Bootstrap 导航栏中的折叠不起作用

Question

我正在尝试使用 bootstrap 创建简单的响应式导航栏。我不知道是什么原因，但折叠导航栏不起作用。已将数据目标分配给可折叠 div 仍然没有任何效果。

<nav class="navbar navbar-inverse" role="navigation">
    <div class="container-fluid">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="navbar-collapse-1">
                <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">Humanity</a>
        </div>

        <div class="collapse navbar-collapse" id="navbar-collapse-1">
            <ul class="nav navbar-nav navbar-right">
                <li>
                    <a href="#Menu 1">Menu 1</a>
                </li>
                <li>
                    <a href="#Menu 2">Menu 2</a>
                </li>
                <li>
                    <a href="#Menu 3">Menu 3</a>
                </li>
            </ul>
        </div>
    </div>
</nav>

您忘记在 data-target.

中添加 #

现在工作正常检查代码段
