This example also uses the `beforeClose` attribute. It is a method and will be triggered when the MessageBox instance will be closed, and its execution will stop the instance from closing. It has three parameters: `action`, `instance` and `done`. Using it enables you to manipulate the instance before it closes, e.g. activating `loading` for confirm button; you can invoke the `done` method to close the MessageBox instance (if `done` is not called inside `beforeClose`, the instance will not be closed).

+## Notification

 Displays a global notification message at the upper right corner of the page.

 ### Basic usage

 ::: demo Element has registered the `$notify` method and it receives an object as its parameter. In the simplest case, you can set the `title` field and the` message` field for the title and body of the notification. By default, the notification automatically closes after 4500ms, but by setting `duration` you can control its duration. Specifically, if set to `0`, it will not close automatically. Note that `duration` receives a `Number` in milliseconds.
