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;}

Answer 1

您的 HTML 代码无效。

改变这个

<div class="popup">

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

</div>

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

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

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

</div>

对此

<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>
