XRSessionEvent: session property

View on MDN ↗

Secure context

The read-only XRSessionEvent interface’s session property indicates which XRSession the event is about.

Value

An XRSession object indicating which WebXR session the event refers to.

Examples

In this example, the session property is used to obtain the session object to manage when an event is received.

xrSession.addEventListener("visibilitychange", (e) => {
  switch (e.session.visibilityState) {
    case "hidden":
      myEnableRendering(true);
      break;
    case "visible":
    case "visible-blurred":
      myEnableRendering(false);
      break;
  }
});

This calls a function that reacts to the session’s visibility state change.
