window.onvrdisplaypresentchange

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The onvrdisplaypresentchange property of the Window interface represents an event handler that will run when the presenting state of a VR display changes — i.e. goes from presenting to not presenting, or vice versa (when the vrdisplaypresentchange event fires).

The event object is of type VRDisplayEvent.

Syntax

window.onvrdisplaypresentchange = functionRef;

Examples

The presenting state of a VRDisplay can be checked using the VRDisplay.isPresenting property.

window.onvrdisplaypresentchange = function() {
  if(vrDisplay.isPresenting) {
    info.textContent = 'Display has started presenting.';
  } else {
    info.textContent = 'Display has stopped presenting.';
  }
};
