Javascript 顶部固定导航栏中的链接没有响应
我正在为我的单个页面使用一个小小的Javascript导航栏。我所有的文本链接都可以正常工作,但右侧的出站社交媒体链接没有响应(除非您再次单击并从那里打开)。现在,我对JQuery和Javascript几乎一无所知……我可以理解它以及它是如何工作的,但当遇到错误时,我无法理解它。谢谢你的帮助!:) 这是我的CSS:Javascript 顶部固定导航栏中的链接没有响应,javascript,jquery,html,css,navigation,Javascript,Jquery,Html,Css,Navigation,我正在为我的单个页面使用一个小小的Javascript导航栏。我所有的文本链接都可以正常工作,但右侧的出站社交媒体链接没有响应(除非您再次单击并从那里打开)。现在,我对JQuery和Javascript几乎一无所知……我可以理解它以及它是如何工作的,但当遇到错误时,我无法理解它。谢谢你的帮助!:) 这是我的CSS: .single-page-nav { background: rgb(255, 255, 255); background: rgba(255, 255, 255,

问题在于,javascript大幅更改了单页导航
容器内的默认链接行为。它还将此javascript功能应用于您的外部链接,您不希望为了使它们正常工作而拥有这些链接
