如何创建：可悬停标签页

学习如何使用 CSS 和 JavaScript 在鼠标悬停时切换标签页。

创建可悬停的垂直标签页

第一步 - 添加 HTML：

<div class="tab">
  <button class="tablinks" onmouseover="openCity(event, 'London')">London</button>
  <button class="tablinks" onmouseover="openCity(event, 'Paris')">Paris</button>
  <button class="tablinks" onmouseover="openCity(event, 'Tokyo')">Tokyo</button>
</div>
<div id="London" class="tabcontent">
  <h3>London</h3>
  <p>London is the capital city of England.</p>
</div>
<div id="Paris" class="tabcontent">
  <h3>Paris</h3>
  <p>Paris is the capital of France.</p>
</div>
<div id="Tokyo" class="tabcontent">
  <h3>Tokyo</h3>
  <p>Tokyo is the capital of Japan.</p>
</div>

创建按钮以打开特定的标签页内容。所有带有 class="tabcontent" 的 <div> 元素默认都是隐藏的（通过 CSS 和 JS）。当用户将鼠标悬停在按钮上时，它将打开与该按钮“匹配”的标签页内容。

第二步 - 添加 CSS：

设置按钮和标签页内容的样式：

/* 设置标签页的样式 */
.tab {
  float: left;
  border: 1px solid #ccc;
  background-color: #f1f1f1;
  width: 30%;
  height: 300px;
}
/* 设置用于打开标签页内容的按钮的样式 */
.tab button {
  display: block;
  background-color: inherit;
  color: black;
  padding: 22px 16px;
  width: 100%;
  border: none;
  outline: none;
  text-align: left;
  cursor: pointer;
}
/* A wuce wata a cikin rarrabu a lokacin da kwanan ya shiga */
.tab button:hover {
  background-color: #ddd;
}
/* A tsara rarrabu "tab button" mai yin nasara/yanzuwa */
.tab button.active {
  background-color: #ccc;
}
/* A ganiya saman taba kuma a ganiya saman yankecin kwayar taba */
.tabcontent {
  float: left;
  padding: 0px 12px;
  border: 1px solid #ccc;
  width: 70%;
  border-left: none;
  height: 300px;
  display: none;
}

Na tsawon uku - A dace JavaScript:

function openCity(evt, cityName) {
  // A yankeci dukkan nau'ikan
  var i, tabcontent, tablinks;
  // A samu kowace abin da ke da class="tabcontent" kuma a kawar da su
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  // A samu kowace abin da ke da class="tablinks" kuma a kawar da rarrabu "active"
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }
  // Tunanin da yana tabba na yanki, kuma a dace "active" rarrabu ga cikin likiti da ya fahimci tabba
  document.getElementById(cityName).style.display = "block";
  evt.currentTarget.className += " active";
}
