orientationchangeend

NPM version Bower version

The orientationchangeend event is fired when the orientation of the device has changed and the associated rotation animation has been complete. orientationchangeend enables you to capture dimensions of the element in the state after the rotation change.

The Underlying Implementation

There is no way to capture the end of the orientation change event because handling of the orientation change varies from browser to browser. Drawing a balance between the most reliable and the fastest way to detect the end of orientation change requires racing interval and timeout.

A listener is attached to the orientationchange. Invoking the listener starts an interval. The interval is tracking the state of window.innerWidth and window.innerHeight. The orientationchangeend event is fired when config.noChangeCountToEnd number of consequent iterations do not detect a value mutation or after config.noEndTimeout milliseconds, whichever happens first.

If there is a series of orientationchange events fired one after another, where n event orientationchangeend event has not been fired before the n+2 orientationchange, then orientationchangeend will fire only for the last orientationchange event in the series.

Usage

var config = {},
    OCE;
 
// Start tracking the orientation change.
OCE = gajus.orientationchangeend(config);
 
// Attach event listener to the "orientationchangeend" event.
OCE.on('orientationchangeend', function () {
    // The orientation have changed.
});

To make the orientationchangeend event available to the window, re-emit the event using a custom event:

var orientationchangeend;
 
// Make sure that you are not adding event emitter more than once.
if ('onorientationchangeend' in window) {
    window.onorientationchangeend = true;
 
    orientationchangeend = new CustomEvent('orientationchangeend');
 
    OCE.on('orientationchangeend', function () {
        window.dispatchEvent(orientationchangeend);
    })
}
 
// Attach a listener to the "orientationchangeend" event.
window.addEventListener('orientationchangeend', function () {
    console.log('The orientation of the device is now ' + window.orientation);
});

Configuration

Name Value Default
noChangeCountToEnd Number of iterations the subject of interval inspection must not mutate to fire orientationchangeend. 100
noEndTimeout Number of milliseconds after which fire the orientationchangeend if interval inspection did not do it before. 1000
debug Enables logging of the events false

All of the configuration parameters are optional.
