列表组(List group)

列表组是用于显示一系列内容的灵活而强大的组件。 修改并扩展它们以支持其中的几乎所有内容。

基础例子

最基本的列表组是具有列表项和适当类的无序列表。 使用其后的选项或根据需要使用自己的CSS来构建它。

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

激活项目

将.active添加到.list-group-item中,以指示当前的活动选择。

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group">
  <li class="list-group-item active">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

禁用项目

.disabled添加到.list-group-item使其_appear_禁用。 请注意,某些带有.disabled元素的元素还需要自定义JavaScript才能完全禁用其点击事件(例如,链接)。

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group">
  <li class="list-group-item disabled" aria-disabled="true">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

链接和按钮

通过添加.list-group-item-action,使用<a>s或<button>s创建具有悬浮,禁用和活动状态的_actionable_列表组项目。 我们将这些伪类分开,以确保由非交互式元素(如<li>s或<div>s)组成的列表组不提供点击或点击功能。

请确保不要在此处使用标准的.btn类。

<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action active">
    Cras justo odio
  </a>
  <a href="#" class="list-group-item list-group-item-action">Dapibus ac facilisis in</a>
  <a href="#" class="list-group-item list-group-item-action">Morbi leo risus</a>
  <a href="#" class="list-group-item list-group-item-action">Porta ac consectetur ac</a>
  <a href="#" class="list-group-item list-group-item-action disabled" tabindex="-1" aria-disabled="true">Vestibulum at eros</a>
</div>

使用<button>s,您还可以使用disabled属性代替.disabled类。 可悲的是,不支持disable属性。

<div class="list-group">
  <button type="button" class="list-group-item list-group-item-action active">
    Cras justo odio
  </button>
  <button type="button" class="list-group-item list-group-item-action">Dapibus ac facilisis in</button>
  <button type="button" class="list-group-item list-group-item-action">Morbi leo risus</button>
  <button type="button" class="list-group-item list-group-item-action">Porta ac consectetur ac</button>
  <button type="button" class="list-group-item list-group-item-action" disabled>Vestibulum at eros</button>
</div>

Flush

添加.list-group-flush以删除一些边框和圆角,以在父容器(例如卡片)中以边缘到边缘的方式呈现列表组项目。

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group list-group-flush">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

Horizontal

添加.list-group-horizontal可以将所有断点的列表组项目的布局从垂直更改为水平。 或者,选择响应式变量“ .list-group-horizontal- {sm md lg xl}”,使列表组从该断点的“最小宽度”开始水平。 当前水平列表组不能与刷新列表组合并。

** ProTip:**想要水平时等宽的列表组项目吗? 将“ .flex-fill”添加到每个列表组项。

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
<ul class="list-group list-group-horizontal">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
<ul class="list-group list-group-horizontal-sm">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
<ul class="list-group list-group-horizontal-md">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
<ul class="list-group list-group-horizontal-lg">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
<ul class="list-group list-group-horizontal-xl">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>

上下文类

使用上下文类为具有状态背景和颜色的列表项设置样式。

  • Dapibus ac facilisis in
  • A simple primary list group item
  • A simple secondary list group item
  • A simple success list group item
  • A simple danger list group item
  • A simple warning list group item
  • A simple info list group item
  • A simple light list group item
  • A simple dark list group item
<ul class="list-group">
  <li class="list-group-item">Dapibus ac facilisis in</li>

  
  <li class="list-group-item list-group-item-primary">A simple primary list group item</li>
  <li class="list-group-item list-group-item-secondary">A simple secondary list group item</li>
  <li class="list-group-item list-group-item-success">A simple success list group item</li>
  <li class="list-group-item list-group-item-danger">A simple danger list group item</li>
  <li class="list-group-item list-group-item-warning">A simple warning list group item</li>
  <li class="list-group-item list-group-item-info">A simple info list group item</li>
  <li class="list-group-item list-group-item-light">A simple light list group item</li>
  <li class="list-group-item list-group-item-dark">A simple dark list group item</li>
</ul>

上下文类也可以和.list-group-item-action一起使用。 请注意,此处的悬停样式没有在前面的示例中提供。 还支持.active状态。 应用它以指示上下文列表组项上的活动选择。

<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action">Dapibus ac facilisis in</a>

  
  <a href="#" class="list-group-item list-group-item-action list-group-item-primary">A simple primary list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-secondary">A simple secondary list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-success">A simple success list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-danger">A simple danger list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-warning">A simple warning list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-info">A simple info list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-light">A simple light list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-dark">A simple dark list group item</a>
</div>
Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.

带徽章

在某些 utilities的帮助下,将徽章添加到任何列表组项以显示未读计数,活动等。

  • Cras justo odio 14
  • Dapibus ac facilisis in 2
  • Morbi leo risus 1
<ul class="list-group">
  <li class="list-group-item d-flex justify-content-between align-items-center">
    Cras justo odio
    <span class="badge badge-primary badge-pill">14</span>
  </li>
  <li class="list-group-item d-flex justify-content-between align-items-center">
    Dapibus ac facilisis in
    <span class="badge badge-primary badge-pill">2</span>
  </li>
  <li class="list-group-item d-flex justify-content-between align-items-center">
    Morbi leo risus
    <span class="badge badge-primary badge-pill">1</span>
  </li>
</ul>

自定义内容

借助flexbox utilities,甚至可以为下面的链接列表组添加几乎所有HTML。

<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action active">
    <div class="d-flex w-100 justify-content-between">
      <h5 class="mb-1">List group item heading</h5>
      <small>3 days ago</small>
    </div>
    <p class="mb-1">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
    <small>Donec id elit non mi porta.</small>
  </a>
  <a href="#" class="list-group-item list-group-item-action">
    <div class="d-flex w-100 justify-content-between">
      <h5 class="mb-1">List group item heading</h5>
      <small class="text-muted">3 days ago</small>
    </div>
    <p class="mb-1">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
    <small class="text-muted">Donec id elit non mi porta.</small>
  </a>
  <a href="#" class="list-group-item list-group-item-action">
    <div class="d-flex w-100 justify-content-between">
      <h5 class="mb-1">List group item heading</h5>
      <small class="text-muted">3 days ago</small>
    </div>
    <p class="mb-1">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
    <small class="text-muted">Donec id elit non mi porta.</small>
  </a>
</div>

JavaScript行为

使用选项卡JavaScript插件(单独包含它或通过编译后的“ bootstrap.js”文件包含它)来扩展列表组,以创建本地内容的可选项窗格。

<div class="row">
  <div class="col-4">
    <div class="list-group" id="list-tab" role="tablist">
      <a class="list-group-item list-group-item-action active" id="list-home-list" data-toggle="list" href="#list-home" role="tab" aria-controls="home">Home</a>
      <a class="list-group-item list-group-item-action" id="list-profile-list" data-toggle="list" href="#list-profile" role="tab" aria-controls="profile">Profile</a>
      <a class="list-group-item list-group-item-action" id="list-messages-list" data-toggle="list" href="#list-messages" role="tab" aria-controls="messages">Messages</a>
      <a class="list-group-item list-group-item-action" id="list-settings-list" data-toggle="list" href="#list-settings" role="tab" aria-controls="settings">Settings</a>
    </div>
  </div>
  <div class="col-8">
    <div class="tab-content" id="nav-tabContent">
      <div class="tab-pane fade show active" id="list-home" role="tabpanel" aria-labelledby="list-home-list">...</div>
      <div class="tab-pane fade" id="list-profile" role="tabpanel" aria-labelledby="list-profile-list">...</div>
      <div class="tab-pane fade" id="list-messages" role="tabpanel" aria-labelledby="list-messages-list">...</div>
      <div class="tab-pane fade" id="list-settings" role="tabpanel" aria-labelledby="list-settings-list">...</div>
    </div>
  </div>
</div>

使用数据属性

您只需编写data-toggle =“ list”或元素即可激活列表组导航,而无需编写任何JavaScript。 在.list-group-item上使用这些数据属性。

<!-- List group -->
<div class="list-group" id="myList" role="tablist">
  <a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
  <a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
  <a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
  <a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
</div>

<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel">...</div>
  <div class="tab-pane" id="profile" role="tabpanel">...</div>
  <div class="tab-pane" id="messages" role="tabpanel">...</div>
  <div class="tab-pane" id="settings" role="tabpanel">...</div>
</div>

通过JavaScript

通过JavaScript启用可选项列表项(每个列表项需要单独激活):

$('#myList a').on('click', function (e) {
  e.preventDefault()
  $(this).tab('show')
})

您可以通过以下几种方式激活单个列表项:

$('#myList a[href="#profile"]').tab('show') // Select tab by name
$('#myList a:first-child').tab('show') // Select first tab
$('#myList a:last-child').tab('show') // Select last tab
$('#myList a:nth-child(3)').tab('show') // Select third tab

淡入淡出效果

要使选项卡面板淡入,请向每个.tab-pane中添加.fade。 第一个标签窗格还必须带有.show才能使初始内容可见。

<div class="tab-content">
  <div class="tab-pane fade show active" id="home" role="tabpanel">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel">...</div>
  <div class="tab-pane fade" id="messages" role="tabpanel">...</div>
  <div class="tab-pane fade" id="settings" role="tabpanel">...</div>
</div>

方法(Methods)

$().tab

激活列表项元素和内容容器。 Tab应该具有以DOM中的容器节点为目标的“数据目标”或“ href”。

<div class="list-group" id="myList" role="tablist">
  <a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
  <a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
  <a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
  <a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
</div>

<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel">...</div>
  <div class="tab-pane" id="profile" role="tabpanel">...</div>
  <div class="tab-pane" id="messages" role="tabpanel">...</div>
  <div class="tab-pane" id="settings" role="tabpanel">...</div>
</div>

<script>
  $(function () {
    $('#myList a:last-child').tab('show')
  })
</script>

.tab(‘show’)

选择给定的列表项并显示其关联的窗格。 先前选择的任何其他列表项将变为未选中状态,并且其关联的窗格被隐藏。 在实际显示选项卡窗格之前返回调用者(例如,在“ shown.bs.tab”事件发生之前)。

$('#someListItem').tab('show')

事件(Events)

显示新标签时,事件将按以下顺序触发:

1.hide.bs.tab(在当前活动标签上) 2.show.bs.tab(在待显示的标签上) 3.hidden.bs.tab(在上一个活动选项卡上,与hide.bs.tab事件相同) 4.shown.bs.tab(在刚刚激活的新标签上,与show.bs.tab事件相同)

如果没有标签处于活动状态,则不会触发hide.bs.tabhidden.bs.tab事件。

Event type Description
show.bs.tab This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
shown.bs.tab This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
hide.bs.tab This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use event.target and event.relatedTarget to target the current active tab and the new soon-to-be-active tab, respectively.
hidden.bs.tab This event fires after a new tab is shown (and thus the previous active tab is hidden). Use event.target and event.relatedTarget to target the previous active tab and the new active tab, respectively.
$('a[data-toggle="list"]').on('shown.bs.tab', function (e) {
  e.target // newly activated tab
  e.relatedTarget // previous active tab
})
