Name

PageTransitionEvent — event object for pageshow and pagehide events

Inherits from

Event

Synopsis

Browsers fire a pageshow event after the load event when a document first loads, and then fire another pageshow event each time the page is restored from the in-memory history cache. A PageTransitionEvent object is associated with each pageshow event, and its persisted property is true if the page is being restored rather than loaded or reloaded.

Pagehide events also have an associated PageTransitionEvent object, but the persisted property is always true for pagehide events.

Pageshow and pagehide events are triggered on the Window object. They do not bubble and have no default action to cancel.

Properties

readonly boolean persisted

For pageshow events, this property is false if the page was loaded (or reloaded) from the network or the disk cache. It is true if the page being shown was restored from the in-memory cache without being reloaded.

For pagehide events, this property is always true.
