javascript detect if browser/device supports screen rotation

Question

Is there a way to detect if the browser/device supports screen rotation, without having to wait for the orientationchange event? I'm not trying to detect the rotation itself, only if the browser or device supports it.

Answer 1

I think you can detect it like so:

if( 'onorientationchange' in window) { /* supported! */ }

However, I'm not sure if some browsers will support the event even though they never fire it.
