Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes.

The VRDisplayEvent() constructor creates a VRDisplayEvent object instance.

Note: This constructor was part of the old WebVR API. It has been superseded by the WebXR Device API.


var myEventObject = new VRDisplayEvent(type, eventInitDict);



A DOMString describing the type of event object you want to create.


A object containing initialization options to use when creating the constructor. These are:


A property containing the VRDisplay the event is to be associated with.


A property containing a string representing the human-readable reason why the event is to be fired (see VRDisplayEvent.reason).


var myEventObject = new VRDisplayEvent('custom', {
  display: vrDisplay,
  reason: 'Custom reason'


This constructor was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.

Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
