Question

出于某种原因，我的导航栏中的下拉菜单无法正常工作。下拉按钮在那里，但是没有下拉，因此下拉触发部分可能有问题。我已经尝试了一切，但无法解决，感谢您的帮助。以下是实现文档的链接：https://materializecss.com/navbar.html

Answer 1

$(document)是jQuery选择器，您没有包括jQuery的路径。我将以下行添加到您的代码中，并且下拉列表工作正常：<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>。您可以了解有关此here的更多信息。

代码行应包含在以下内容之前：

<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js"></script>

代码无法正常工作的原因是Materialize CSS使用jQuery方法。

物化导航栏下拉菜单不起作用
