我想知道是否有人知道为什么我的汉堡按钮不会下拉到我的导航栏上？我不确定我是否没有上传正确的 JS 文件或什么？我的 JS 文件中也有一个 scrollspy 函数。

【解决方案1】：

您在<div class="collapse navbar-collapse"> 上缺少id="navbarCollapse"

这是由<button> 的data-target="#navbarCollapse" 引用的

<div class="navbar-spy">
    <div class="collapse navbar-collapse" id="navbarCollapse">
        <ul class = "nav navbar-nav pull-right">
          {% if user.is_authenticated %}
            <li><a href ="{% url 'posts:create' %}" class="btn btn-simple">Post</a></li>
            <li><a href ="{% url 'groups:all' %}" class="btn btn-simple">Groups</a></li>
            <li><a href ="{% url 'groups:create' %}" class="btn btn-simple">Create Group</a></li>
            <li><a href ="{% url 'accounts:logout' %}" class="btn btn-simple">Logout</a></li>
          {% else %}
            <li><a href ="{% url 'groups:all' %}" class="btn btn-simple">Groups</a></li>
            <li><a href ="{% url 'accounts:login' %}" class="btn btn-simple">Login</a></li>
            <li><a href ="{% url 'accounts:signup' %}" class="btn btn-simple">Signup</a></li>
          {% endif %}
        </ul>
    </div>
</div>
