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. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The VRDisplayEvent() constructor creates a VRDisplayEvent object.
Note: This constructor was part of the old WebVR API. It has been superseded by the WebXR Device API.
Syntaxnew VRDisplayEvent(type, options)
type
A string with the name of the event. It is case-sensitive and browsers set it to vrdisplayconnect, vrdisplaydisconnect, vrdisplayactivate, vrdisplaydeactivate, vrdisplayblur, vrdisplaypointerrestricted, vrdisplaypointerunrestricted, or vrdisplaypresentchange.
options
An object that, in addition of the properties defined in Event(), can have the following properties:
display
The VRDisplay the event is to be associated with.
reason
A string representing the human-readable reason why the event is to be fired (see VRDisplayEvent.reason).
A new VRDisplayEvent object.
const 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This constructor was part of the old WebVR API that has been superseded by the WebXR Device API.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. Read Meta's Porting from WebVR to WebXR guide for more information.
