我的菜单出现了问题，我找不到原因。当我在响应式视图中测试我的代码时，它首先在从汉堡包图标切换到水平导航栏时正常工作，但是...如果我单击汉堡包图标第一个（一旦下拉菜单并第二次关闭它）和然后调整屏幕大小，我的水平导航菜单消失。导航栏中的错误？
下面是在Codepen中链接的代码。只需进入完整视图并尝试这些步骤，看看您的想法！谢谢！！

为什么你使用的是旧版本的jQuery？ –
我不知道！我不知道我使用的是旧版本。我究竟做错了什么？ – SShine2
我不知道我只是评论它，因为它是旧的，如CDN URL中的版本字符串所示。如果这是一个新项目，考虑到已经有一个V3，你不应该使用jQuery 1。 –
