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 goBack() method of the HTMLIFrameElement interface is used to navigate backwards in the browser <iframe>'s history.
By calling this method, the browser <iframe> changes its location for the previous location available in its navigation history, which sends a series of related events: mozbrowserlocationchange, mozbrowserloadstart, and so on.
Syntax
instanceOfHTMLIframeElement.goBack();
Returns
Void.
Parameters
None.
Examples
back.addEventListener('touchend',function() {
browser.goBack();
});
Specification
Not part of any specification.
