Question

我有一个汉堡包按钮，以便使用JS在我的HTML文件中显示侧边栏。基本上，这是一个<div>的代码段，一个小的JS代码以及一个包含实际汉堡包的<span>类。我想做的是将汉堡包按钮（虽然它不是由按钮类定义的）与标题对齐。我设法做到了，但是由于某种原因该按钮现在不起作用。有人可以告诉我为什么吗？还有其他方法可以将按钮与标头类内联吗？

<header class="header" style="width:100%" id="header">

    <div class="overlay-nav-content">

      <a href="#">About Us</a>
      <a href="#">Sessions</a>
      <a href="#">Competitions</a>
      <a href="#">Meetings</a>
    </div>
  </div>
  <span style="font-size:20px; cursor:pointer" onclick="openNav()">&#9776; </span>
  <script>
    function openNav() {
      document.getElementById("index").style.width = "100%";
    }

    function closeNav() {
      document.getElementById("index").style.width = "0%";
    }
  </script>

  <div class="header__logo">
    <img src="" alt="" />
    <h1></h1>
  </div>

P.S是否发生是因为指针事件未设置？

Answer 1

是的，这是因为您使用的是pointer-events: none，它将禁用任何由鼠标引起的事件。也许您的意思是使用pointer: none摆脱任何指针。

此外，我不确定您在opacity: 0类上拥有.header的原因，但这隐藏了该按钮甚至不可见。

Answer 2

您的指针事件：没有停止点击事件，并且您已将opacity：0应用于标题，因此它不显示，首先删除pointer-events: none;和opacity:1

    function closeNav() {

    }
  </script>

<header class="header" style="width:100%" id="header">
  <div class="loading"></div>
  <div id="index" class="overlay-nav">

    <div class="overlay-nav-content">

    </div>
  </div>
  <span style="font-size:20px; cursor:pointer" onclick="openNav()">&#9776; </span>


  <div class="header__logo">
    <img src="" alt="" />
    <h1></h1>
  </div>
  </header>

<span>按钮在标题类中不起作用吗？
