Avoid multi-touch zoom on devices

[MAN]

Hey Armin,

I have noticed (not sure if since the last version) that now you can zoom using multi-touch on devices. It seems like a non-responsive behaviour. Any way to avoid it?

Thanks

Oh

Ok, I think probably this has to do with a new version of the safari ios browser. I'm using a metatag that is preventing zooming and it has always worked before.

Writing it down and will try to fix it with an update some day. I should make this an option.

Yeah, you are right. I just found it out.

In case somebody is interested, I've got this code which did the trick:

<script>
document.documentElement.addEventListener('touchstart', function (event) {
if (event.touches.length > 1) {
event.preventDefault();
}
}, false);

var lastTouchEnd = 0;
document.documentElement.addEventListener('touchend', function (event) {
var now = (new Date()).getTime();
if (now - lastTouchEnd <= 500) {
event.preventDefault();
}
lastTouchEnd = now;
}, false);
</script>

this could possibly prevent the carousel addon from being slideable on touch devices, not sure

@arminunruh I'm using Carousel and it seems to work fine. Actually that's why I wanted to achieve this, to avoid zooming when touching to navigate between slides on Carousel.
