One of the coolest things I ran across in RJS was the delay method. This delay method will do just that and delay a number of seconds. So lets say you need to highlight something that was just added to the page after the user submits it. I would like it to add to the page then wait 1 second and then highlight. The following is the code for that.

render :update do |page|
      page.html_replace 'testdiv', params[:the_text_added]
 
      page.delay(1) do 
        page.visual_effect :highlight, 'testdiv', :duration => 2
      end
end

Cool huh? Try it out and see what you can do with delay()!

Need more help with rails? Here is a great book that i recommend for all new and old rails developers: Beginning Ruby: From Novice to Professional
