making html5 video to fullscreen - javascript

I have a custome HTML5 Video player, where in the HTML Page there is a video tag and another DIV tag where i have put the controls. The Control DIV has play button,Pause button, Fullscreen button etc. Now i am trying to make the video full screen on the click of the full screen button. I have written the code making the use of requestFullscreen(). This code is not throwing any error but its neither working. Could someone please tell me where i am going wrong??
var controls = {
video: $("#player"), //this is the video element
fullscreen: $("#fullscreen") //This is the fullscreen button.
};
controls.fullscreen.click(function(){
var elem = controls.fullscreen;
if (elem.requestFullscreen) {
controls.video.requestFullscreen();
} else if (elem.mozRequestFullScreen) {
controls.video.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen) {
controls.video.webkitRequestFullscreen();
}
});

controls.fullscreen and controls.video are both jQuery objects, not DOM elements. You want the elements inside the jQuery objects, which you can get with .get:
var controls = {
video: $("#player").get(0), //this is the video element
fullscreen: $("#fullscreen").get(0) //This is the fullscreen button.
};
jQuery objects don't have a requestFullscreen property, so none of your if statement were running (and if they had run, video.requestFullscreen wold have failed).

Play .mp3 or .gif file in Google AppMaker

Is there a way we can play audio sound or Gif image on Google AppMaker? I have tried the following to play .sound that I kept as HTML containing the .mp3 file src I copied from the Resources.
var page = app.pages.RateToilet;
var x = page.descendants.sound;
function playAudio() {
x.play();
}
I got the following error
x.play is not a function
at playAudio (client:24:7)
at RateToilet.Image7.onClick:5:3
Please advise .. Thanks :)
To play a .gif file is pretty straight forward. After you've uploaded the file to the resources section of appmaker, you simply need to drag and drop as shown below.
Now, to play a sound you've saved inside the resources, please do the following:
1) Add a button widget and set its text property to "play sound".
2) Add the following code to the onClick event of the button widget:
var track = "";
var audio = document.getElementById("audio");
audio.setAttribute("src", track);
if(widget.text === "play sound") {
widget.text = "stop sound";
audio.play();
} else {
widget.text = "play sound";
audio.pause();
audio.currentTime = 0;
}
3) Add an HTML widget below the button widget.
4) Make sure to check the allowUnsafeHtml checkbox
5) Put the following inside the HTML widget html value:
<audio id="audio"></audio>
6) Next, go to the html display section and make sure to uncheck visible and set visibility type to hidden, just as shown below
7) Finally, go to the resources section of appmaker, copy the resource URL and paste its value inside the onClick event of the button widget, so that var track equals to that value. See below:

Add attribute to html tag with Javascript

I am using a Javascript code to detect if a video is loaded.
Once it is loaded I want to add an autoplay attribute to the <video> tag to make it play but I can't find a way to add that attribute. Here is the code I use:
window.addEventListener('load', function() {
var video = document.querySelector('#bgvid');
var div = document.getElementById('#bgvid');
function checkLoad() {
if (video.readyState === 4) {
alert('video is loaded')
video.setAttribute("autoplay")
} else {
setTimeout(checkLoad, 100);
}
}
checkLoad();
}, false);
******************* THE SOLUTION ********************
First, thanks DontVoteMeDown for the help.
Proper code should be:
document.getElementById('bgvid').addEventListener('canplaythrough', function() {
this.play();
});
Why not add the attribute to the tag? From the docs:
autoplay: (...) the video will automatically begin to play back as soon as it can do so without stopping to finish loading the data.
So I presume (not sure, indeed) that the video will start playing as soon it loads a part of the video.
Anyway, if you still want to add the attribute, the video tag has some Events, from docs:
canplay: Sent when enough data is available that the media can be played, at least for a couple of frames;
canplaythrough: Sent when the ready state changes to CAN_PLAY_THROUGH, indicating that the entire media can be played without interruption(...);
So you can use one of those events to set the attribute, e.g:
document.getElementById('bgvid').addEventListener('canplay', function() {
this.setAttribute("autoplay", "autoplay");
});
With this you can avoid using timeouts, which isn't the best approach.
with autoplay enabled there is no need to check its load state, the video will simply play when it can, is loaded.
video.autoplay = true;

jQuery - FadeToggle - different actions if element is visible or not

I have a button, when you click on that button, I'm doing a fadeToggle() to show or hide a popup.
That popup is appearing on top of a flash video that autoplays.
So, what I want to do, is when the popup is visible, I want to pause the video. When it's hidden, play the video.
My video player already support those function. So this is working fine:
videoPlayer.pause();
videoPlayer.play()
So what my FadeToggle() would looks like ? Right now I have this code:
$("#categorySlider").fadeToggle('fast', function() {
var videoPlayer = document.getElementById("videoContainer");
videoPlayer.pause();
});
I'm missing the play() part here, but I cant figure out the syntax to add it?! If fadeToggle is not the right thing to use, any jquery or javascript is fine!
Any helps please?
You could use the jquery :visible selector to find out if #categorySlider is visible or not and depending on that pause or play the video.
$("#categorySlider").fadeToggle('fast', function() {
var videoPlayer = document.getElementById("videoContainer");
if ($("#categorySlider").is(":visible"))
videoPlayer.pause();
else
videoPlayer.play();
});

HTML5 Video Not Pausing

I am working on a iPad HTML app that has two videos in it. The HTML code is loaded dynamically. The page has two videos with text corresponding to them. The videos also have just two controls. Play and Pause. However the issue I am having is the Video will only pause when the other is playing. Basically in my if / else statement the else is not being called at all. Here is my code. Anyone know why it won't pause when trying to click on the overlay again? Thank you in advance!
$('div[class*="video-overlay"]').bind('mousedown', function() {
var video = $(this).next('video')[0];
var text = $(this).attr('data-play');
if (video.paused) {
video.play();
$('p').addClass('fade');
$('#' + text).removeClass('fade');
$(this).removeClass('overlay');
$('div[class*="video-overlay"]').not(this).addClass('overlay');
$(this).children().removeClass('video-play');
$('video').not($(this).next(el)).get(0).pause();
$('.play').not($(this).children()).addClass('video-play');
$(video).on('ended', function() {
$(this).prev('div').children().addClass('video-play');
video.pause();
});
} else {
video.pause();
console.log('Hey mom, I paused all by myself!');
}
});
Without your html, I can't be sure, so I can only guess.
var video = $(this).next('video')[0];
change this line to
var video = $(this).find('video')[0];
To get a more definite answer, please provide your html code.
It was actually in my CSS. I didn't have the overlay in front of the video. So I changed the z-index to a higher value and the fixed it. I had the play button in front so it was playing the video, just not the overlay. Doh!

Using jQuery to control HTML5 <audio> element

I'm trying to use jQuery to control an HTML5 audio element, but I'm no genius with JS.
What I want is for the player to start on page load, which I've done, but when the play button is clicked, I want to check whether or not the audio is playing.
If it's playing when clicked: Stop the audio.
If it's not playing when clicked: Play the audio.
If you could help, it'd be much appreciated.

Many thanks,
you should use a single play/pause toggle button in which you need to check if your audio is paused or not
var audioplayer = document.getElementById("audio-player");
$("#play-bt").click(function(){
if (audioplayer.paused) {
audioplayer.play();
}
else {
audioplayer.pause();
}
$(this).toggleClass('pause'); /* style your toggle button according to
the current state */
})
var audio = new Audio("http://www.w3schools.com/html5/song.ogg"); //or you can get it with getelementbyid
audio.addEventListener('canplay', function() {
//code, when audio can play
audio.play(); //this function will start the music
})
with audio.play() function you can start it. You don't need JQuery
If you wish to use a jquery selector or have a jquery selector already, you can add [0] to get the native dom element.
So an example that actually uses jquery would be.
$('audio')[0].pause()
