Bootstrap Navbar(以及topbar)anchor标签可在导航栏后面导航内容

[英]Bootstrap Navbar (along with topbar) anchor tag navigates content behind the navbar

我在同一页面中确实有topbar和带有锚标签的navbar。 当我单击定位标记时,定位标记的内容确实会在导航栏后面。 请在下面的代码中找到:HTML:

<body>
        <!-- Full Body Container -->
        <div id="container">
        <!-- Start Header Section -->
        <header id="header-wrap" class="site-header clearfix">
             <!-- Start Top Bar -->
            <div class="top-bar">
              <div class="container">

      }
      .js .slicknav_menu {
        display: block;
      }
    }

这是我通过stackoverflow帖子搜索的Javascript:

$("#toplinks, #toplnks, #toplnked").on('click','a', function(event){ 
event.preventDefault();
var o =  $( $(this).attr("href") ).offset();   
var sT = o.top - $("#fixedbar").outerHeight(true); 
window.scrollTo(0,sT);
});

因此,每当我单击锚标记时,ID“ whoweare”的内容将从页面顶部(导航栏后面)开始。 请注意,导航栏的顶部确实有topbar,滚动条上的topbar隐藏了,导航栏位于顶部。

还要注意,我已经添加了索引页面(第一页)的代码,将用于其他页面(例如:服务,项目等)的topbar和navbar的代码相同。 请帮助我使导航栏正常运行。

我工作了...
请阅读这些详细的说明。

首先
使用jQuery,您必须使用HTML中实际存在的选择器。
在您的脚本中, "#toplinks#toplnks#toplnked#fixedbar完全不涉及任何内容。

影响是您的脚本根本根本不会触发。 您观察到的滚动效果是链接单击的自然默认行为。

第二
您有两个“特殊情况”,其中此脚本不应与其他链接做相同的事情。

  1. “第1节”需要滚动到窗口位置零才能显示top-nav
    它不应计算偏移量。

  2. “第4节”打开一个子菜单,其中显示“第4-1节”和“第4-2节”。
    由于此“第4节”也是链接,因此您必须删除其无用的href属性( href="#" )。
    然后,在脚本中,必须检查是否已定义$(this).attr("href")以避免脚本错误。

我留下了很多解释性的console.log()因为我很确定您将使用此菜单向其中添加元素。

您肯定会注意到该脚本在子菜单项上运行了两次。
这是因为事件正在“冒泡”给它的父事件(“第4节” a )。
但这没什么大不了的。

如果尝试停止这种“起泡”效果,则会破坏菜单上的Bootstrap操作。
因此,只需删除或注释掉最后一页上的所有console.log()
;)

这是脚本
这是一个CodePen ,您可以使用它(并查看我是如何工作的)。

console.clear()
console.log("READY!");
