Click function to play video not working on tablet - javascript

I have the below click function so that when a video is clicked the video plays. It works perfectly on desktop browsers, but on tablets does not. You press it and the video instantly pauses. I believe this is to do with the click function looking for a click and there not being one on a tablet but I'm unsure how to solve it.
HTML
<div class="section">
<div class="video">
<video poster="img/my-poster.jpg"><source src="mp4/low-res/my-video.mp4" type="video/mp4"></video>
</div>
</div>
jQuery
$(document).ready(function () {
$('.section video').on("click touchstart", function() {
this.paused ? this.play() : this.pause();
});
});

That's because your touchstart and click are in conflict.
There is a hack to prevent this conflict :
var flag = false;
$('.section video').on("click touchstart", function(){
if (!flag) {
flag = true;
setTimeout(function(){ flag = false; }, 100);
this.paused ? this.play() : this.pause();
}
return false;
});

click event for for video tag except when control clicked

I have a element where I would like to toggle the default controls when clicking the element, but when the controls are shown using these controls shouldn't toggle control visibility.
I'm adding the handler as bubbling, hoping that the built-in controls would preventDefault such that my handler was never invoked but the event caller is always called at least on Safari.
var video = document.getElementById("video");
video.addEventListener('click', function(evt) {
video.controls = !video.controls
});
Is there some other way to add the event handler or perhaps properties on the event I can use to differentiate clicks on the video controls vs. clicks other places in the video element?
"Is there some other way to add the event handler or perhaps properties on the event I can use to differentiate clicks on the video controls vs. clicks other places in the video element?"
No Apple devices here to test on Safari but, in Chrome the clicking of a UI button (like "Play" or "Fullscreen") does not count as a click on the <video> element itself.
You can differentiate by knowing that if the element (picture part, not buttons) is clicked then it returns as: [object HTMLVideoElement]
In your code you can test as:
vid.addEventListener('click', function(evt) {
alert("click target is : " + evt.target);
vid.controls = !vid.controls
});
As a quick side-note, you can see how there is also an opportunity to create one "master" click function, like document.addEventListener('click' ... where you check the evt.target or even the evt.target.id and use If/Else to control anything clicked on the page from just one function. Example:
if (evt.target.id == "myVid") { ...do_someThing(); }
Finally, see if the code below is doing what you want to actually achieve...
You can preview the code at this W3Schools page :
<html>
<body>
<h1>Video UI : click test</h1>
<video id="myVid" width="320" height="240" loop controls>
<source src="movie.mp4" type="video/mp4">
</video>
<script>
var isPlaying = false;
var vid = document.getElementById("myVid");
vid.addEventListener("click", onclick );
function onclick(evt)
{
evt.preventDefault();
if ( vid.paused == true) { isPlaying = false; }
else{ isPlaying = true; }
if( evt.target.nodeName == "VIDEO") { vid.controls = !vid.controls; }
if ( isPlaying == true) { vid.play(); }
}
</script>
</body>
</html>

How to disable html5 audio element play/pause button

What is the way to disable or prevent events from the play/pause button in the html5 audio element?
I am trying something like this:
document.getElementById(id).addEventListener("pause", function() {
$(this).trigger("play");
});
This works when alone, but my problem is that I would like to control the play/pause when clicking on the div where the audio element is in:
<div id="my_div">
<audio controls id="my_audio">
<source src="my_song.mp3" type="audio/mpeg">
</audio>
</div>
var is_playing;
$("#my_div").click(function () {
if (is_playing) {
$('#my_audio').trigger("pause");
is_playing = false;
} else {
$('#my_audio').trigger("play");
is_playing = true;
}
});
so this causes conflict when I use the pause/play buttons of the audio element. So, I am searching a way to prevent the event of the play/pause audio element control (but not the whole controls as I need to use the seekbar and volume).
play and pause are not jQuery methods. Try calling .play(), .pause() on <audio> element
$(function() {
var is_playing;
$("#my_div").click(function(e) {
// if `e.target` is not `<audio>` element
if(e.target.tagName !== "AUDIO") {
if (is_playing) {
$('#my_audio')[0].pause();
is_playing = false;
} else {
$('#my_audio')[0].play();
is_playing = true;
}
} else {
e.stopPropagtion()
}
});
});

CSS scrolling issue in mobile phone

I have been trying to solve this weird problem with scrolling in my website. The scrolling works fine when viewed on a Desktop Computer. However, it doesn't work in mobile phones. Do, I need to use some javascript to solve this issue?Or, can it be done just with CSS.
Here is my CSS snippet :
#popup-div{
height: 100%;
overflow:scroll;
}
function isTouchDevice(){
try{
document.createEvent("TouchEvent");
return true;
}catch(e){
return false;
}
}
function touchScroll(id){
if(isTouchDevice()){ //if touch events exist...
var el=document.getElementById(id);
var scrollStartPos=0;
document.getElementById(id).addEventListener("touchstart", function(event) {
scrollStartPos=this.scrollTop+event.touches[0].pageY;
event.preventDefault();
},false);
document.getElementById(id).addEventListener("touchmove", function(event) {
this.scrollTop=scrollStartPos-event.touches[0].pageY;
event.preventDefault();
},false);
}
}
//On page load
touchScroll('popup-div');

Closing modal with e.keypress

I have the following modal box:
<div class="modal-video" id="v-5417">
<div class="video-player">
<video id="v-5417-tape" preload="none">
<source type="video/mp4" src="videos/anthem-od47.mp4">
<source type="video/webm" src="videos/anthem-od47.webm">
</video>
<div class="close-modal fade-control"></div>
</div>
</div>
and trying to use the following e.keyCode to close the modal:
$(document).keydown(function (e) {
if (e.keyCode == 27) {
$(".modal-video").hide();
}
});
This is only hiding the video, but not closing the modal and killing the video. How can I completely close the modal and video together?
jQuery .hide() just changes the CSS style to display:none, so your video is hided and still playing in the background. To fix that issue, you can stop playing the video by standard HTML5 pause() method.
If hiding $(".modal-video") doesn't work for you, then I assume you need to hide it's parent - but we have to see more your code to be sure about that.
$(document).keydown(function (e) {
if (e.keyCode == 27) {
var video = document.getElementById("v-5417-tape");
video.pause()
$(".modal-video").parent().hide();
}
});
If you are using some kind of player template or plugin, and click on class "close-modal" hides the modal as you expect - then you can use jQuery .toggle() method to call click event on that element, when you press your key.
$(document).keydown(function (e) {
if (e.keyCode == 27) {
var video = document.getElementById("v-5417-tape");
video.pause()
$(".close-modal").toggle("click")
}
});
The active state has to be removed, and that disabled the popup.
$(document).keydown(function (e) {
var video = document.getElementById("v-5417-tape");
if (e.keyCode == 27) {
if(video.play){
video.pause();
}
$(".modal-video").removeClass("active");
}
});

Using input in textarea to trigger a video event - javascript

I'm working on an HTML5 video logging and transcription application. The transcriptionist needs to be able to start and stop the video using a keyboard shortcut / accelerator rather than clicking a button. Is there a way for me to use javascript to do this without leaving the textarea box?
Thanks,
Norm
Try this JSFiddle. Shortcut for stopping/starting the video is 'alt + enter key'.
HTML:
<video src="http://v2v.cc/~j/theora_testsuite/320x240.ogg" controls id="video">
Your browser does not support the <code>video</code> element.
</video>
<textarea></textarea>
Javascript (using jQuery):
$(function(e) {
$('textarea').keydown(function(e) {
// shortcut for stopping/starting the video
// is alt + enter
if (e.altKey && e.keyCode == 13) {
toggleVideoPlay();
return false;
}
});
});
function toggleVideoPlay() {
var video = $('#video')[0];
if (video.paused) {
video.play();
} else {
video.pause()
}
}​
