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 getActive()
method of the HTMLIFrameElement
indicates whether the current browser <iframe>
is the currently active frame.
SyntaxEdit
var amIActive = instanceOfHTMLIframeElement.getActive();
Returns
A Boolean
indicating whether the current browser <iframe>
is the currently active frame (true
) or not (false
.)
Parameters
None.
ExampleEdit
var browser = document.querySelector('iframe');
var amIActive = browser.getActive();
SpecificationEdit
Not part of any specification.
Browser compatibilityEdit
Note: Use of the Browser API requires a privileged app, and browser
and/or embed-apps
permissions, depending on what you want to do. See Using the Browser API for more details.
