Rails - Jul 2009 - AJAX/Javascript Question

What is the difference between these two:

render :js => "window.open(''#{url}'')


and 

render :update do |page|
  page << "window.open(''#{url}'')
end


TIA,
  Jeffrey

Actually, I am trying to update a element in a frame and open a new window wit
a specific URL.  The HTML is:

<%=link_to_remote article.title,
   :url => {:controller => ''three_pane'', :action =>
''click'', :id => article},
    :complete => ''eval(request.responseText)'' %>

The render in the action is:

render :update do |page|
  page << "window.open(''#{article.url}'')"
  page <<
"parent.feeds.document.getElementById(''#{dom_id(article.feed)}'').update(''#{content}'');"
end

The preceding code does the update AND opens two windows to article.url.  The
following code opens only one window, but doesn''t do the update.

  render :js => "window.open(''#{article.url}'')"

I don''t understand what''s going on.

TIA,
  Jeffrey
