How to clear the content of an IFRAME?

Question

How do I clear the content of my IFRAME element, using javascript, without loading a blank page into it?

I can figure out to do this: iframe_element.src = \"bl

Answer 1

Just get the Iframe and remove the documentElement from it. The Iframe will be blank

 var frame = document.getElementById("YourFrameId"),
 frameDoc = frame.contentDocument || frame.contentWindow.document;
 frameDoc.removeChild(frameDoc.documentElement);
