I'm having difficulty calling a JavaScript function to play a video using a button element. My function script is as follows:
<button onclick = "PlayVid()">Play</button>
<button onclick = "PauseVid()">Pause</button>
<button onclick = "MaxScreen()">Full Screen</button>
<button onclick = "NorScreen()">Normal Size</button>
<div class = "video">
<video>
<source src="YellowEyePenguinVid.mp4" type="video/mp4">
</video>
</div>
<script>
var Video = document.getElementById("YellowEyePenguinVid");
function PlayVid()
{
vid.play();
}
function PauseVid()
{
vid.pause();
}
function MaxScreen()
{
Video.width = 560;
}
function NorScreen()
{
Video.width = 260; <!-- Brings video back to original size -->
}
</script>
I have declared the function that each button should call from but they are unresponsive. I've also tried quoting the name of the video inside the brackets but that doesn't work either. Could someone point out where i'm going wrong? This is the layout for other JS I have on my site and function is called successfully.
Thanks
Try this snippet. I think some parts of the player is missing, and that is why play() , pause(), and width() is not defined.
Solution
Replace
vid.play(); and vid.pause();
with
Video.play(); and Video.pause();
Since you have invoked variable as Video, not vid.
var Video = document.getElementById("YellowEyePenguinVid");
function PlayVid() {
Video.play();
}
function PauseVid() {
Video.pause();
}
function MaxScreen() {
Video.width = 560;
}
function NorScreen() {
Video.width = 260; // Brings video back to original size
}
<button onclick="PlayVid()">Play</button>
<button onclick="PauseVid()">Pause</button>
<button onclick="MaxScreen()">Full Screen</button>
<button onclick="NorScreen()">Normal Size</button>
<div class="video">
<video>
<source src="YellowEyePenguinVid.mp4" type="video/mp4">
</video>
</div>
shouldn't these:
function PlayVid()
{
Video.play(); //instead of vid.play()
}
function PauseVid()
{
Video.pause(); //instead of vid.pause()
}
if you have error message in the console paste it here, if this would solve your problem you might had a log like :
can't read property play of undefined
Replace your function with this
function PlayVid()
{
Video.play();
}
Maybe you do not have a link to scripts
you hava two option :
1.
write scripte on the page after titel
2.
write on javascript fille and put a link
under the titel
tip :
do alert on the function to see if its work!
few things need to look over,
you didn't give the id attribute to video tag.
you created an instance as Video with "V" capital but, in reality, you are using video as small case
try below code out,
<!DOCTYPE html>
<html>
<body>
<button onclick="PlayVid()">Play</button>
<button onclick="PauseVid()">Pause</button>
<button onclick="MaxScreen()">Full Screen</button>
<button onclick="NorScreen()">Normal Size</button>
<div class="video">
<video id="myVideo" width="320" height="176">
<source src="https://www.w3schools.com/tags/movie.ogg" type="video/mp4"> Your browser does not support HTML5 video.
</video>
</div>
<script>
var vid = document.getElementById("myVideo");
function PlayVid() {
vid.play();
}
function PauseVid() {
vid.pause();
}
function MaxScreen() {
vid.width = 560;
}
function NorScreen() {
vid.width = 260; <!-- Brings video back to original size -->
}
</script>

I have used a live video source for the sake of visual testing. you could replace the source as per your wish

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>
I have 4 buttons in a page. Each button is having 4 video paths but the video tag keeps playing the first path I have given to it for all 4 buttons. This is how I tried solving it:
function PlayRecordedWordSoundFile(x)
{
debugger;
var video = document.getElementById('vidplayer');
var sel=x;
video.pause();
video.removeAttribute('src'); // empty source
video.load();
var source=document.createElement('source');
source.setAttribute('src',"/x/"+sel);
video.appendChild(source);
video.play();
}
<button type="button" id="Listen" title="Listen" class="normal-but btnlistenB" value="Listen" data-id='<%# Eval("videoFilePath") %>'>Listen</button>
<video id="vidplayer"></video>
$(document).on('click','.btnlistenB',function(){
PlayRecordedWordSoundFile($(this).attr('data-id'));
return false;
});
Each button should be playing its own defined path. I have shown only one button demo since all of them are identical. Can anybody tell me what I have been doing wrong here?
First make sure you are not using the same id for all the buttons. Also since you haven't added the button click listener, I'm just using an onclick listener on the button here.
Check this working codepen here.
<video id="vidplayer" width="670" height="377" autoplay="true" controls="controls">
<source id="vidsrc"
src="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
type='video/mp4'>
</video>
<button type="button" id="Listen" title="Listen" class="normal-but btnlistenB"
data-id='http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4'
onclick="PlayRecordedWordSoundFile(this.getAttribute('data-id'));">
Listen
</button>
And then,
function PlayRecordedWordSoundFile(x) {
var video = document.getElementById("vidplayer");
var source = document.getElementById("vidsrc");
var sel = x;
video.pause();
source.removeAttribute("src"); // empty source
video.load();
source.setAttribute("src", "" + sel);
video.play();
}
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();
mates!
I was needed a simple text button – "Play". It should be hidden if video is playing and should be visible when video ends. Everything works fine, but it works only if I have one video on the page with unique ID.
HTML:
<video id="main-video" width="640" height="480">
<source src="media//mp4/video.mp4" type="video/mp4">
</video>
<span id="custom-play-button">Play</span>
And here is the JS:
window.onload = function() {
var video = document.getElementById("main-video");
var playButton = document.getElementById("custom-play-button");
playButton.addEventListener("click", function() {
document.getElementById('main-video').addEventListener('ended',myHandler,false);
video.play();
playButton.style.visibility = "hidden";
function myHandler(e) {
playButton.style.visibility = "visible";
}
});
}
But what should I do if there will be 4,5,6...100 videos on the page (and there will be)? I can't handle with 100 unique ID...
You can put every video and button in a parent div tag as below.
<div class="video-container">
<video id="main-video" width="640" height="480">
<source src="media//mp4/video.mp4" type="video/mp4">
</video>
<span id="custom-play-button">Play</span>
</div>
I'm using jQuery code, you can translate it to plain JS easily.
This should work.
$(".video-container").each(function () {
var video = $(this).find("video");
var plainVideo = video.get(0);/*DOM video object, unwrapped from jQuery*/
var playBtn = $(this).find("span");
playBtn.click(function () {
video.get(0).addEventListener('ended',myHandler,false);
plainVideo.play();
playBtn.css("visibility", "hidden");
function myHandler(e) {
playBtn.css("visibility", "visible");
}
});
});
At least this will give you an idea about the approach to this problem.
With pure Javascript (No jQuery)
You should but depend on the id, use the tag for reference, and get the nearest span. See the below code.
function closest(el, sel) {
if (el != null) return el.matches(sel) ? el : (el.querySelector(sel) || closest(el.parentNode, sel));
}
var videos = document.getElementsByTagName("video");
for (i = 0; i < videos.length; i++) {
var video = videos[i];
var playButton = closest(video, "span");
playButton.addEventListener("click", function () {
document.getElementById('main-video').addEventListener('ended', myHandler, false);
video.play();
playButton.style.visibility = "hidden";
function myHandler(e) {
playButton.style.visibility = "visible";
}
});
}
<video width="640" height="480">
<source src="media//mp4/video1.mp4" type="video/mp4">
</video>
<span class="custom-play-button">Play</span>
<video width="640" height="480">
<source src="media//mp4/video2.mp4" type="video/mp4">
</video>
<span class="custom-play-button">Play</span>
You've got to use CSS classes rather that id's and you have to use JavaScript to listen for video events and have your custom controls such as playpause button toggle. JavaScript's event.target tells you which video is doing what. MDN has a great article Creating a cross-browser video player which includes detailed instructions for custom controls for a single video.
Automated
I spent a few days creating a JavaScript that automates custom controls (Google's Material Design UI) for any number of videos on your HTML page.
The readable source code is on github at rhroyston/material-controls-for-html-video.
Fairly complex to do, but as you can see, it can be done. Live working demo is at https://hightechtele.com/articles/material-controls-for-html-video
Finally, like I said, this took me a few days. It's easy to do by hand for a single video but wanted to automate/script it. ...So view the script (and small accompanied CSS) to see how it can be done.
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();
};
