一、按钮组
1、概述
通过按钮组容器把一组按钮放在同一行里。通过与按钮插件联合使用,可以设置为单选框或多选框的样式和行为;
2、基本实例
用.btn 在.btn-group 中包装一系列按钮;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
</body>
</html>
运行结果:
3、按钮工具栏
把一组 <div class="btn-group"> 组合进一个 <div class="btn-toolbar"> 中就可以做成更复杂的组件;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
<div class="btn-group" role="group" aria-label="First group">
<button type="button" class="btn btn-default">1</button>
<button type="button" class="btn btn-default">2</button>
<button type="button" class="btn btn-default">3</button>
<button type="button" class="btn btn-default">4</button>
</div>
<div class="btn-group" role="group" aria-label="Second group">
<button type="button" class="btn btn-default">5</button>
<button type="button" class="btn btn-default">6</button>
<button type="button" class="btn btn-default">7</button>
</div>
<div class="btn-group" role="group" aria-label="Third group">
<button type="button" class="btn btn-default">8</button>
</div>
</div>
</body>
</html>
运行结果:
4、尺寸
只要给 .btn-group 加上 .btn-group-* 类,就省去为按钮组中的每个按钮都赋予尺寸类了,如果包含了多个按钮组时也适用;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="bs-example" data-example-id="button-group-sizing">
<div class="btn-group btn-group-lg" role="group" aria-label="Large button group">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
<br>
<div class="btn-group" role="group" aria-label="Default button group">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
<br>
<div class="btn-group btn-group-sm" role="group" aria-label="Small button group">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
<br>
<div class="btn-group btn-group-xs" role="group" aria-label="Extra-small button group">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
</div>
</body>
</html>
运行结果:
5、嵌套
想要把下拉菜单混合到一系列按钮中,只须把 .btn-group 放入另一个 .btn-group 中;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">1</button>
<button type="button" class="btn btn-default">2</button>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true"
aria-expanded="false">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Dropdown link</a></li>
<li><a href="#">Dropdown link</a></li>
</ul>
</div>
</div>
</body>
</html>
运行结果:
6、垂直排列
让一组按钮垂直堆叠排列显示而不是水平排列,分列式按钮下拉菜单不支持这种方式;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="btn-group-vertical" role="group" aria-label="...">
<button type="button" class="btn btn-default">1</button>
<button type="button" class="btn btn-default">2</button>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true"
aria-expanded="false">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Dropdown link</a></li>
<li><a href="#">Dropdown link</a></li>
</ul>
</div>
</div>
</body>
</html>
运行结果:
7、两端对齐排列的按钮组
让一组按钮拉长为相同的尺寸,填满父元素的宽度。对于按钮组中的按钮式下拉菜单也同样适用;
关于 元素:
只须将一系列 .btn 元素包裹到 .btn-group.btn-group-justified 中即可;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="btn-group btn-group-justified" role="group" aria-label="Justified button group">
<a href="#" class="btn btn-default" role="button">Left</a>
<a href="#" class="btn btn-default" role="button">Middle</a>
<a href="#" class="btn btn-default" role="button">Right</a>
</div>
</body>
</html>
运行结果:
作为按钮的链接:
如果 < a > 元素用作页面内触发按钮的功能,而不是导航到当前页面内的其他文档或部分,那么它们也应该被赋予适当的 role = “ button”;
关于
为了将 <button> 元素用于两端对齐的按钮组中,必须将每个按钮包裹进一个按钮组中you must wrap each button in a button group。大部分的浏览器不能将我们的 CSS 应用到对齐的 <button> 元素上,但是,由于我们支持按钮式下拉菜单,我们可以解决这个问题;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
</head>
<body>
<div class="btn-group btn-group-justified" role="group" aria-label="...">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">Left</button>
</div>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">Middle</button>
</div>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">Right</button>
</div>
</div>
</body>
</html>
运行结果:
二、按钮式下拉菜单
1、说明
把任意一个按钮放入 .btn-group 中,然后加入适当的菜单标签,就可以让按钮作为菜单的触发器了;
2、单按钮下拉菜单
只要改变一些基本的标记,就能把按钮变成下拉菜单的开关;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<!-- Single button -->
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Action <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
</body>
</html>
运行结果:
3、分裂式按钮下拉菜单
相似地,分裂式按钮下拉菜单也需要同样的改变一些标记,但只是多一个分开的按钮;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<!-- Split button -->
<div class="btn-group">
<button type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
</body>
</html>
运行结果:
4、尺寸
按钮式下拉菜单适用所有尺寸的按钮;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<!-- Large button group -->
<div class="btn-group">
<button class="btn btn-default btn-lg dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true"
aria-expanded="false">
Large button <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
</ul>
</div>
<!-- Small button group -->
<div class="btn-group">
<button class="btn btn-default btn-sm dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true"
aria-expanded="false">
Small button <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
</ul>
</div>
<!-- Extra small button group -->
<div class="btn-group">
<button class="btn btn-default btn-xs dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true"
aria-expanded="false">
Extra small button <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
</ul>
</div>
</body>
</html>
运行结果:
5、向上弹出式菜单
给父元素添加 .dropup 类就能使触发的下拉菜单朝上方打开;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<br />
<br />
<br />
<br />
<br />
<br />
<div class="btn-group dropup">
<button type="button" class="btn btn-default">Dropup</button>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
</ul>
</div>
</body>
</html>
运行结果:
三、输入框组
1、说明
通过在文本输入框 <input> 前面、后面或是两边加上文字或按钮,可以实现对表单控件的扩展。为 .input-group 赋予 .input-group-addon 或 .input-group-btn 类,可以给 .form-control 的前面或后面添加额外的元素;
2、基本实例
在输入框的任意一侧添加额外元素或按钮。你还可以在输入框的两侧同时添加额外元素。
我们不支持在输入框的单独一侧添加多个额外元素。(.input-group-addon 或 .input-group-btn)
我们不支持在单个输入框组中添加多个表单控件。
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<!-- <script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script> -->
</head>
<body>
<div class="input-group">
<span class="input-group-addon" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">
</div>
<div class="input-group">
<input type="text" class="form-control" placeholder="Recipient's username" aria-describedby="basic-addon2">
<span class="input-group-addon" id="basic-addon2">@example.com</span>
</div>
<div class="input-group">
<span class="input-group-addon">$</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<span class="input-group-addon">.00</span>
</div>
<label for="basic-url">Your vanity URL</label>
<div class="input-group">
<span class="input-group-addon" id="basic-addon3">https://example.com/users/</span>
<input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
</body>
</html>
运行结果:
3、尺寸
为 .input-group 添加相应的尺寸类,其内部包含的元素将自动调整自身的尺寸。不需要为输入框组中的每个元素重复地添加控制尺寸的类;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<!-- <script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script> -->
</head>
<body>
<div class="input-group input-group-lg">
<span class="input-group-addon" id="sizing-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon1">
</div>
<div class="input-group">
<span class="input-group-addon" id="sizing-addon2">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon2">
</div>
<div class="input-group input-group-sm">
<span class="input-group-addon" id="sizing-addon3">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon3">
</div>
</body>
</html>
运行结果:
4、作为额外元素的多选框和单选框
可以将多选框或单选框作为额外元素添加到输入框组中;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<!-- <script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script> -->
</head>
<body>
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="checkbox" aria-label="...">
</span>
<input type="text" class="form-control" aria-label="...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="radio" aria-label="...">
</span>
<input type="text" class="form-control" aria-label="...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
</div><!-- /.row -->
</body>
</html>
运行结果:
5、作为额外元素的按钮
为输入框组添加按钮需要额外添加一层嵌套,不是 .input-group-addon,而是添加 .input-group-btn 来包裹按钮元素。由于不同浏览器的默认样式无法被统一的重新赋值,所以才需要这样做;
代码演示:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! -->
<title></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果,需要引入js -->
<!-- <script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script> -->
</head>
<body>
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
<input type="text" class="form-control" placeholder="Search for...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
<div class="col-lg-6">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search for...">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
</div><!-- /.row -->
</body>
</html>
运行结果:
6、作为额外元素的按钮式下拉菜单
