概述
我們使用一大塊連接的鏈接進(jìn)行分頁，使得鏈接很難丟失，并且很容易擴(kuò)展，同時(shí)提供了較大的命中區(qū)域。分頁是用列表HTML元素構(gòu)建的，因此屏幕閱讀器可以宣布可用鏈接的數(shù)量。使用包裝nav元素將其標(biāo)識(shí)為用于屏幕閱讀器和其他輔助技術(shù)的導(dǎo)航部分。
此外，由于頁面可能有多個(gè)這樣的導(dǎo)航部分，建議為
<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>使用圖標(biāo)
要使用圖標(biāo)或符號(hào)來代替某些分頁鏈接的文本嗎？確保使用aria屬性提供適當(dāng)?shù)钠聊婚喿x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">«</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">»</span>
</a>
</li>
</ul>
</nav>禁用和活動(dòng)狀態(tài)
分頁鏈接可根據(jù)不同情況進(jìn)行自定義。對(duì)于顯示為不可單擊的鏈接使用.disabled，對(duì)于顯示為當(dāng)前頁的鏈接使用.active。
雖然.disabled類使用pointer-events: none來嘗試禁用a的鏈接功能，但是CSS屬性還沒有標(biāo)準(zhǔn)化，并且不考慮鍵盤導(dǎo)航。因此，您應(yīng)該始終在禁用的鏈接上添加tabindex="-1"，并使用自定義JavaScript完全禁用其功能。
<nav aria-label="...">
<ul class="pagination">
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1" aria-disabled="true">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>您可以選擇調(diào)出span的活動(dòng)或禁用的錨定，或者在上一個(gè)/下一個(gè)箭頭的情況下忽略錨定，以刪除單擊功能并防止鍵盤聚焦，同時(shí)保留所需的樣式。
<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>大小
喜歡更大或更小的分頁？加上.pagination-lg 或者 .pagination-sm，或使用其他尺寸。
<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>對(duì)齊
使用flexbox實(shí)用程序更改分頁組件的對(duì)齊方式。
