Question

所以我有这部分代码应该是我的部分工作，目的是制作一个功能索引页面，但是我编写了这段代码，但是找不到菜单键拒绝激活下拉列表的时间点。我在Chrome / Firefox上尝试过这个问题并且两者都有问题，但我找不到确切的问题。

非常感谢指导。

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Ristorante Con Fusion</a>

    <!-- jQuery  -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

    <script src="js/bootstrap.min.js"></script>
