{{APIRef("Web Notifications")}}{{AvailableInWorkers}}{{securecontext_header}}

The **`onerror`** property of the {{domxref("Notification")}}
interface specifies an event listener to receive {{domxref("Element/error_event", "error")}} events.
These events occur when something goes wrong with a {{domxref("Notification")}}
(in many cases an error preventing the notification from being displayed.)

## Syntax

Notification.onerror = function() { ... };
