Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

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.

The activeVRDisplays read-only property of the Navigator interface returns an array containing every VRDisplay object that is currently presenting (VRDisplay.ispresenting is true).

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 It has been superseded by the WebXR Device API.

Syntax

var myActiveDisplays = navigator.activeVRDisplays;

Value

An array of VRDisplay objects.

Examples

function showActive() {
  var displays = navigator.activeVRDisplays;
  for(var i = 0; i < displays.length; i++) {
    console.log('Display ' + displays[i].displayId + ' is active.');
  }
}

Specifications

This property was part of the old WebVR API that has been superseded by the WebXR Device API.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