ScreenOrientation: unlock() method

Limited availability

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

The unlock() method of the ScreenOrientation interface unlocks the orientation of the containing document, effectively locking it to the default screen orientation.

Syntax

js
unlock()

Parameters

None.

Return value

None (undefined).

Exceptions

InvalidStateError DOMException

Thrown if the document is not fully active.

SecurityError DOMException

Thrown if the document's visibility state is hidden or if the document is forbidden to use the feature (for example, by omitting the keyword allow-orientation-lock of the sandbox attribute of the iframe element).
