javascript - 聊天框包装器 block 单击按钮

Question

我有一个聊天框，可以在点击按钮时显示和隐藏。
例如，我有一些页面在聊天框后面有一些按钮。
在这个例子中，按钮是不可点击的。
我该如何解决？聊天框甚至没有打开，按钮仍然不可点击。
我希望当我的聊天关闭时按钮可以点击。
我试着这样做:

.wrap {
    bottom: 1em;
    display: flex;
    flex-direction: column;
    position: fixed;
    right: 1em;
    z-index: -99; //////// doesn't work
 }

它怎么会出现在我的按钮前面？
这里有我的聊天示例和示例按钮。

    const btn = document.querySelector(".js-chat");

  const chatBox = document.querySelector(".js-chatbox");
  $("#chat-circle").click(function() {    
    $("#chat-circle").toggle('scale');
    $(".chat-box").toggle('scale');
  });

  $(".chat-box-toggle").click(function() {
    $("#chat-circle").toggle('scale');
    $(".chat-box").toggle('scale');
  });

  btn.addEventListener("click", () => {
      chatBox.classList.toggle("chatbox--is-visible");

      if (chatBox.classList.contains("chatbox--is-visible")) {
          btn.innerHTML = '<i class="fa fa-times"></i>';
      } else {
          btn.innerHTML = '<i class="fa fa-comments"></i>';
      }
  });

Answer 1

Scale 函数就是这样做的，因为它保持它的位置，即使它设置为 0 它仍然具有完整的宽度和高度。不透明度使它只是不可见但仍然保持位置。

如果你想要很酷的效果，不要使用 css class 而使用 jquery funcion .fadeToggle() .
