window.onzoom event for tablets/ipad?

Question

Is there an event, similar to window.onorientationchange but triggered when zoom-in or zoom-out gestures were applied please? iPhone/iPad-related solutions are preferred, cross-tablet-platform solutions are warmly welcomed.

Answer 1

jQuery resize works on iOs. See http://api.jquery.com/resize/

Answer 2

There is no specific "zoom" event for multi touch I'm afraid, but you can use ongesturestart, ongesturechange and ongestureend to deal with them. In iOS using event.preventDefault method will prevent the zoom.
