我的 bootstrap 导航栏代码有什么问题？

Question

我的 bootstrap 导航栏工作得很好，但如果我在开发人员工具中切换到 phone 视图并单击展开按钮，它就不会展开。

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Storyfactory</a>
  <button class="navbar-toggler collapsed bg-primary" type="button" data-toggle="#hanshuber" data-target="#navbar" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="hanshuber">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item">
        <a class="nav-link" href="/">Home</a>
      </li>
    </ul>
    <a href="/user/2" class="mr-3"><i class="fas fa-user"></i></a>
    <a href="http://localhost:8000/logout"><i class="fas fa-sign-out-alt"></i></a>
    </div>
</nav>

Answer 1

您的 toggle 和 target 数据属性不正确。

data-toggle="collapse" data-target="#hanshuber"

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" rel="stylesheet"/>

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Storyfactory</a>
  <button class="navbar-toggler collapsed bg-primary" type="button" data-toggle="collapse" data-target="#hanshuber" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="hanshuber">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item">
        <a class="nav-link" href="/">Home</a>
      </li>
    </ul>
    <a href="/user/2" class="mr-3"><i class="fas fa-user"></i></a>
    <a href="#"><i class="fas fa-sign-out-alt"></i></a>
    </div>
</nav>
