ON_SESSION_SWITCH event (app profile manager)

This event is invoked by the client when a session is switched to another session. This event allows client-side handlers to react to session switches, updating the user interface or internal state as necessary. ON_SESSION_SWITCH event takes the following eventData:

eventData	Description
previousSessionId	The session ID of the previous session.
newSessionId	The ID of the session that's now focused.

Example

// Define a handler function that's triggered when the session is switched
let sessionSwitchedHandlerFunction = function(eventInput) {
    // Log the previous and new session IDs to the console
    console.log("Previous session:  " + eventInput.data.previousSessionId +
                " - Current session: " + eventInput.data.newSessionId);

}; 
// Retrieve the event topic specific to session switching from the API
let sessionSwitchTopic = Microsoft.Apm.getEventPublisherTopic("ON_SESSION_SWITCH");
// Create a new broadcast channel to subscribe to session switch events
let sessionSwitchSubscriber = new BroadcastChannel(sessionSwitchTopic);
// Attach the session switched handler function to the message event of the subscriber
sessionSwitchSubscriber.onmessage = sessionSwitchedHandlerFunction;

Note

The code sample utilizes the Broadcast Channel API - Web APIs, to communicate between different documents such as pages or iframes that are of the same origin. Make sure it is compatible with your customization as support for this API can vary.
