Window: vrdisplaypresentchange event

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 vrdisplaypresentchange event of the WebVR API is fired when the presenting state of a VR display changes — i.e. goes from presenting to not presenting, or vice versa.

Examples

You can use the vrdisplaypresentchange event in an addEventListener method:

window.addEventListener('vrdisplaypresentchange', function() {
  if(vrDisplay.isPresenting) {
    info.textContent = 'Display has started presenting.';
  } else {
    info.textContent = 'Display has stopped presenting.';
  }
  reportDisplays();
});

Or use the onvrdisplaypresentchange event handler property:

window.onvrdisplaypresentchange = function() {
  if(vrDisplay.isPresenting) {
    info.textContent = 'Display has started presenting.';
  } else {
    info.textContent = 'Display has stopped presenting.';
  }
  reportDisplays();
};
