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.';
  }
};
