Bootstrap学习 - 组件


下拉菜单

注意:需要先引入jQuery.js再引入bootstrap.js(依赖前者)

<div class="dropdown pull-right">  //默认就是dropdown可不写,dropup向上弹出,小三角也会自动变为向上
  <button class="dropdown-toggle btn btn-default " type="button" data-toggle="dropdown">
    Dropdown<span class="caret"></span>
  </button>
  <ul class="dropdown-menu dropdown-menu-right"">
    <li class="dropdown-header">Language</li>
    <li><a role="menuitem">Python</a></li>
    <li class="disabled"><a role="menuitem">Java</a></li>
    <li><a role="menuitem">PHP</a></li>
    <li class="divider"></li>
    <li><a>JavaScript</a></li>
  </ul>
</div>

按钮组

以CDN的方式引入Bootstrap:<link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css">
<div class="btn-group">    //btn-group-vertical  垂直排列    // btn-group-justified 水平铺满容器
<button type="button" class="btn btn-success">按钮1</button>
<button type="button" class="btn btn-primary">按钮2</button>
<button type="button" class="btn btn-danger">按钮3</button>
</div>
效果: Bootstrap学习 - 组件         不加btn-group效果: Bootstrap学习 - 组件

可以利用这一功能做一些按钮工具栏,像这样的
Bootstrap学习 - 组件 还可以在btn-group中嵌套下拉菜单
<div class="btn-group">
   <button type="button" class="btn btn-default">1</button>
   <button type="button" class="btn btn-default">2</button>
   <div class="btn-group">
     <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">3 <span class="caret"></span></button>
     <ul class="dropdown-menu">
      <li><a>A</a></li>
      <li><a>B</a></li>
     </ul>
   </div>
</div>

 

分裂式下拉菜单

<div class="container">
  <div class="btn-group">
    <button type="button" class="btn btn-info">分裂式</button> //就是把普通的下拉菜单和前一个按钮放到一个btn-group里了
    <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown"><span class="caret"></span></button>
    <ul class="dropdown-menu">
      <li><a>A</a></li>
      <li><a>B</a></li>
    </ul>
    <button type="button" class="btn btn-warning">按钮2</button>
    <button type="button" class="btn btn-success">按钮3</button>
  </div>

输入框组

<div class="input-group">
  <span class="input-group-addon">❤</span> //input-group-btn
