极客教程Bootstrap 4分页
分页是用来在网站中实现页面之间的导航。Bootstrap中使用的分页有一大块连接的链接，很难错过，而且容易扩展。
基本分页：基本分页可以用以下类来指定。
- ..pagination类是用来指定列表组的分页。
- .page-item类用于指定组中的每个分页项目。
- .page-link类是用来指定分页项目中的链接。
示例:
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap 4 | Pagination</title>
<meta charset="utf-8">
<meta name="viewport"
content="width=device-width, initial-scale=1">
<link rel="stylesheet" href=
"https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<script src=
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<script src=

<body>
<div class="container">
<h1>Bootstrap 4 | Basic Pagination</h1>
<!-- Declare the pagination class -->
<ul class="pagination">
<!-- Declare the item in the group -->
<li class="page-item">
<!-- Declare the link of the item -->
<a class="page-link" href="#">Previous</a>
</li>
<!-- Rest of the pagination items -->
<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>
</div>
</body>
</html>
输出:
禁用状态：分页链接可以通过使用.disabled类来使它们看起来无法点击。这可用于禁用 “上一页 “或 “下一页 “按钮。.disabled类在内部使用 “指针事件：无 “来使链接不可点击，然而，由于这一规范并不总是被实施，最好是通过设置 “tabindex “属性为-1来使其不可能被导航到。这个属性控制一个元素是否可以用tab键来导航。
