我有以下呈现的下拉菜单(来 self 的 Rails 应用程序):

<nav class="navbar navbar-inverse navbar-fixed-top topbar" role="navigation">
  <div class="container-fluid">
    <div class="navbar-header">
      <button class="navbar-toggle" data-target=".navbar-collapse" data-toggle="collapse" type="button">
        <span class="sr-only">Toggle navigation</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span>
      </button>
      <a href="/"></a></div>
    <div class="collapse navbar-collapse navbar-right">
      <ul class="nav navbar-nav">
        <li><a href="/users/edit">Edit account</a></li>
        <li><a data-method="delete" href="/users/sign_out" rel="nofollow">Sign out</a></li>
        <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" href="#">Admin<span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="/users">Users</a></li>
            <li><a href="#"> Another action</a></li>
            <li class="divider"></li>
            <li><a href="#"> Another action2</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </div>
</nav>

显示如下:

partial_menu

看起来不错，但下拉菜单不起作用。我已经让它工作了一段时间，但我不明白为什么这不起作用(下拉列表只是一个指向“#”的链接；即，它不会下拉)。

日志文件什么也没有。我不知道在哪里可以解决这个问题。我该如何解决这个问题？

编辑:从 head 标签添加了 js 这些包括:

最佳答案

您必须通过 JavaScript 调用下拉菜单:

 <script>
        $('.dropdown-toggle').dropdown();
    </script>

将此代码添加到您的脚本中
