This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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.
| Bubbles | No |
| Cancelable | No |
| Target objects | Window |
| Interface | VRDisplayEvent |
Examples
window.addEventListener('vrdisplaypresentchange', function() {
if(vrDisplay.isPresenting) {
info.textContent = 'Display has started presenting.';
} else {
info.textContent = 'Display has stopped presenting.';
}
reportDisplays();
});
Inheritance
The vrdisplaypresentchange event implements the VRDisplayEvent interface, which inherits from Event — its event object therefore has available the properties and methods defined on both these interfaces.
