  <meta charset="UTF-8">
  <title>显示/隐藏div元素</title>
  <style>
    #myDiv {
      width: 200px;
      height: 200px;
      background-color: #ccc;
      display: block;
    }
  </style>
</head>

  <button onclick="toggleDiv()">显示/隐藏div元素</button>
  <div id="myDiv"></div>
  <script>
    function toggleDiv() {
      var div = document.getElementById("myDiv");
      if (div.style.display === "none") {
        div.style.display = "block";
      } else {
        div.style.display = "none";
      }
    }

If so, it is set to block. Otherwise set it to none. This implements the hiding and display of div elements.
