如何仅在单击按钮时显示元素(例如: slidebar)

Question

我正在为一个学校项目创建一个小网站，但我无法做到这样，当你点击侧边栏中的一个按钮时，它会显示一个“弹出窗口”，例如在这里我想让你点击演示文稿按钮(顶部的第二个按钮)，它会显示幻灯片，如果你点击另一个按钮，比如主页按钮，它就不会显示它。有谁可以帮我？

​

    <script type="text/javascript">
    var slides = document.querySelectorAll('.slide');
    var btns = document.querySelectorAll('.btn');
    let currentSlide = 1;

    // Javascript for image slider manual navigation
    var manualNav = function(manual){
      slides.forEach((slide) => {
        slide.classList.remove('active');

        btns.forEach((btn) => {
          btn.classList.remove('active');
        });
      });

      slides[manual].classList.add('active');
      btns[manual].classList.add('active');
    }

    btns.forEach((btn, i) => {
      btn.addEventListener("click", () => {
        manualNav(i);
        currentSlide = i;
      });
    });
    </script>

我很确定我有你想要的功能。我所做的是创建一个新函数，在单击每个导航按钮以从所选元素中删除一个非活动类时调用该函数，并将一个非活动类添加到其他可导航元素中。也许有一种更好的方法来将其与您当前的“onclick”功能集成，但这只是我的快速尝试。这里只包含我的主要更改，但是这里有一个指向代码依赖程序的链接：https://codepen.io/jarellh94/pen/MWQyxVX

index.html：

...
<li class="list">
      <b></b>
      <b></b>
      <a href="#" onclick=toggleElement("img-slider")>
        <span class="icon">
          <ion-icon name="easel-outline"></ion-icon>
        </span>
        <span class="title">Présentation</span>
      </a>
    </li>
...
function toggleElement(elem) {
    let navigatableList = document.querySelectorAll(".navigatable")
    navigatableList.forEach(element => {
      if(element.classList.contains(elem)) {
        element.classList.remove("inactive")
      } else {
        element.classList.add("inactive")
      }
    })
  }

style.css：

...
.inactive {
    display: none;
  }

  .img-slider{
    position: absolute;
    width: 800px;
    height: 500px;
    left: 500px;
    top: 200px;
    margin: 10px;
    background-color: blue;
    z-index: 100;
  }
