HashChangeEvent: HashChangeEvent() constructor

The HashChangeEvent() constructor creates a new HashChangeEvent object, that is used by the hashchange event fired at the window object when the fragment of the URL changes.

Note: A web developer doesn't typically need to call this constructor, as the browser creates these objects itself when firing hashchange events.

Syntax

new HashChangeEvent(type, options)

Parameters

type

A string with the name of the event. It is case-sensitive and browsers set it to hashchange.

options Optional

oldURL Optional

A string containing the old URL. Its default value is the empty string ("").

newURLOptional

A string containing the new URL. Its default value is the empty string ("").

Return value

A new HashChangeEvent object.
