
$(this)[0].pause();
});
I believe it would be good to check if the audio is playing state and reset the currentTime property.
if (sound.currentTime !== 0 && (sound.currentTime > 0 && sound.currentTime < sound.duration) {
sound.currentTime = 0;
}
sound.play();
for me that code working fine. (IE10+)
var Wmp = document.getElementById("MediaPlayer");
Wmp.controls.stop();
<object classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6"
standby="Loading áudio..." style="width: 100%; height: 170px" id="MediaPlayer">...
Hope this help.
What I like to do is completely remove the control using Angular2 then it's reloaded when the next song has an audio path:
<audio id="audioplayer" *ngIf="song?.audio_path">
Then when I want to unload it in code I do this:
this.song = Object.assign({},this.song,{audio_path: null});
When the next song is assigned, the control gets completely recreated from scratch:
this.song = this.songOnDeck;
The simple way to get around this error is to catch the error.
audioElement.play() returns a promise, so the following code with a .catch() should suffice manage this issue:
function playSound(sound) {
sfx.pause();
sfx.currentTime = 0;
sfx.src = sound;
sfx.play().catch(e => e);
}
Note: You may want to replace the arrow function with an anonymous function for backward compatibility.
In IE 11 I used combined variant:
player.currentTime = 0;
player.pause();
player.currentTime = 0;
Only 2 times repeat prevents IE from continuing loading media stream after pause() and flooding a disk by that.
What's wrong with simply this?
audio.load()
As stated by the spec and on MDN, respectively:
Playback of any previously playing media resource for this element stops.
Calling load() aborts all ongoing operations involving this media element
Hello stackovercool community,
I'm trying to set a sound player on my site and display the title of the track in the footer. So far so good but I'd like to mute the music when clicking on the text title. I'd also liked to change the opacity of the text when paused.
I'm sorry my JS knowledge lacks, exactly, of knowledge. I tried this after various research but doesn't works.
function play(idPlayer) {
var player = document.querySelector('#' + idPlayer);
if (player.played) {
player.pause();
player.style.opacity = "0.5";
} else {
player.play();
player.style.opacity = "1";
}
}

Here's the working answer if anyone wants something similar.
Still doesn't works on my wordpress though, I think because of
var $j = jQuery.noConflict(); $j(document).ready(function()
I think the question is solved then.
I'm wondering how to stop the MediaElement.js player at the end of the video. I wondered how to stop the mediaelement.js player at the end of a video. I was hoping to hold on the last frame and not rewind to show the first frame as it does now.
Is it possible to change this behaviour?
I wrote a fix for this problem and John merged in version 2.10.2.
There is now an option "autoRewind" that you can set to false to prevent the player from going back to the beginning.
The eventlistener is not added and there is no more need to remove it.
$('video').mediaelementplayer({
autoRewind: false
});
I believe that the default behavior of the <video> element is to go back to the beginning so you'd just need to override this by listening for the ended event.
var player = $('#myvideo').mediaelementplayer();
player.media.addEventListener('ended', function(e) {
player.media.setCurrentTime(player.media.duration);
}, false);
Hope that helps!
Probably the best solution is not to be afraid and remove the "rewind-to-start-on-video-end" handler from mediaelement source.
If you go into the source code for mediaelement and search for "ended", you'll eventually see, that rewinding after reaching end of the video is actually done deliberately by mediaelement.
If you want to remove that functionality feel free to just remove that handler for "ended" event from mediaelement source. That solves all the problems, including flickering between last and first frame, mentioned in some other answers to this question.
The code in John Dyer's answer didn't really work for me either for some reason. I was however able to get this version working...
var videoPlayer = new MediaElementPlayer('#homepage-player', {
loop: false,
features:[],
enablePluginDebug: false,
plugins: ['flash','silverlight'],
pluginPath: '/js/mediaelement/',
flashName: 'flashmediaelement.swf',
silverlightName: 'silverlightmediaelement.xap',
success: function (mediaElement, domObject) {
// add event listener
mediaElement.addEventListener('ended', function(e) {
mediaElement.pause();
mediaElement.setCurrentTime(mediaElement.duration);
}, false);
},
error: function () {
}
});
videoPlayer.play();
The only problem I'm having - which is very frustrating, is it is flickering between the LAST and FIRST frames in Chrome. Otherwise, it works as expected in Firefox and IE...
This problem i faced when playing audio files
The problem is in the play, when you pause your player the file will stop but before resuming you have to decrease the current time of the player by any value in your case you may decrease it by a frame maybe
after setting your source ,loading your file and pausing, then
myplayer.player.play();
var currentTime = myplayer.player.getCurrentTime();
myplayer.player.setCurrentTime(currentTime-0.1);
myplayer.player.setCurrentRail();
I've got a page with links to MP3s, when the link is clicked I use javascript to show a small Flash player (NiftyPlayer) under the link. When a different link is clicked, the old player is hidden and the new player is revealed.
The player auto-starts when the element is shown, and auto-stops when hidden - in Firefox.
In IE it will only auto-start and NOT auto-stop. This is what I would like to solve.
This is an example HTML with link and player
Misunderstood What You Said
<div id="player662431" class="playerhide"><embed src="http://www.example.com/shop/flash/player.swf?file=/mp3/Beat The Radar - Misunderstood What You Said.mp3&as=1" quality="high" bgcolor="#000000" width="161" height="13" name="niftyPlayer662431" align="" type="application/x-shockwave-flash" swLiveConnect="true" pluginspage="http://www.macromedia.com/go/getflashplayer"></embed>
Here is the javascript (I've got jQuery installed to let me hide all the open players on this page apart from the new one)
function toggle_visibility(id) {
$('.playerhide').hide();
var e = document.getElementById(id);
e.style.display = 'block';
}
I think what I need to do is start the player manually with javascript (rather than using the autostart as=1 function in the URL string)
There is some javascript that comes with NiftyPlayer to allow this EG
niftyplayer('niftyPlayer1').play()
there is also a stop method.
I need some help with javascript - how do I add this call to play into my toggle_visibility function (it has the same unique ID number added to the name of the player as the ID of the div that's being shown, but I don't know how to pull this ID number out of one thing and put it in another)
I also would like to be able to do
niftyplayer('niftyPlayer1').stop()
to stop the audio of the previously running player. Is it possible to store the current ID number somewhere and call it back when needed?
Thanks for the help, i'm a PHP programmer who needs some support with Javascript - I know what I want to achieve, just don't know the commands to do it!
Thanks
If you assigned each niftyplayer object a classname, f.x. ".players", then you could loop through each player, like this:
function toggle_visibility(id) {
$(".players").each(function(){
playerId = $(this).attr('id');
if(niftyplayer(playerId).getState() == 'playing') {
//Stop the currently playing player
niftyplayer(playerId).stop();
//Hide the div that was playing
$("#" + playerId).hide();
}
});
//Start the new player
niftyplayer(id).play();
$("#" + id).show();
}
So what this actually does, is it loops through all the players on the website. It checks if the status of each player is equal to "playing", if it is, then it stops it and hides the div tags. Then it starts the new player and shows that div tag.
I think this does it. Try it out.
I have a much better solution after I noticed a very nasty bug / 'feature' when using Internet Explorer in conjunction.
I had noticed that in IE the pages were taking a very long time to load when I had a lot of hidden Nifty Players, I looked closer using Fiddler and found that each instance of NiftyPlayer was preloading the MP3 in full, rather than loading on demand as with Firefox and Chrome etc.
This meant that a page with 100 items (each item having up to 4 MP3s) took several minutes to load at times with obvious data transfer implications.
My solution which is rather simpler (but maybe clunkier) than Indyber's is to just use
function toggle_visibility(id,mp3location) {
// hide all players
$(".playerarea").html('');
// show clicked player
$('#' + id).html('<embed src=\"http://www.xxx.com/shop/flash/player.swf?file=http://www.xxx.com/mp3/' + decodeURIComponent(mp3location) + '.mp3&as=1\" quality=high bgcolor=#000000 WMODE=transparent width=\"161\" height=\"13\" align=\"\" type=\"application/x-shockwave-flash\" swLiveConnect=\"true\" pluginspage=\"http://www.macromedia.com/go/getflashplayer\" class=\"playerNew\">');
}
which works fine with IE, and also solves the problem of not being able to stop the players from playing in IE
