问题
We're writing a mobile app using jQuery mobile and do most of the javascript debugging in Chrome. One thing I can't test however is an orientation change, from portrait to landscape and vice versa. I have to use a phone to fire that event, and am unable to debug the javascript window.orientationchange event without Chrome.
Or so it would seem. Is there a way to mock this event in Chrome somehow?
回答1:
Since a desktop device doesn't have any real orientation changes, like mobile devices does have, it's no use to listen to orientationchange. You could simulate orientation by resizing the browser window though.

A way to test your media queries based on orientation:
The Window Resizer extension for Google Chrome enables you to view and test your site in either portrait or landscape orientation. When installed, it has a size predefined of 320 x 480 and the orientation returned by jQuery using $.event.special.orientationchange.orientation() will be "portrait". I added a new size of 480 x 320 for landscape and indicated a "Screen Type" of mobile. In 480 x 320 size, the orientation returned by jQuery using $.event.special.orientationchange.orientation() will be "landscape".
This does not allow you to test the orientation change event specifically, but it is very useful for testing media queries based on orientation.
