前端一个div实现通过标签栏进行切换

可以使用以下方式实现：

HTML代码：

<div class="tab-container">
  <div class="tab">
    <button class="tablinks" onclick="openTab(event, 'tab1')">Tab 1</button>
    <button class="tablinks" onclick="openTab(event, 'tab2')">Tab 2</button>
    <button class="tablinks" onclick="openTab(event, 'tab3')">Tab 3</button>
  </div>
  
  <div id="tab1" class="tabcontent">
    <h2>Tab 1 Content</h2>
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed blandit, augue vel consequat lobortis, libero arcu maximus risus, eget malesuada eros sapien sed justo. </p>
  </div>
  
  <div id="tab2" class="tabcontent">
    <h2>Tab 2 Content</h2>
    <p>Nunc euismod, dui vel ultrices bibendum, eros purus luctus odio, ac rhoncus tortor velit vel metus. Fusce nec massa euismod, dignissim magna sit amet, efficitur purus. </p>
  </div>
  
  <div id="tab3" class="tabcontent">
    <h2>Tab 3 Content</h2>
    <p>Phasellus eu tempor velit. Maecenas consectetur euismod dolor, id sagittis arcu congue vel. Sed commodo, neque id volutpat convallis, arcu sapien ultrices augue, at volutpat justo elit ut risus. </p>
  </div>
</div>

CSS代码：

/* 隐藏所有tabcontent */
.tabcontent {
  display: none;
}

/* 显示当前tabcontent */
.active {
  display: block;
}

/* 标签栏样式 */
.tab {
  overflow: hidden;
  border: 1px solid #ccc;
  background-color: #f1f1f1;
}

.tab button {
  background-color: inherit;
  border: none;
  outline: none;
  cursor: pointer;
  padding: 14px 16px;
  transition: 0.3s;
}

.tab button:hover {
  background-color: #ddd;
}

.tab button.active {
  background-color: #ccc;
}

/* 控制标签切换 */
.tabcontent {
  animation: fadeEffect 1s;
}

@keyframes fadeEffect {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

JavaScript代码：

// 默认显示第一个tab
document.getElementById("tab1").classList.add("active");

function openTab(evt, tabName) {
  var i, tabcontent, tablinks;
  
  // 隐藏所有的tabcontent
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].classList.remove("active");
  }
  
  // 取消所有的tablinks的选中状态
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].classList.remove("active");
  }
  
  // 显示当前点击的tab和设置选中状态
  document.getElementById(tabName).classList.add("active");
  evt.currentTarget.classList.add("active");
}

以上代码实现了一个简单的标签切换功能，可以根据需要进行修改和扩展。
