无法显示 JavaScript 弹出窗口

Question

我正在尝试使用 JavaScript 显示一个弹出窗口，但是，带有 class="popup" 的 div 是当前显示的唯一内容。当用户执行一个动作时，popup 和 popup2 都应该显示。我不确定我做错了什么。

HTML：

<div class="popup">

  <span class="popuptext" id="popup"></span>

</div>

<div class="popup2">

    <div class="popup2text" id="popup2"></div>

    <script src="/popup2.js"></script>

</div>

JavaScript：

$(() => {

  $('#enter').on('keypress', function(e) {

    if (e.keyCode == 13) {

      const newTask = $(this).val();

      if (newTask) {

上面的javascript部分可以忽略

        var popup = document.getElementById("popup");

        popup.classList.toggle("show");

        var popup2 = document.getElementById("popup2");

        popup2.classList.toggle("show");

      }

    }

  });

});

CSS：

.popup {

  position: relative;

  display: inline-block;

  cursor: pointer;

  -webkit-user-select: none;

  -moz-user-select: none;

  -ms-user-select: none;

  user-select: none;

}

.popuptext {

  visibility: hidden;

  width: 160px;

  height: 200px;

  background-color: #131313;

  color: #fff;

  opacity: 0.95;

  text-align: center;

  border-radius: 6px;

  padding: 8px 0;

  position: absolute;

  z-index: 1;

  left: 581px;

  top: 180px;

  margin-left: -80px;

}

.popup .show {

  visibility: visible;

  -webkit-animation: fadeIn 0.5s;

  animation: fadeIn 0.5s;

}

@-webkit-keyframes fadeIn {

  from {opacity: 0;} 

  to {opacity: 1;}

}

@keyframes fadeIn {

  from {opacity: 0;}

  to {opacity:1 ;}

}

#popup2 {

  visibility: hidden;

  color: white;

  font-family: 'Quicksand', sans-serif;

  font-size: 50px;

  top: 50px;

  left: 50px;

  -webkit-user-select: none;

  -moz-user-select: none;

  -ms-user-select: none;

  user-select: none;

}

#popup2 .show {

  visibility: visible;

  -webkit-animation: fadeIn 0.5s;

  animation: fadeIn 0.5s;

}

您的 HTML 代码无效。改变这个<div class="popup">&nbsp; <span class="popuptext" id="popup"></span></div><div class="popup2"></div>&nbsp; &nbsp; <div class="popup2text" id="popup2"></div>&nbsp; &nbsp; <script src="/popup2.js"></script></div>对此<div class="popup">&nbsp; <span class="popuptext" id="popup"></span></div><div class="popup2">&nbsp; &nbsp; <div class="popup2text" id="popup2"></div>&nbsp; &nbsp; <script src="/popup2.js"></script></div>
