The requestWindow() method of the DocumentPictureInPicture interface opens the Picture-in-Picture window for the current main browsing context. It returns a Promise that fulfills with a Window instance representing the browsing context inside the Picture-in-Picture window.

The requestWindow() method requires transient activation, i.e. it must be invoked in response to a user action such as a mouse click or button press.

Syntax

js
requestWindow()
requestWindow(options)

Parameters

options Optional

An options object containing the following properties:

height

A non-negative number representing the height to set for the Picture-in-Picture window's viewport, in pixels. If options is not specified, the default value 0 is used.

width

A non-negative number representing the width to set for the Picture-in-Picture window's viewport, in pixels. If options is not specified, the default value 0 is used.

Note: If one of the options is specified, the other one must be too, otherwise an error is thrown. If both values are not specified, specified as 0, or set too large, the browser will clamp or ignore the values as appropriate to provide a reasonable user experience. The clamped size will vary depending on implementation, display size, and other factors.

Return value

A Promise that fulfills with a Window object instance representing the browsing context inside the Picture-in-Picture window.

Exceptions

NotSupportedError DOMException

Thrown if the API has been explicitly disabled (for example via browser settings).

NotAllowedError DOMException

Thrown if:

RangeError DOMException

Thrown if only one of height and width are set, or if height and width are set with negative values.
