[英]Bootstrap Navbar (along with topbar) anchor tag navigates content behind the navbar
我在同一頁面中確實有topbar和帶有錨標簽的navbar。 當我單擊定位標記時,定位標記的內容確實會在導航欄后面。 請在下面的代碼中找到:HTML:
<body>

這是我通過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,每當我單擊錨標記時,ID“ whoweare”的內容將從頁面頂部(導航欄后面)開始。 請注意,導航欄的頂部確實有topbar,滾動條上的topbar隱藏了,導航欄位於頂部。
還要注意,我已經添加了索引頁面(第一頁)的代碼,將用於其他頁面(例如:服務,項目等)的topbar和navbar的代碼相同。 請幫助我使導航欄正常運行。
我工作了...
請閱讀這些詳細的說明。
首先 :
使用jQuery,您必須使用HTML中實際存在的選擇器。
在您的腳本中, "#toplinks
, #toplnks
, #toplnked
和#fixedbar
完全不涉及任何內容。
影響是您的腳本根本根本不會觸發。 您觀察到的滾動效果是鏈接單擊的自然默認行為。
第二 :
您有兩個“特殊情況”,其中此腳本不應與其他鏈接做相同的事情。
top-nav
。 href
屬性( href="#"
)。 $(this).attr("href")
以避免腳本錯誤。 我留下了很多解釋性的console.log()
因為我很確定您將使用此菜單向其中添加元素。
您肯定會注意到該腳本在子菜單項上運行了兩次。
這是因為事件正在“冒泡”給它的父事件(“第4節” a
)。
但這沒什么大不了的。
如果嘗試停止這種“起泡”效果,則會破壞菜單上的Bootstrap操作。
因此,只需刪除或注釋掉最后一頁上的所有console.log()
。
;)
這是腳本
這是一個CodePen ,您可以使用它(並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("");
});
