Bootstrap 切换按钮不起作用

Question

切换按钮无法显示折叠的元素，我不知道为什么。调整窗口大小时，会显示切换按钮，但按下后不会发生任何情况。这是我第一次使用 Bootstrap，所以我可能犯了一些非常明显和可笑的错误。任何帮助表示赞赏。

Answer 1

您至少有一些问题：请参阅Navbar的文档。

data-toggle="dropdown"应该data-toggle="collapse"

data-target="navHeaderCollapse"应该data-target=".navHeaderCollapse"

解决这两个问题应该允许菜单打开和关闭。您可能希望利用默认结构来避免（或至少注意）将切换按钮包含在类navbar-header以及菜单列表项上的.nav&类中的其他问题。.navbar-nav另外，您container当前没有执行任何操作，它应该围绕导航栏标题/列表项。

工作示例：

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

<div class="boostrap-iso">
  <div class="page">

    <div class="nav navbar-default">
      <div class="container">

        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target=".navHeaderCollapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>

          <a href="#" class="navbar-brand">LOGO</a>
          <a href="#" class="navbar-brand"><span class="glyphicon glyphicon-shopping-cart"></span></a>
        </div>

        <div class="collapse navbar-collapse navHeaderCollapse">
          <ul class="nav navbar-nav">
            <li class="products"><a href="#2">Products</a>
            </li>
            <li class="store"><a href="#3">Store</a>
            </li>
            <li class="about"><a href="#4">About Us</a>
            </li>
            <li class="discover"><a href="#5">Discover</a>
            </li>
            <li class="support"><a href="#6">Support</a>
            </li>
          </ul>
        </div>
