Window: vrdisplayactivate event - Web APIs 编辑

The vrdisplayactivate event of the WebVR API is fired when a VR display is able to be presented to, for example if an HMD has been moved to bring it out of standby, or woken up by being put on.

Examples

You can use the vrdisplayactivate event in an addEventListener method:

window.addEventListener('vrdisplayactivate', function() {
  info.textContent = 'Display activated.';
  reportDisplays();
});

Or use the onvrdisplayactivate event handler property:

window.onvrdisplayactivate = function() {
  info.textContent = 'Display activated.';
  reportDisplays();
};
