Javascript, pausing audio in function - javascript

I have created a game that acts as a showcase for my portfolio.
However I want the audio to pause when a certain function is called
var aud = document.getElementById("#music");
I created a variable that acts as the stand in for the music
function web(i){
aud.pause(); //I try to pause the variable here
keysPressed = {};
if (!jumping){$("#guy").css({"background-image":"url(img/Character-Stand.gif)"});}
window.open(pickup[i].weblink);
};
I don't know what I have done wrong, any help would be appreciated.

Your code doesn't say exactly where you initalize your var aud = document.getElementById("#music"); and also not how you define your audio-tag. But below I have a minimal working example how to pause an audio.
<html>
<body>
<script>
function pause() {
var aud = document.getElementById("myAudio");
aud.pause();
}
</script>
<audio id="myAudio" controls>
<source src="audio.mp3" type="audio/mpeg">
</audio>
<button onclick="pause()">pause</button>
</body>
</html>

Video duration is sometimes NaN [duplicate]

Accessing an HTML5 audio element (a .ogg file) with JavaScript in Chrome. The file does play properly, yet somehow it will not recognize the duration.
I just cribbed this code: https://www.w3schools.com/jsref/prop_audio_duration.asp (I know w3schools isn't great, but it seems like something else is the problem...)
var x = document.getElementById("testTone").duration;
console.log("duration:"+x); // duration:NaN
var y = document.getElementById("testTone");
y.play(); // works!
the element...
<audio controls id="testTone">
<source src="autoharp/tone0.ogg" type="audio/ogg">
</audio>
Add preload="metadata" to your tag to have it request the metadata for your audio object:
<audio controls id="testTone" preload="metadata">
<source src="autoharp/tone0.ogg" type="audio/ogg">
</audio>
In your code, attach an event handler, to set the duration when the metadata has been loaded:
var au = document.getElementById("testTone");
au.onloadedmetadata = function() {
console.log(au.duration)
};
Beside #FrankerZ's solution, you could also do the following:
<audio controls id="testTone">
<source src="https://www.w3schools.com/jsref/horse.ogg" type="audio/ogg">
<source src="https://www.w3schools.com/jsref/horse.mp3" type="audio/mpeg">
</audio>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction() {
var x = document.getElementById("testTone").duration;
console.log("duration:" + x); // duration:NaN
var y = document.getElementById("testTone");
y.play(); // works!
}
</script>
you can try this..hope it will work i used this in 'timeupdate' event as i was getting same NaN error.
var x = document.getElementById("testTone").duration;
if(x){
console.log("duration:"+x);
}

Audio not playing in HTML using <script> tag

I'm trying to get an audio file to play in the background and it isn't working, any insight on it?
<audio id="bgmusic" preload hidden loop src="music.mp3"></audio>
<script>
function Play() {
var $audio = $('#bgmusic');
$audio.get(0).play();
}
</script>
Try
<audio id="bgmusic" preload hidden loop src="music.mp3"></audio>
<script>
function Play() {
var audio = "music.mp3";
audio.play();
}
</script>

JavaScript html5 video

I have a sample html5 video with simple html code.
What I need to do is a customized mute button for all the videos, meaning:
if the user clicks on the mute/unmute button for one video, all the other videos get muted/unmuted as well
Is there any way of doing this?
without your html code it is pretty vague but in JS you can do it :
here is a link of the documentation im using :
https://www.w3schools.com/tags/av_prop_muted.asp
https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_av_prop_muted
<button onclick="enableMute()" type="button">Mute sound</button>
<button onclick="disableMute()" type="button">Enable sound</button>
<video id="myVideo" width="320" height="176" controls>
<source src="mov_bbb.mp4" type="video/mp4">
<source src="mov_bbb.ogg" type="video/ogg">
Your browser does not support HTML5 video.
</video>
<script>
var vid = document.getElementById("myVideo");
function enableMute() {
vid.muted = true;
}
function disableMute() {
vid.muted = false;
}
</script>
So to trigger the action on all your videos you can :
add a class preferably or id on all your video tag
make js know about them
var vid = document.getElementById("myVideo");
var vid1 = document.getElementById("myVideo1");
var vid2 = document.getElementById("myVideo2");
var vid3 = document.getElementById("myVideo3");
var vid4 = document.getElementById("myVideo4");
add an onClick action on a button that trigger an action here Mute action which will mute or unmute your videos using the mute property of your element, the action would like
function enableMute() {
vid.muted = true;
vid1.muted = true;
vid2.muted = true;
vid3.muted = true;
vid4.muted = true;
}
I think you could do it without this much duplication of code if you add the same class to all your element, and looping through all of them in the action you trigger when you click on the button and then change for each of them their property but not sure exactly how to do it

Change audio file on button click

I am trying to change the audio file on a button click and am getting the error
Uncaught TypeError: audio.load is not a function
My code is below, the idea is to press the button and then the audio file will change.
Without the audio.load() line, the code will run and the src will update, but the audio does not change. What am I missing?
HTML:
<!DOCTYPE HTML>
<html>
<body>
<br>
<audio controls>
<source src = "audio_file_1.mp3"
id="audio" type="audio/mpeg">
Your browser does not support the audio element!
</audio>
<br>
<button onClick="changeAudio();">Change</button>
</body>
<script src="temp.js"></script>
</html>
Javascript:
// temp js
var a = 1;
function changeAudio() {
var audio = document.getElementById('audio');
if (a==1) {
audio.src = 'audio_file_1.mp3';
a = 2;
}
else {
audio.src = 'audio_file_2.mp3';
a = 1;
}
audio.load();
}
changeAudio();
(also, if anyone knows example sound files that I can use instead of the audio_file_1.mp3 and audio_file_2.mp3, I would be happy to update the code so anyone can run it more easily)
Edit WRT Rob M's answer:
For anyone with the same problem, the solution is to change two lines:
First, in the HTML code, the <audio control> should turn to <audio control id="audio_id">
Second, in the javascript code the audio.load() should turn to document.getElementById('audio_id').load();
There is no .load() event on a <source> tag, it is on the <audio> tag - update your code to call load() on the parent <audio> tag and it should work.
Well, I think you are trying to access to <audio> element by its id attribute, but you haven't set id attribute to audio tag.
It must be something like this
<audio id="audio" controls>
<source src = "audio_file_1.mp3"
id="track" type="audio/mpeg">
Your browser does not support the audio element!
</audio>
And changing audio file:
var a = 1;
function changeAudio() {
var audio = document.getElementById('audio');
if (a==1) {
document.getElementById('track') = 'audio_file_1.mp3';
a = 2;
}
else {
document.getElementById('track') = 'audio_file_2.mp3';
a = 1;
}
audio.load();
}
changeAudio();

2 audio sounds and I want to play one HTML5 audio element at a time

Question: I have 2 audio sounds and I want to play one HTML5 audio element at a time.
Similar Post: Play one HTML audio element at a time.
I saw a similar post to my question. However, as a JavaScript beginner I did not understand the code. So I tried a simpler way so I can understand, but is not working. I would appreciate any suggestions.
HTML5 code: (For this example only I used the same audio source as a previous post: http://jsfiddle.net/RE006/8djstmvy/
<div>
<h2>Example 1</h2>
<audio id="sound1" src=http://geo-samples.beatport.com/lofi/5005876.LOFI.mp3 controls="controls" preload="none">
<p>Your browser does not support the audio element.</p>
</audio>
</div>
<div>
<h2>Example 2</h2>
<audio id="sound2" src=http://geo-samples.beatport.com/lofi/5005933.LOFI.mp3 controls="controls" preload="none">
<p>Your browser does not support the audio element.</p>
</audio>
</div>
JavaScript:
var $ = function (id) {
return document.getElementById(id);
}
var sound1_click = function() {
//starts playing
$("sound1").play ();
//pause playing
$("sound2").pause();
}
var sound2_click = function() {
//starts playing
$("sound2").play ();
//pause playing
$("sound1").pause();
}
window.onload = function () {
$("sound1").onclick = sound1_click;
$("sound2").onclick = sound2_click;
}
I think the problem is you are listing to click event, when you should be listening to play event, also for some reason, window.onload does not work properly in jsfiddle, so replace
window.onload = function () {
$("sound1").onclick = sound1_click;
$("sound2").onclick = sound2_click;
}
with
$("sound1").onplay = sound1_click;
$("sound2").onplay = sound2_click;
fiddle demo
or you can simply generalize it by:
var audios = document.getElementsByTagName('audio');
for(var i=0; i<audios.length;i++) audios[i].onplay = pauseAllAudios.bind(null, audios[i]);
function pauseAllAudios(audio){
for(var i=0; i<audios.length;i++)
if(audios[i]!=audio) audios[i].pause();
};
