当我在导航栏中将 li 项目更改为链接（使用 hef）时，仅主页、关于和联系人正在显示（这些是没有子菜单的链接）。未显示注册公司和购买公司（这些是带有子菜单的链接）。我在jsfiddle.net/vaanipala/rVNQk/7上的代码。可能是什么问题呢？

仅供参考，如果 li 项目不是链接，则导航栏显示正常。

谢谢你。

你应该使用

$("#submenu1,#submenu2").children("ul").hide();

代替

$("#submenu1,#submenu2").children().hide();
$("#subsubmenu1").children("ul").hide();

隐藏子菜单。这将显示带有子菜单的菜单。

您的链接<a href="a.html">Register Company</a>是子菜单“submenu1”的子菜单，因此您的代码$("#submenu1,#submenu2").children().hide();只是将其隐藏。这就是您看不到这些链接的原因。
