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 getContentDimensions() method of the HTMLIFrameElement interface retrieves the X and Y dimensions of the content window.
Note: The values returned are equivalent to document.body.scrollWidth and document.body.scrollHeight.
Syntax
var instanceOfDOMRequest = instanceOfHTMLIframeElement.getContentDimensions();
Returns
A DOMRequest for handling the dimensions request. Its request.onsuccess handler handles the success case, and its request.onerror handler handles the failure case.
The X and Y dimensions are available in the request.result.x and request.result.y properties, respectively.
Parameters
None.
Examples
var browser = document.querySelector('iframe'); var request = browser.getContentDimensions(); request.onsuccess = function() { console.log("page size:", request.result.width + "x" + request.result.height); } request.onerror = function() { console.log("Download error"); }
Specification
Not part of any specification.
