Question

我正在研究Bootswatch和Angular2的一个主题。这可能之前已经回答过，但我找不到任何参考。我有一个下拉列表，它不是基于按钮而是基于链接。我知道它有选项，但它总是崩溃，即使我将鼠标悬停在它上面。有什么我想念的东西。这是来自html文件的片段。我是否需要某种切换开关来打开/关闭下拉列表？

<li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
      <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
        <li class="divider"></li>
        <li><a href="#">One more separated link</a></li>
      </ul>
    </li>

<强>你好。请务必将这些脚本标记导入index.html;

<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js" integrity="sha384-A7FZj7v+d/sdmMqp/nOQwliLvUsJfDHW+k9Omg/a/EheAdgtzNs3hpfag6Ed950n" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.4.0/js/tether.min.js" integrity="sha384-DztdAPBWPRXSA/3eYEEUWrWCy7G5KFbe8fFjk5JAIxUYHKkDx6Qin1DkWx51bBrb" crossorigin="anonymous"></script>

您的index.html应如下所示：

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <title>Angular On Rails</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">

导航栏可能会格式化有点奇怪。

要解决此问题： <nav class="navbar navbar-default navbar-inverse">

navbar-default来自开始导航标记

并替换为： <nav class="navbar navbar-toggleable-md navbar-inverse">

navbar-toggleable-md

我希望这会有所帮助。祝你好运。 -Steve
