HashChangeEvent: HashChangeEvent() constructor

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

See full compatibility

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

An object that, in addition to the properties defined in Event(), has the following properties:

oldURL Optional: A string containing the old URL. Its default value is the empty string ("").
newURL Optional: A string containing the new URL. Its default value is the empty string ("").

Return value

A new HashChangeEvent object.
