My use of innerHTML was only offered just in case he was going to be adding
multiple strings to the IFRAME not knowing that using document.write clears the
previously outputted text. I was hoping to head off future problems with the
same issue for a developer new to JavaScript.

Your solution is truly a correct solution too. I was just trying to help the new
guy.

Well, you can''t do what you just wrote because until you put something
in the iframe, there is no iFrame.contentWindow.document.body.  He asked about
creating a hidden iframe and writing to it, the solution I posted is the only
cross-browser solution that I''ve seen.  And you''d only lose
what was previously in the Iframe window, ie nothing, by overwriting it; the
parent document will not be affected.

The .src = ''/'' was a remnant from the code I was using to
avoid ''non-secure items on a secure page'' in IE, it can safely
be removed.

Important to remember that using document.open/close/write from javascript
during non-loading period will cause the current document context to reset,
meaning you lose what was previously there.

-          var iFrame = document.createElement(''IFRAME'');
-          iFrame.src = "/"; //pretty sure you don''t need
this
-          iFrame.contentWindow.document.body.innerHTML =
"blarrrrrrr";
-          iFrame.contentWindow.document.body.innerHTML += "more
BLARRRRRRRRR";

This should work:

        var iFrame   = document.createElement(''IFRAME'');
        iFrame.src = ''/'';
        iFrame.contentWindow.document.open();
        iFrame.contentWindow.document.write(sDocument);
        iFrame.contentWindow.document.close();

If I dynamically create a hidden iframe, how could I add a document in a string
to that element?

e.g.,

var sDocument = '' Hello
world. '';

I''ve tried several variations of appendChild, innerHTML,
document.innerHTML, createTextNode.

Argh!
