Sorry for the late response, I tried to replace my javascript with this one :
Event.observe(window, "load", function() { Event.observe("chkAll", "click", function(event) { //var element = event.element(); $$("input.chk").each(function(aCheck) { aCheck.checked = $("chkAll").checked;//element.checked; }); }); }); It works perfectly, so the error comes from the event.element(), like you said. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
