用于显示分页以指示一系列相关内容存在于多个页面的文档和示例。

概述

我们使用大量连接的链接进行分页，使链接不易错过且易于扩展，同时提供大的点击区域。分页是使用列表 HTML 元素构建的，因此屏幕阅读器可以宣布可用链接的数量。使用包装<nav>元素将其标识为屏幕阅读器和其他辅助技术的导航部分。

此外，由于页面可能有多个这样的导航部分，因此建议提供描述aria-label以<nav>反映其目的。例如，如果分页组件用于在一组搜索结果之间导航，则适当的标签可以是aria-label="Search results pages".

<nav aria-label="Page navigation example">
  <ul class="pagination">
    <li class="page-item"><a class="page-link" href="#">Previous</a></li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item"><a class="page-link" href="#">Next</a></li>
  </ul>
</nav>

使用图标

想要在某些分页链接中使用图标或符号代替文本？确保为aria属性提供适当的屏幕阅读器支持。

<nav aria-label="Page navigation example">
  <ul class="pagination">
    <li class="page-item">
      <a class="page-link" href="#" aria-label="Previous">
        <span aria-hidden="true">&laquo;</span>
      </a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#" aria-label="Next">
        <span aria-hidden="true">&raquo;</span>
      </a>
    </li>
  </ul>
</nav>

禁用和活动状态

分页链接可针对不同情况进行定制。用于.disabled出现不可点击的链接并.active指示当前页面。

虽然.disabled该类用于pointer-events: none尝试禁用s 的链接功能<a>，但该 CSS 属性尚未标准化并且不考虑键盘导航。因此，您应该始终添加tabindex="-1"禁用的链接并使用自定义 JavaScript 来完全禁用它们的功能。

<nav aria-label="...">
  <ul class="pagination">
    <li class="page-item disabled">
      <a class="page-link">Previous</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item active" aria-current="page">
      <a class="page-link" href="#">2</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>

您可以选择将活动或禁用的锚点换成<span>，或者在 prev/next 箭头的情况下省略锚点，以删除单击功能并防止键盘聚焦，同时保留预期的样式。

<nav aria-label="...">
  <ul class="pagination">
    <li class="page-item disabled">
      <span class="page-link">Previous</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item active" aria-current="page">
      <span class="page-link">2</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>

浆纱

想要更大或更小的分页？添加.pagination-lg或.pagination-sm用于其他尺寸。

<nav aria-label="...">
  <ul class="pagination pagination-lg">
    <li class="page-item active" aria-current="page">
      <span class="page-link">1</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
  </ul>
</nav>

<nav aria-label="...">
  <ul class="pagination pagination-sm">
    <li class="page-item active" aria-current="page">
      <span class="page-link">1</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
  </ul>
</nav>

结盟

使用flexbox 实用程序更改分页组件的对齐方式。

<nav aria-label="Page navigation example">
  <ul class="pagination justify-content-center">
    <li class="page-item disabled">
      <a class="page-link">Previous</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>

<nav aria-label="Page navigation example">
  <ul class="pagination justify-content-end">
    <li class="page-item disabled">
      <a class="page-link">Previous</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>
