Rails - Nov 2006 - Setting Ajax.Updater update target to alternate window?

I need to make a call to Ajax.Updater(container, url, options) where 
container needs to be a DOM element in another window.

So assuming my form is in window "X", can I specify a DOM element in 
window "Y" as the update target for my AJAX call?

If I can, what is the correct syntax?

Thanks,
Wes

Alternatively, I''m interested in how to dynamically add a form to a 
document using the DOM in Javascript.

I''m trying

	newForm = document.createElement(''form'');

but doesn''t seem to be showing up in the document forms array.

Thanks,
Wes

I ended up with the Javascript function below.

This:
* Opens a popup
* Adds a DIV with wait message and graphic
* Submits the form request
* Eval''s the response from the form request which is something along
the
lines of:

page.assign(''popup.location.href'',
''...data...'')

which takes the output of the form submission and renders to the 
browser.

=========================================================================
function submit_form_to_popup(form, popup_window_name, action) {
  form.action = action;
  popup = window.open('''', popup_window_name,
''width=800, height=700,
left = 450, top = 100, resizable, scrollbars=yes'');
  wait_image_url = window.location.protocol + ''//'' + 
window.location.host + ''/images/indicator_verybig.gif'';

//Create a DIV in the popup window and populate it with the AJAX wait 
message and graphic.
  newDiv = popup.document.createElement(''div'');
  newDiv.setAttribute(''id'', ''pdf'');
  newDiv.setAttribute(''style'', ''margin-top: 250px;
text-align:
center;'');
  newDiv.innerHTML = ''Please wait while your forms are 
generated<BR/><BR/><IMG src="'' + wait_image_url +
''"/>'';
  popup.document.body.appendChild(newDiv);

//Submit the form asynchronously and execute Javascript returned from 
the action.
  new Ajax.Request(form.action, { asynchronous: true, 									method: 
''post'', 									parameters: Form.serialize(form), 						
evalScripts:
true,
				onSuccess: function(request) 
{eval(request.responseText);}
                   });
	return false;
}
