access the content of a about:blank iframe

From the Firebug JavaScript console is it possible to access the content of an <iframe> object whose src property is set to about:blank? I've tried with:

var b=document.getElementById("iframe_ID");
console.log(b.innerHTML);

but it returns

(an empty string)

With document.getElementById("iframe_ID").innerHTML you just get the HTML content within the iframe element of the current document, not the iframe's document. I.e. if you have your iframe defined like this:

<iframe src="someDocument.html" id="iframe_ID"></iframe>

you get the contents between the opening <iframe> tag and the closing </iframe> tag, i.e. an empty string in this case.

To access the iframe's content you need to call this:

document.getElementById("iframe_ID").contentDocument.documentElement.innerHTML

See also Accessing the document object of a frame with JavaScript.

Though note that there are some security restrictions when trying to access the iframe's content as described in an answer to a similar topic.
