How did YouTube make videos autoplay in iPad and iPhone?

Question

iOS

Good afternoon! The subject itself, or how it can be done in the video tag

Answer 1

Fake click trick worked on ancient versions of iOS

        function fakeClick(fn) {
            var $a = $('<a href="#" id="fakeClick"></a>');
                $a.bind("click", function(e) {
                    e.preventDefault();
                    fn();
                });

            $("body").append($a);

            var evt, 
                el = $("#fakeClick").get(0);

            if (document.createEvent) {
                evt = document.createEvent("MouseEvents");
                if (evt.initMouseEvent) {
                    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
                    el.dispatchEvent(evt);
                }
            }

            $(el).remove();
        }

        $(function() {
            var video = $("#someVideo").get(0);

            fakeClick(function() {
                video.play();
            });
        });

But as far as I understand, at least with iOS 6.x, this no longer works.
On YouTube, things are a little trickier. When you open youtube.com, you see a list of videos and click on one. At this point, there is actually no transition to another page (navigation happens through a hash in the URL). Since we stayed on the same page, we can bind the start of playback to a click, most likely something similar to the example from the documentation is used:

 <input type="button" value="Play" onclick="document.myMovie.play()">

For the sake of interest, enter a direct url to some video in the browser on the iPad and do not click on the page. Will auto play start?

www.w3schools.com/tags/att_video_autoplay.asp - is it?

Answer 3

Is it autoplay?
In my opinion, one click is required. And in the context of the click handler, you can start playing the video.

Answer 4

I just did video.play(); and it works, but there the call was in the execution context after changing the slide on the screen, maybe this somehow affected the work.

Answer 5

doing like this

<script>
myVid=document.getElementById("video1");
myVid.play();
</script> 

on the

Mozilla/5.0 (iPad; U; CPU OS 6_1 like Mac OS X; ja-jp) AppleWebKit/536.26 (KHTML, like Gecko) Version/6 Mobile/10B141 Safari/8536.25

does not play ... as I understand it, you even have a newer version

Answer 6

And look at the js from this site here is a
link to the first movie that came across.
On my second pad with iOS 6.1, the video automatically plays (by the way, it's sooooo annoying)
