MDN wants to learn about developers like you:


This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The VRDisplayEvent constructor creates a VRDisplayEvent object instance.


var myEventObject = new VRDisplayEvent(type, eventInitDict);


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