PageSwapEvent: PageSwapEvent() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

See full compatibility

The PageSwapEvent() constructor creates a new PageSwapEvent object instance.

Syntax

new PageSwapEvent(type, init)

Parameters

type

A string representing the type of event. In the case of PageSwapEvent this is always pageswap.

init

An object containing the following properties:

activation: A NavigationActivation object representing the navigation type and current and destination document history entries. Defaults to null if the associated navigation is a cross-origin navigation.
viewTransition: A ViewTransition object representing the active view transition for the related navigation. Defaults to null if there is no active view transition.

Examples

A developer would not use this constructor manually. A new PageSwapEvent object is constructed when a handler is invoked as a result of the pageswap event firing.
