Embed JS/RJS from remote

I'm trying to make a widget for a page, that will go on other people's pages if they choose to do so.

What I am wanting to do, is have a resource like

map.resource :widget

So that localhost/widget is mapped to :controller => widget, :action => show, as is default with singular resource.

That way if someone browses to localhost/widget, they can see some html/erb explaining how to use the widget, and then if they

<script src="http://localhost/widget&quot; type="text/javascript"></script>

in there webpage, they can have the widget rendered on their page.

I thought I might be able to do this, by setting a respond_to in the show action like this:

def show    ....

   respond_to do |format|      format.html { do some normal html rendering }      format.js { render the widget }    end end

So then I created a file called show.rjs, and tried writing some very basic rjs, just to see if it would work, and it totally did not. So I tried a bunch of different approaches in the rjs file, especially the page << 'raw javascript' kind of thing, I really thought that was going to work, but no deal.

Also, I tried renaming show.rjs to just show.js, same thing nothing.

Does anyone know what I am doing wrong here? Does anyone know what a better solution for me would be?

Thanks for listening.
