Top of my head and not tested, you could also use #invoke, which is simpler: $$('.extrainfo').invoke('observe', 'change', myfunction); Notice that you should not execute myfunction(), but pass reference to it to #observe method (unless myfunction(id) returns reference to a function). myfunction will be called with event as first parameter, so you will have to check Event.findElement() to check which <select> was changed, e.g: function myfunction(evnt) { //should alert id of changed <select> alert (Event.findElement(evnt).id); } See Enumerable#invoke docs for details. -- Regards, SWilk --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
