Re: can someone pls tell me the ajax ways to do this like that?
Hi ! You need observe_field, which will observe changes to a specified DOM element. Then, you''ll need to use the :update attribute to specify which element should have it''s stuff replaced. You would usually use partials to accomplish the above. observe_field http://api.rubyonrails.com/classes/ActionView/Helpers/JavaScriptHelper.html#M000402 render :partial http://api.rubyonrails.com/classes/ActionController/Base.html#M000173 Bye !
