Detect orientation change in Ionic App

I've tried with events, but that doesn't work.

document.addEventListener('onorientationchange', function() 
   {...}
);

I know how to get the orientation of the screen, but i didn't find out how to detect when the orientation changes.

Solution

First you need to install the cordova-plugin-screen-orientation plugin:

For cordova < 4 run:

cordova plugin add net.yoik.cordova.plugins.screenorientation

For cordova > 4 run:

cordova plugin add cordova-plugin-screen-orientation

The plugin adds the following to the screen object (window.screen):

// lock the device orientation
.lockOrientation('portrait')

// unlock the orientation
.unlockOrientation()

// current orientation
.orientation

Now you can use something like the following to detect the orientation of the screen:

window.addEventListener("orientationchange", function(){
    console.log(screen.orientation); // e.g. portrait
});
