In order to write into the iframe, you'll first need to create it, attach it to the document, and then reach inside of it to get a handle on its contentDocument.

Here is some sample code:

// create the iframe and attach it to the document
var iframe = document.createElement("iframe");
iframe.setAttribute("scrolling", "no");
iframe.setAttribute("frameborder", "0");
document.body.appendChild(iframe);

// find the iframe's document and write some content
var idocument = iframe.contentDocument;
idocument.open();
idocument.write("");
idocument.write("");
idocument.write("");
idocument.write("this is the iframe");
idocument.write("");
idocument.close();

// now have a look at your creation in the console
console.log(idocument);

See it working in this jsfiddle.
