Delay your Javascript execution

There’s a Prototype helper method called delay, so you can more precisely say when something will happen.
For example, you can do stuff like this inside your RJS files:

page["old_element"].visual_effect :blind_up, :duration => 0.5

page.delay(0.5) do
  page.replace :old_element, :partial => "new_element"
  page["new_element"].visual_effect :blind_down
end

Check out the delay method.
