I try to use html5 video from below website
http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_video_js_prop
How can i play/pause video on video screen click ?
Any help will be appreciated.
Thanks.
Simply you can call the function video on click
<video id="video1" onClick="playPause();">
...
</video>
The shortest way
onclick="this[this.paused ? 'play' : 'pause']()"
The right (but still short) way
...considering you already have your video in variable,you should generally use event listeners and not hard coded onX attributes...(even if you have callback!)
var myVideo = document.getElementById("video1");
myVideo.addEventListener('click', function(e){
e.preventDefault();
this[this.paused ? 'play' : 'pause']();
});
PS: If you are wondering how the hack does the play/pause line work - it is based on the fact that in JavaScript, methods/object functions are basically callable properties of that object and also that in JavaScript, you can reference property directly someObj.someProperty but also through value or variable like someObj["someProperty"] , var prop = "someProperty"; someObj[prop];
... so a long equivalent of the one-liner would be
if (this.paused) {
this.play();
} else {
this.pause();
}

I am displaying a video on my website like this:
<video>
<source src={link} type="video/mp4" />
</video>
And I would like to extract duration of the video from the provided src link, to display it somewhere else on the page. Assume we have the link stored as a string, how will I extract the duration of the video?
Sample src link: https://firebasestorage.googleapis.com/v0/b/qriositynet-dev.appspot.com/o/chat%2FMgttfKqKIDhQ6bgtgy6V%2Fvideos%2F1663229371400watermelon-bunny.mp4?alt=media&token=722bb260-c65b-46fe-8805-4a5a742f282d
to get the duration of the video you have to wait for it to load using the event listener and that way you are sure you have the data, this is a link you can use to help you learn more about the API, here.
let video = document.getElementById("video")
video.addEventListener('loadeddata', function() {
console.log("test", video.duration)
// Video is loaded and can be played
}, false);
function myFunction() {
alert(video.duration);
}
myFunction
<html>
<h1>video duration</h1>
<button onclick="myFunction()" type="button">Get video length</button><br>
<video id="video">
<source src="https://firebasestorage.googleapis.com/v0/b/qriositynet-dev.appspot.com/o/chat%2FMgttfKqKIDhQ6bgtgy6V%2Fvideos%2F1663229371400watermelon-bunny.mp4?alt=media&token=722bb260-c65b-46fe-8805-4a5a742f282d" type="video/mp4" />
</video></html>
The video tag has a "duration" property, which will tell you the length of a video.

Is it possible to set a video to full screen on page load?
So far, the only answer I could get to work and was actually logical to me was setting the width and height on the element via CSS.
var $pop = Popcorn("#video");
$pop.play();
console.dir( $pop )
html{font-family:arial;}
#video{width:100%;height:100%;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://popcornjs.org/code/dist/popcorn-complete.min.js"></script>
<video height="180" width="300" id="video" controls>
<source src="http://videos.mozilla.org/serv/webmademovies/popcornplug.mp4"></source>
<source src="http://videos.mozilla.org/serv/webmademovies/popcornplug.ogv"></source>
<source src="http://videos.mozilla.org/serv/webmademovies/popcornplug.webm"></source>
</video>
I use Popcorn.js for playing the video on startup.
I am aware of setting CSS classes from JavaScript. The thing I'm more interested in would be the question: is there is a JavaScript based method to call, to maximize the video to full screen (on startup).
Using JavaScript, as suggested by Will, I also can't seem to get it to work properly
var video = $("#video");
var vid = video[0];
vid.play();
if (vid.requestFullscreen) {
vid.requestFullscreen();
} else if (vid.mozRequestFullScreen) {
vid.mozRequestFullScreen();
} else if (vid.webkitRequestFullscreen) {
vid.webkitRequestFullscreen();
}
html{font-family:arial;}

I made a website (not on air yet) and I tested it live with some free hosting.
The website contains a map tag and a big picture within it.
I made it so if someone clicks on a part of the picture a specific audio will be heard, according to where he clicked.
My problem is that there are a lot of audio tags (about 300) and because there are lots of bandwidth-hogging files, it takes about 10 minutes until the website is fully loaded which means most of the audios don't work for several minutes.
I want to know if there is a way, maybe a responsive way with javascript or PHP that will allow me to make those audio tags only if the user clicks on the map. That way it will not use that much bandwidth. Also if anyone can think of a better way it will greatly appreciated.
I'm adding the javascript for the click event so you can see what it is all about -
$('#Swensens_maze').click(function(){
$('audio').each(function(){
this.pause(); // Stop playing
// Reset time
});
$('#Swensens_maze_audio').get(0).play();
return false;
});
This is one example from many. The "#swensens_maze" is the area tag and the "#Swensens_maze_audio" is the audio tag for it.
Your problem happens because browser tries to preload the audio for each audio tag.
So the answer is to set the attribute preload in the audio tag to value none
<audio preload="none">
EDIT The audio now automatically strats
EDIT 2 I have just remembered that an empty src is a bad practice, I will find a solution, the best one is to store the information in some other tag and then create a the audio tag with js
EDIT 3
JS FIDDLE VERSION 2
Better version,doesn't leave an empty src attribute, all the audio information are stored inside the the hidden input, once you click the area the audio tag is provided through JS inside the clicked div.

return;
var childInput = $(this).find('input:hidden'), //Find information
audioTag = document.createElement("AUDIO"),// Create AUDIO element
audioSource = document.createElement("SOURCE"), //Create SOURCE element
audioType = childInput.attr('data-format'),//retrieve audio type, then you could checkif the browser supports this format
audioSrc = childInput.attr('data-original'); //retrieve audio src
//Set type and src of the source
audioSource.type= audioType;
audioSource.src= audioSrc;
//Enable controls and append SOURCE to AUDIO
audioTag.controls = true;
audioTag.appendChild(audioSource);
this.appendChild(audioTag);// Append the created audio tag to the clicked div
audioTag.load();//Load the src
audioTag.play();//Play the audio
return false;

OLDER ANSWER
Bad for empty src
$('div.map').click(function () {
$('audio').each(function () {
this.pause();
});
var audioTag = $(this).find('audio'),
sourceTag=audioTag.children('source');
if (sourceTag.attr('src')=='') {
sourceTag.attr('src', sourceTag.attr('data-original'));
audioTag.load()
}
audioTag.get(0).play();
return false;
});

Yes don't leave the src attribute empty, but give to src a valid blank and short file.mp3.
Then when user click or whatever replace the src by the good file, like this:
document.getElementById("audio8").src = "song.mp3";
Also, depending of how is made your page, if audio's appear block after block, have a look to lazysize.js for smoothly load your content when scroolling. Easy to use and powerful.

Your browser tries to preload the audio for each audio tag. So the answer is to set the attribute preload in the audio tag to value none
use can use: <audio controls preload="none">
I have tried to create a function in javascript to mute a html video, and change the icon below to a mute icon that i have downloaded. Need Help. The javascript has to be able to work along side jquery as well
demo - http://jsfiddle.net/victor_007/6cc9mhbb/
on click of the button the icon will change
$("video").prop('muted', true);
$(".mute-video").click(function () {
if ($("video").prop('muted')) {
$("video").prop('muted', false);
$(this).addClass('unmute-video'); // changing icon for button
} else {
$("video").prop('muted', true);
$(this).removeClass('unmute-video'); // changing icon for button
}
console.log($("video").prop('muted'))
});
The question is fairly vague, so I'm guessing that this will answer your question.
If you are using video tags in HTML
<video width="320" height="240" controls muted>
<source src="x" type="video/x">
<source src="x" type="x">
</video>
For Java script
<video id="myVideo" width="x" height="x" controls>
....
</video>
<button onclick="enableMute()" type="button">Mute sound</button>
<script>
var vid = document.getElementById("myVideo");
function enableMute() {
vid.muted = true;
}
</script>
As for your second questions, I don't quite understand it, please elaborate.
I'm using html5 video player to play some videos and trying to use external controls with javascript. manage to get the player play and pause. but i cannot get it to mute and unmute using the buttons. if someone can help with this matter its highly appropriated.
Here is the HTML code
<video id="myMovie" width="600" height="600" loop preload="auto" video poster="img.jpg" controls>
<source src="my-video-file.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<button id="playButton">Play</button>
<button id="volButton">Mute</button>
JavaScript Code
function playMymovie() {
var element = document.getElementById('myMovie');
var element = document.getElementById('pbutton');
playButton.addEventListener('click', PlayOrPause, false);
volButton.addEventListener('click', VolMute, false);
}
function PlayOrPause() {
if(!myMovie.paused && !myMovie.ended) {
myMovie.pause();
}else{
myMovie.play()
}
}
function VolMute(){
if(!myMovie.muted){
myMovie.muted(true);
}else{
myMovie.muted(false);
}
}
Thanks in advance.
