Unsubscribing from a Canvas App Event

Unsubscribing from a Custom Event

The following code example shows how to call the unsubscribe method to unsubscribe from a canvas app event.

// Unsubscribe from a custom event.
Sfdc.canvas(function() {
    sr = JSON.parse('<%=signedRequestJson%>');
    Sfdc.canvas.client.unsubscribe(sr.client, {name : "mynamespace.statusChanged"});
});

Unsubscribing from Multiple Custom Events

The following code example shows how to call the unsubscribe method to unsubscribe from multiple canvas app events. The events you subscribe to can be in different namespaces or might not have a namespace.

// Unsubscribe from multiple events.
Sfdc.canvas(function() {
    sr = JSON.parse('<%=signedRequestJson%>');
    Sfdc.canvas.client.unsubscribe(sr.client, ['mynamespace.statusChanged', "anothernamespace.tripCancelled"]);
});
