分页

用于显示分页以指示跨多个页面存在一系列相关内容的文档和示例。

概述

¥Overview

我们使用大量连接的链接进行分页，使链接不易遗漏且易于扩展，同时提供较大的点击区域。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。使用封装 <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。

¥We use a large block of connected links for our pagination, making links hard to miss and easily scalable—all while providing large hit areas. Pagination is built with list HTML elements so screen readers can announce the number of available links. Use a wrapping <nav> element to identify it as a navigation section to screen readers and other assistive technologies.

此外，由于页面可能有多个此类导航部分，因此建议为 <nav> 提供描述性 aria-label 以反映其用途。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"。

¥In addition, as pages likely have more than one such navigation section, it’s advisable to provide a descriptive aria-label for the <nav> to reflect its purpose. For example, if the pagination component is used to navigate between a set of search results, an appropriate label could be aria-label="Search results pages".

html

<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

¥Working with icons

希望使用图标或符号代替某些分页链接的文本？请务必为 aria 属性提供适当的屏幕阅读器支持。

¥Looking to use an icon or symbol in place of text for some pagination links? Be sure to provide proper screen reader support with aria attributes.

html

<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

¥Disabled and active states

分页链接可针对不同情况进行定制。使用 .disabled 表示无法点击的链接，使用 .active 表示当前页面。

¥Pagination links are customizable for different circumstances. Use .disabled for links that appear un-clickable and .active to indicate the current page.

虽然 .disabled 类使用 pointer-events: none 尝试禁用 <a> 的链接功能，但该 CSS 属性尚未标准化，并且不考虑键盘导航。因此，你应该始终在禁用的链接上添加 tabindex="-1" 并使用自定义 JavaScript 来完全禁用其功能。

¥While the .disabled class uses pointer-events: none to try to disable the link functionality of <a>s, that CSS property is not yet standardized and doesn’t account for keyboard navigation. As such, you should always add tabindex="-1" on disabled links and use custom JavaScript to fully disable their functionality.

html

<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>

你可以选择将活动或禁用的锚点替换为 <span>，或者在上一个/下一个箭头的情况下省略锚点，以删除单击功能并防止键盘焦点，同时保留预期样式。

¥You can optionally swap out active or disabled anchors for <span>, or omit the anchor in the case of the prev/next arrows, to remove click functionality and prevent keyboard focus while retaining intended styles.

html

<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>

尺寸

¥Sizing

想要更大或更小的分页吗？添加 .pagination-lg 或 .pagination-sm 以获取其他尺寸。

¥Fancy larger or smaller pagination? Add .pagination-lg or .pagination-sm for additional sizes.

html

<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>

html

<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>

对其

¥Alignment

使用 flexbox 实用程序更改分页组件的对齐方式。例如，对于 .justify-content-center：

¥Change the alignment of pagination components with flexbox utilities. For example, with .justify-content-center:

html

<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>

或者使用 .justify-content-end：

¥Or with .justify-content-end:

html

<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>

CSS

变量

¥Variables

Added in v5.2.0

作为 Bootstrap 不断发展的 CSS 变量方法的一部分，分页现在使用 .pagination 上的本地 CSS 变量来增强实时自定义。CSS 变量的值是通过 Sass 设置的，因此仍然支持 Sass 自定义。

¥As part of Bootstrap’s evolving CSS variables approach, pagination now uses local CSS variables on .pagination for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
