저 클래스 컨텍트를 클릭할떄마다 햄버거 메뉴가 번형이 됬다 안됬다 하고 싶습니다.

    <label>
          <input type='checkbox' class='toggle'>
          <span class='menu'>
              <span class='hamburger'></span>
          </span>
      </label>

위 라벨이 햄버거 메뉴 입니다. 생각했던것보다 잘 안되네여

 스크립트는 이런식으로 되어있습니다.  

  var bring_nav = function () {
                $('.content').toggleClass('content__move');
                $('nav').toggleClass('nav__move');
            };

            var go_to_section = function () {
                var id = $(this).attr('class');
                $('section').removeClass('section_open');
                $('section#' + id).addClass('section_open');
                bring_nav();
            };
            var transform

            $(document).ready(function () {
                $('.toggle').on('click', bring_nav);
                $('nav').find('button').on('click', go_to_section);
            });
        })
