单个切换
如需激活单个按钮的切换（即改变按钮的正常状态为按压状态，反之亦然），只需向 button 元素添加 data-toggle="button" 作为其属性即可，如下面实例所示：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>Bootstrap历练实例：按钮(Button)插件单个切换</title>
<meta charset="utf-8" />
<meta name="viewport"content="width=device-width,initial-scale=1.0" />
<link rel="stylesheet"href="bootstrap-3.3.5-dist/css/bootstrap.min.css" />
<script src="jQuery/jquery-2.1.4.js"></script>
<script src="bootstrap-3.3.5-dist/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container"style="padding:20px">
<button type="button"class="btn btn-success"data-toggle="button">单个切换</button>
</div>
</body>
</html>
