Bootstrap 按钮组_菜鸟教程

Bootstrap 按钮组

按钮组允许多个按钮被堆叠在同一行上。当你想要把按钮对齐在一起时，这就显得非常有用。您可以通过 Bootstrap 按钮（Button）插件添加可选的 JavaScript 单选框和复选框样式行为。

下面的表格总结了 Bootstrap 提供的使用按钮组的一些重要的 class：

Class	描述	代码示例
.btn-group	该 class 用于形成基本的按钮组。在 .btn-group 中放置一系列带有 class .btn 的按钮。	<div class="btn-group"> <button type="button" class="btn btn-default">Button1</button> <button type="button" class="btn btn-default">Button2</button> </div>
.btn-toolbar	该 class 有助于把几组 <div class="btn-group"> 结合到一个 <div class="btn-toolbar"> 中，一般获得更复杂的组件。	<div class="btn-toolbar" role="toolbar"> <div class="btn-group">...</div> <div class="btn-group">...</div> </div>
.btn-group-lg, .btn-group-sm, .btn-group-xs	这些 class 可应用到整个按钮组的大小调整，而不需要对每个按钮进行大小调整。	<div class="btn-group btn-group-lg">...</div> <div class="btn-group btn-group-sm">...</div> <div class="btn-group btn-group-xs">...</div>
.btn-group-vertical	该 class 让一组按钮垂直堆叠显示，而不是水平堆叠显示。	<div class="btn-group-vertical"> ... </div>

基本的按钮组

下面的实例演示了上面表格中讨论到的 class .btn-group 的使用：

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 基本的按钮组</title>
   <link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
   <script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
   <script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="btn-group">
  <button type="button" class="btn btn-default">按钮 1</button>
  <button type="button" class="btn btn-default">按钮 2</button>
  <button type="button" class="btn btn-default">按钮 3</button>
</div>

</body>
</html>

结果如下所示：

按钮工具栏

下面的实例演示了上面表格中讨论到的 class .btn-toolbar 的使用：

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 按钮工具栏</title>
   <link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
   <script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
   <script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="btn-toolbar" role="toolbar">
  <div class="btn-group">
  <button type="button" class="btn btn-default">按钮 1</button>
  <button type="button" class="btn btn-default">按钮 2</button>
  <button type="button" class="btn btn-default">按钮 3</button>
 </div>
  <div class="btn-group">
  <button type="button" class="btn btn-default">按钮 4</button>
  <button type="button" class="btn btn-default">按钮 5</button>
  <button type="button" class="btn btn-default">按钮 6</button>
  </div>
  <div class="btn-group">
  <button type="button" class="btn btn-default">按钮 7</button>
  <button type="button" class="btn btn-default">按钮 8</button>
  <button type="button" class="btn btn-default">按钮 9</button>
  </div>
</div>

</body>
</html>

结果如下所示：

按钮的大小

下面的实例演示了上面表格中讨论到的 class .btn-group-* 的使用：

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 按钮组的大小</title>
   <link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
   <script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
   <script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="btn-group btn-group-lg">
  <button type="button" class="btn btn-default">按钮 1</button>
  <button type="button" class="btn btn-default">按钮 2</button>
  <button type="button" class="btn btn-default">按钮 3</button>
 </div>
  <div class="btn-group btn-group-sm">
  <button type="button" class="btn btn-default">按钮 4</button>
  <button type="button" class="btn btn-default">按钮 5</button>
  <button type="button" class="btn btn-default">按钮 6</button>
</div>
  <div class="btn-group btn-group-xs">
  <button type="button" class="btn btn-default">按钮 7</button>
  <button type="button" class="btn btn-default">按钮 8</button>
  <button type="button" class="btn btn-default">按钮 9</button>
</div>

</body>
</html>

结果如下所示：

嵌套

您可以在一个按钮组内嵌套另一个按钮组，即，在一个 .btn-group 内嵌套另一个 .btn-group 。当您想让下拉菜单与一系列按钮组合使用时，就会用到这个。

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 嵌套的按钮组</title>
   <link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
   <script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
   <script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="btn-group">
  <button type="button" class="btn btn-default">按钮 1</button>
  <button type="button" class="btn btn-default">按钮 2</button>

  <div class="btn-group">
    <button type="button" class="btn btn-default dropdown-toggle"        data-toggle="dropdown">
      下列
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      <li><a href="#">下拉链接 1</a></li>
      <li><a href="#">下拉链接 2</a></li>
    </ul>
  </div>
</div>

</body>
</html>

结果如下所示：

垂直的按钮组

下面的实例演示了上面表格中讨论到的 class .btn-group-vertical 的使用：

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 垂直的按钮组</title>
   <link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
   <script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
   <script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="btn-group-vertical">
  <button type="button" class="btn btn-default">按钮 1</button>
  <button type="button" class="btn btn-default">按钮 2</button>

  <div class="btn-group-vertical">
    <button type="button" class="btn btn-default dropdown-toggle"        data-toggle="dropdown">
      下拉
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      <li><a href="#">下拉链接 1</a></li>
      <li><a href="#">下拉链接 2</a></li>
    </ul>
  </div>
</div>

</body>
</html>
