RJS in action vs .js file (page object)

Hi,

Would anyone be able to suggest why the following works in the action
but not when placed in a .js file, called by the action?

It's the page << "$('basket_popup').popup.show();" line I'm interested
in.

def show

    respond_to do |format|
      format.js do
        render :showbasket do |page|
          page << "$('basket_popup').popup.show();"
        end
      end
    end

end

However when I have show.js and remove the block from format.js it
fails. I get a javascript error on the page along the lines of popup
has no properties/attributes?

-show.js-

page << "$('basket_popup').popup.show();"

I'm sure it's a simple one but I can't see it??

Name your file show.js.rjs so Rails knows to use the RJS renderer to render it into the page. Might be as simple as that.

Best regards
