문제점 : 자식 이벤트 (파일)를 실행하려고하면 부모 이벤트가 파일 (파일)을 실행합니다.Backbone.js에서 중첩 된 모델 이벤트 발생
나의 관계는 다음과 같이이다 : Project ---> (Many)Files(If is only folder) ---> (Many)Files and so on(If is only folder)
내 생각은 Backbone.Js를 사용하여 폴더 트리를 구성하는 것입니다.
내 코드는 다음과 같이
(function ($){

} ,

return (this.get("state") === "collapsed");
