Then your <%= %> will expand to be whatever the local value of @user is at the moment that script is requested.

If your controller had a respond_to block in it, and your JavaScript file was named sensibly for the controller method, then this would Just Workâ˘, respond_to do |format| format.js { render :layout => false } format.html end Walter>> -- > You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group. > To unsubscribe from this group and stop receiving emails from it, send an email to rubyonrails-talk+unsubscribe-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To post to this group, send email to rubyonrails-talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To view this discussion on the web visit https://groups.google.com/d/msgid/rubyonrails-talk/CADKeJyTqA%3DZ44f1RQeTtm5j8%3DpXQMessnu%3DEpm4WTMDGu33jbA%40mail.gmail.com. > For more options, visit https://groups.google.com/groups/opt_out.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
