Bootstrap下拉菜单对我不起作用。正如你在那里看到的那样，我做得很正确：

<div class="container">
<ul class="menu">
<li class="current"><span style="color: #bde2e1;">Home</li>
<li class="dropdown"><a class="dropdown-toggle" href="#">Servers</a>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    <li class="hovering"><a href="#">Portfolio</a></li>
<li class="hovering"><a href="#">Releases</a></li>
<li class="hovering"><a href="#">Contact</a></li>

</li>

<li class="hovering"><a href="#">Portfolio</a></li>
<li class="hovering"><a href="#">Releases</a></li>
<li class="hovering"><a href="#">Contact</a></li>
</ul>

Bootstrap是一个现成的框架，具有网格系统、行、现成的js菜单等功能。

它的工作原理有一个解释：

是的，我的src正确链接到JS文件。

您在html中缺少body。

将脚本放在页面底部或准备好后：

<script type="text/javascript">
$(function(){
    $('.dropdown-toggle').dropdown();
});
</script>

编辑：

使用较新版本的jquery。

<header>
    <div class="navbar navbar-static header">
        <div class="navbar-inner container">
            <ul class="nav" role="navigation">
               <li class="brand"><span style="color: #bde2e1;">Home</span></li>
               <li class="dropdown">
                   <a class="dropdown-toggle" id="drop4" role="button" data-toggle="dropdown" href="#">Dropdown <b class="caret"></b></a>
                   <ul id="menu1" class="dropdown-menu" role="menu" aria-labelledby="drop4">
                       <li><a tabindex="-1" href="#">Action</a></li>
                       <li><a tabindex="-1" href="#">Another action</a></li>
                       <li><a tabindex="-1" href="#">Something else here</a></li>
                       <li class="divider"></li>
                       <li><a tabindex="-1" href="#">Separated link</a></li>
                   </ul>
               </li>
               <li class="hovering"><a href="#">Portfolio</a></li>

           </ul>
           <div id="logo"><a href="#"><img src="img/logo.png" /></a></div>
       </div>
    </div>
</header>
<script type="text/javascript">
