Window: vrdisplaydeactivate event

{{APIRef("Window")}}{{Deprecated_Header}}{{Non-standard_Header}}

The vrdisplaydeactivate event of the WebVR API is fired when a VR display can no longer be presented to, for example if an HMD has gone into standby or sleep mode due to a period of inactivity.

[!NOTE] This event was part of the old WebVR API. It has been superseded by the WebXR Device API.

This event is not cancelable and does not bubble.

  info.textContent = "Display deactivated.";

Specifications

This event was part of the old WebVR API that has been superseded by the WebXR Device API.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 Device API, 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.
