Bootstrap进度条

本章将讲解 Bootstrap 进度条。在本教程中,您将看到如何使用 Bootstrap 创建加载、重定向或动作状态的进度条。

Bootstrap 进度条使用 CSS3 过渡和动画来获得该效果。Internet Explorer 9 及之前的版本和旧版的 Firefox 不支持该特性,Opera 12 不支持动画。

默认的进度条

创建一个基本的进度条的步骤如下:

让我们看看下面的实例:

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 进度条</title>
   <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet">
   <script src="/scripts/jquery.min.js"></script>
   <script src="/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress">
   <div class="progress-bar" role="progressbar" aria-valuenow="60" 
      aria-valuemin="0" aria-valuemax="100" style="width: 40%;">
      <span class="sr-only">40% 完成</span>
   </div>
</div>

</body>
</html>


结果如下所示:

交替的进度条

创建不同样式的进度条的步骤如下:

让我们看看下面的实例:

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 交替的进度条</title>
   <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet">
   <script src="/scripts/jquery.min.js"></script>
   <script src="/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress">
   <div class="progress-bar progress-bar-success" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 90%;">
      <span class="sr-only">90% 完成(成功)</span>
   </div>
</div>
<div class="progress">
   <div class="progress-bar progress-bar-info" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 30%;">
      <span class="sr-only">30% 完成(信息)</span>
   </div>
</div>
<div class="progress">
   <div class="progress-bar progress-bar-warning" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 
      style="width: 20%;">
      <span class="sr-only">20% 完成(警告)</span>
   </div>
</div>
<div class="progress">
   <div class="progress-bar progress-bar-danger" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 10%;">
      <span class="sr-only">10% 完成(危险)</span>
   </div>
</div>

</body>
</html>


结果如下所示:

条纹的进度条

创建一个条纹的进度条的步骤如下:

让我们看看下面的实例:

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 条纹的进度条</title>
   <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet">
   <script src="/scripts/jquery.min.js"></script>
   <script src="/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress progress-striped">
   <div class="progress-bar progress-bar-success" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 90%;">
      <span class="sr-only">90% 完成(成功)</span>
   </div>
</div>
<div class="progress progress-striped">
   <div class="progress-bar progress-bar-info" role="progressbar"
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 30%;">
      <span class="sr-only">30% 完成(信息)</span>
   </div>
</div>
<div class="progress progress-striped">
   <div class="progress-bar progress-bar-warning" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 20%;">
      <span class="sr-only">20% 完成(警告)</span>
   </div>
</div>
<div class="progress progress-striped">
   <div class="progress-bar progress-bar-danger" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 10%;">
      <span class="sr-only">10% 完成(危险)</span>
   </div>
</div>

</body>
</html>


结果如下所示:

动画的进度条

创建一个动画的进度条的步骤如下:

这将会使条纹具有从右向左的运动感。

让我们看看下面的实例:

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 动画的进度条</title>
   <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet">
   <script src="/scripts/jquery.min.js"></script>
   <script src="/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress progress-striped active">
   <div class="progress-bar progress-bar-success" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 
      style="width: 40%;">
      <span class="sr-only">40% 完成</span>
   </div>
</div>

</body>
</html>


结果如下所示:

动画的进度条

堆叠的进度条

您甚至可以堆叠多个进度条。把多个进度条放在相同的 .progress 中即可实现堆叠,如下面的实例所示:

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 堆叠的进度条</title>
   <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet">
   <script src="/scripts/jquery.min.js"></script>
   <script src="/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress">
   <div class="progress-bar progress-bar-success" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 
      style="width: 40%;">
      <span class="sr-only">40% 完成</span>
   </div>
   <div class="progress-bar progress-bar-info" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 30%;">
      <span class="sr-only">30% 完成(信息)</span>
   </div>
   <div class="progress-bar progress-bar-warning" role="progressbar" 
      aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" 	
      style="width: 20%;">
      <span class="sr-only">20% 完成(警告)</span>
   </div>
</div>

</body>
</html>


结果如下所示:
