Detect mobile device rotation with jQuery

问题

I am searching for a jQuery-plugin or Javascript-library that detects the rotation of a device in degrees, not just orientation, using the G-sensor. I know it can be done - check http://wagerfield.github.io/parallax/ - but I haven't managed to find something like this yet.

It would be great if it created a kind of global that updates realtime.

Thanks!

you can use jquery mobile lib orientationchange event.

$(window).on("orientationchange",function(event){
    var x = event.beta,  // -180 to 180
        y = event.gamma, // -90 to 90
        z = event.alpha; // 0 to 360
});

without jQuery:

window.addEventListener('orientationchange', function(event){
    var x = event.beta,  // -180 to 180
        y = event.gamma, // -90 to 90
        z = event.alpha; // 0 to 360
});

also try this..

if (window.DeviceOrientationEvent) {
    window.addEventListener('deviceorientation', function(event){
    });
}
