이 기능이 있고 그 안에 addEventListener. 내가 줄 function (event){on_click(event, conteiner);}때이 EventListener를 제거 할 수 없지만 on_click 함수에 두 번째 매개 변수를 제공해야합니다.
delete_conteiner=function(which)
{
which.removeEventListener("click", function (event){on_click(event, conteiner);}, false);//this isn't working
document.body.removeChild(which);

on_click을 실행하는 EventListener를 추가하고 EventListener에서 제거하는 것이 가능합니까? 여기 전체 코드 :

이 removeEventListener()메서드는 메서드와 함께 연결된 이벤트 처리기를 제거합니다 addEventListener().
참고 : 이벤트 핸들러를 제거하려면addEventListener()메서드로지정된함수가 아래 예제 (click_event_func)와 같이 외부 함수 여야합니다.
