An end event is fired at an XRSession object when the WebXR session has ended, either because the web application has chosen to stop the session, or because the user agent terminated the session.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("end", (event) => {});

onend = (event) => {};

An XRSessionEvent. Inherits from Event.

In addition to the properties listed below, properties from the parent interface, Event, are available.

session Read only

The XRSession to which the event refers.

Triggered when the WebXR session has ended, either because the web application has chosen to stop the session, or because the user agent terminated the session.

This event is not cancelable and does not bubble.

You can use this event to react to the ending of an WebXR session. You may want to display a UI element informing about the termination of the session, for example.

To be informed when a WebXR session comes to an end, you can add a handler to your XRSession instance using addEventListener(), like this:

XRSession.addEventListener("end", (event) => {
  /* the session has shut down */
});

Alternatively, you can use the XRSession.onend event handler property to establish a handler for the end event:

XRSession.onend = (event) => {
  /* the session has shut down */
};
