Переход экрана вкл / выкл div

Question

Я работал над созданием базовой платформы для мобильных сайтов. Я столкнулся с проблемой с переходами. У меня есть закадровый div, который переходит к тому, чтобы быть на экране при нажатии кнопки меню (в правом верхнем углу веб-сайта). Он также переходит обратно за экран при повторном нажатии кнопки. Это работает нормально, пока переполнение не скрыто.

Я хочу скрыть переполнение, но div только переходит, если отображается переполнение. Любые идеи для лучшего способа справиться с этим?

    var clicked = false;
    
    function mobileNav() {
      var doc = document.getElementsByClassName("innerMenu")[0];
      if(clicked){
        if(doc.classList.contains("transitionIn")) {
          doc.classList.remove("transitionIn");
        }
        doc.classList.add("transitionOut");
      }
      else {
        if(doc.classList.contains("transitionOut")) {
          doc.classList.remove("transitionOut");
        }
        doc.classList.add("transitionIn");
      }
      clicked = !clicked;
    }

Answer 1

Вы можете скрыть прокрутку для оси x для тела, затем использовать javascript, чтобы добавить и скрыть прокрутку для внешнего меню при добавлении перехода css во внутреннее меню.

    var clicked = false;
    
    function mobileNav() {
      var doc = document.getElementsByClassName("innerMenu")[0];
      var outermenu = document.getElementsByClassName("outerMenu")[0];
      if(clicked){
        if(doc.classList.contains("transitionIn")) {
          doc.classList.remove("transitionIn");
        }
        doc.classList.add("transitionOut");
        setTimeout(function(){
           outermenu.style.overflow = "hidden !important";
        },1000);
      }
      else {
        if(doc.classList.contains("transitionOut")) {
          doc.classList.remove("transitionOut");
        }
        outermenu.style.overflow = "visible !important";
        doc.classList.add("transitionIn");
      }
      clicked = !clicked;
    }
