[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:

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
和#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。
top-nav
。 href
属性( href="#"
)。 $(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!");
$(".navbar-nav li").on('click','a', function(event){
event.preventDefault();
// Which link was clicked?
console.log($(this).attr("href"));
// Section 1 case:
if( $(this).attr("href")=="#section1" ){
$("body").scrollTop(0);
console.log("Window simply has to scroll to position: 0");
}
// Section 4 case (Or any link which triggers a sub-menu)
if(typeof($(this).attr("href"))=="undefined"){
console.log("This link shall NOT trigger a scroll.");
}
// All the other cases.
if(typeof($(this).attr("href"))!="undefined" && $(this).attr("href")!="#section1"){
var o = $( $(this).attr("href") ).offset();
var sT = o.top - $(".navbar").outerHeight(true);
window.scrollTo(0,sT);
console.log("Section offset is: "+o.top);
console.log("Nav bar height is: "+$(".navbar").outerHeight(true));
console.log("Window has to scroll to position: "+sT);
}
// Just an empty console line for clarity.
console.log("");
});
