可能我忽略了一件非常简单的事情，但我似乎找不到使用 jquery mouseenter 隐藏#panel div 的方法。无论我尝试什么，它都无济于事。我已多次检查所有代码，并加载了所有必需的库。我想要实现的是，如果用户在 drop 类和任何

  • 该类中的标签，然后#panel 保持隐藏。我只想在用户完全离开菜单时显示#panel。有人可以指出我的错误。谢谢

    使用

     $("#menu .drop li")

    仅适用于父级为“drop”的 li 元素，而父级的父级为“menu”。而且我在您的 html 代码中没有看到类似的内容。使用你的选择器并不意味着“要么.drop” li，而是“li在里面.drop”
