如何创建：标签页标题

学习如何使用 CSS 和 JavaScript 创建标签页标题。

创建可切换的标签页标题

第一步 - 添加 HTML：

<div id="London" class="tabcontent">
  <h1>London</h1>
  <p>London is the capital city of England.</p>
</div>

<div id="Paris" class="tabcontent">
  <h1>Paris</h1>
  <p>Paris is the capital of France.</p>
</div>

<div id="Tokyo" class="tabcontent">
  <h1>Tokyo</h1>
  <p>Tokyo is the capital of Japan.</p>
</div>

<div id="Oslo" class="tabcontent">
  <h1>Oslo</h1>
  <p>Oslo is the capital of Norway.</p>
</div>

<button class="tablink" onclick="openCity('London', this, 'red')" id="defaultOpen">London</button>
<button class="tablink" onclick="openCity('Paris', this, 'green')">Paris</button>
<button class="tablink" onclick="openCity('Tokyo', this, 'blue')">Tokyo</button>
<button class="tablink" onclick="openCity('Oslo', this, 'orange')">Oslo</button>
Create buttons to open specific tab content. All <div> elements with class="tabcontent" are hidden by default (with CSS & JS). When the user clicks on a button - it will open the tab content that "matches" this button.

第二步 - 添加 CSS：

设置按钮和标签页内容的样式：

/* 设置标签页按钮的样式 */
.tablink {
  background-color: #555;
  color: white;
  float: left;
  border: none;
  outline: none;
  cursor: pointer;
  padding: 14px 16px;
  font-size: 17px;
  width: 25%;
}

/* 更改悬停时按钮的背景颜色 */
.tablink:hover {
  background-color: #777;
}

/* 设置标签页内容的默认样式 */
.tabcontent {
  color: white;
  display: none;
  padding: 50px;
  text-align: center;
}

/* 单独设置每个标签页内容的样式 */
#London {background-color:red;}
#Paris {background-color:green;}
#Tokyo {background-color:blue;}
#Oslo {background-color:orange;}

第三步 - 添加 JavaScript：

function openCity(cityName, elmnt, color) {
  // 默认隐藏所有 class="tabcontent" 的元素 */
  var i, tabcontent, tablinks;
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }

  // 删除所有标签页链接/按钮的背景颜色
  tablinks = document.getElementsByClassName("tablink");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].style.backgroundColor = "";
  }

  // 显示具体标签页内容
  document.getElementById(cityName).style.display = "block";

  // 为用于打开标签页内容的按钮添加特定的颜色
  elmnt.style.backgroundColor = color;
}

// 获取 id="defaultOpen" 的元素并点击它
document.getElementById("defaultOpen").click();
