HTMLIFrameElement.setActive()

Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

This API is available on Firefox OS for privileged or certified applications only.

The setActive() method of the HTMLIFrameElement sets the current <iframe> as the active frame, which has an effect on how it is prioritized by the process manager.

Syntax

instanceOfHTMLIframeElement.setActive(boolean);

Returns

Void.

Parameters

boolean
A Boolean that indicates whether the iframe is to be the active frame (true) or not (false).

Example

var browser = document.querySelector('iframe');
browser.setActive();

Specification

Not part of any specification.
