Rails 애플리케이션에 JQuery 기능을 추가하려고합니다. 그러나 작동하지 않습니다. JQuery draggable을 사용하여 화면에서 이미지를 이동합니다. 독립형 HTML 파일로 작업하고 있지만 레일스 응용 프로그램에 추가하는 데 많은 어려움을 겪고 있습니다. 이것은 독립 실행 형 파일 : 나는 자산/자바 스크립트/custom_map.js에서 자바 스크립트를 배치 한JQuery 기능 추가

그리고 내 new_map.html.erb보기에서 HTML/CSS를 배치했다. 이미지는 Rails 앱에서 잘 보이지만 드래그 할 수는 없습니다. 이 문제를 어떻게 해결할 수 있습니까? 감사!
