Menu
I am trying to prevent the default scrolling within a web app which contains an HTML5 video element on Mobile Safari. Handling document.ontouchmove and calling e.preventDefault() has been the standard way that I've found to achieve this.
This seems to work everywhere except when you touch on top of the video element, where you can start pulling the page all around as if it is going to scroll. This only seems to happen when the native video controls are forced on. If you don't include the controls attribute and load the video in a way that it can be played in-line (such as on the iPad or in a UIWebView with allowsInlineMediaPlayback set), scrolling is prevented properly. So it seems like it has something to do with the native video controls (the big play button) capturing the event.
Here is a contrived example of what I am doing:
<!DOCTYPE HTML>
<html>
<head>
<title>HTML5 Video Example</title>
<meta name="viewport" content="width=device-width,initial-scale=1.0,user-scalable=no">
</head>
<body style="background: blue;">
<video src="http://cdn.kaltura.org/apis/html5lib/kplayer-examples/media/bbb_trailer_iphone.m4v" controls></video>
<script>
window.onload = function() {
document.ontouchmove = function(e) {
e.preventDefault();
}
}
</script>
</body>
</html>
Any ideas of workarounds to completely prohibit scrolling behavior, even on the video? I've already tried handling ontouchmove directly on the video element and it doesn't work.
Thanks!

In my test, when ommiting the "controls" attribute of the video you can get the events to work. Use a custom div in top to provide custom controls
By example....
<video src="http://192.168.1.53/videoTester/Cuatro.mp4" id="player" width="100%" height="100%" x-webkit-airplay="allow" ></video>
Like you, I couldn't prevent scrolling, so as a workaround added a JS function to fire window.scrollTo(0, 1); every second which then means the user can only scroll for a certain time before the page is jumped back.
