带有子菜单和平滑滚动的粘性导航 [英] sticky navigation with submenu and smooth scroll

问题描述

我有一个粘滞的导航，但不能将子菜单添加到导航，如果创建子菜单也是如此我想导航保持粘性。那可能吗？
任何帮助将感谢...
这是我目前的HTML

 < nav class = navbar navbar-default navbar-fixed-toprole =navigation> 
< div class =container> 
< div class =row> 
< div class =navbar-header> 
< button class =navbar-toggledata-toggle =collapsedata-target =。navbar-collapse> 
< span class =icon icon-bar>< / span> 
< span class =icon icon-bar>< / span> 
< span class =icon icon-bar>< / span> 
< / button> 
< a href =＃class =navbar-brand>< h3> TEST NAV LOGO< / h3>< / a> 
< / div> 
< div class =collapse navbar-collapse> 
< ul class =nav navbar-nav navbar-right> 
< li>< a href =＃homeclass =smoothScroll> HOME< / a>< / li> 
< li>< a href =＃aboutclass =smoothScroll> ABOUT< / a>< / li> 
< li>< a href =＃teamclass =smoothScroll> TEAM< / a>< / li> 
< / ul> 
< / div> 
< / div> 
< / div>

解决方案

您可以尝试以下代码：

$ b $

  $（document）.scroll（function（）{
 if（$（this）.scrollTop（）> ; 150）{
 $（'。navbar'）。css（'position'，'fixed'）; 
 $（'。navbar'）。css（'top'，'0'）; 
} 
 else {
 $（'。navbar'）.css（'position'，'static'）; 
} 
}）; 
  

以上代码 150 为虚拟值，您可以尝试一个数字根据您的要求。

}

解决方案

You can try below code:

$(document).scroll(function() {
    if ($(this).scrollTop() > 150) {
        $('.navbar').css('position','fixed');
        $('.navbar').css('top','0');
    } 
    else {
        $('.navbar').css('position','static');
    }
});

Here in above code 150 is dummy value you can try a number as per your requirement.
