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

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.
