The data read-only property of the Notification interface returns a structured clone of the notification's data, as specified in the data option of the Notification() constructor.

The notification's data can be any arbitrary data that you want associated with the notification.

Note: This feature is available in Web Workers.

Syntax

var data = Notification.data;

Value

A structured clone.

Examples

The following snippet fires a notification; a simple options object is created, then the notification is fired using the Notification() constructor.

var options = {
  body: 'Do you like my body?',
  data: 'I like peas.'
}

var n = new Notification('Test notification',options);

n.data // should return 'I like peas.'
