From Get docs

This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.


The isPresenting read-only property of the VRDisplay interface returns a Boolean indicating whether the VRDisplay is currently having content presented through it.

Syntax

var isItPresenting = vrDisplayInstance.isPresenting;

Value

A Boolean; true means the display is presenting; false means it isn't.

Examples

function onVRExitPresent () {
  // No sense in exiting presentation if we're not actually presenting.
  // (This may happen if we get an event like vrdisplaydeactivate when
  // we weren't presenting.)
  if (!vrDisplay.isPresenting)
    return;
  vrDisplay.exitPresent().then(function () {
    // Nothing to do because we're handling things in onVRPresentChange.
  }, function (err) {
    var errMsg = "exitPresent failed.";
    if (err && err.message) {
      errMsg += "<br/>" + err.message
    }
    VRSamplesUtil.addError(errMsg, 2000);
  });
}
