BackButton.addEventListener method

Registers an event handler for the specified event.

Syntax

backButton.addEventListener(type, listener, useCapture);

type
Type: String

The event type (name) to register.
listener
Type: Function

The event handler function to associate with the event.
useCapture
Type: Boolean

Set to true to register the event handler for the capturing phase; otherwise, set to false to register the event handler for the bubbling phase. For more information, see Event capture and event bubbling with DOM events.

This method does not return a value.

To set an event handler declaratively, it must be accessible to the global scope, and you must also call WinJS.Utilities.markSupportedForProcessing or WinJS.UI.eventHandler on the handler. You can make the handler accessible to the global scope by using WinJS.Namespace.define. For more information, see How to set event handlers declaratively.
