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.
