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();
};
