问题背景:
我正在 ASP.NET MVC 项目中使用 Twitter Bootstrap 3 开发一个单页网站。
问题:
我目前正在尝试实现“平滑滚动”，该滚动应该通过从导航栏下拉列表中单击来滚动到相关的 div。当从导航栏下拉菜单中单击某个部分时，它会“跳转”到 div 而不是滚动。
代码:
以下是我的“_Layout.cshtml”标记，提供了导航栏和页脚。滚动的 JavaScript 显示在脚本标签之间:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>@ViewBag.Title - My ASP.NET Application</title>
@Styles.Render("~/Content/css")
@Scripts.Render("~/bundles/modernizr")
<script>
$('#nav .navbar-nav li>a').click(function () {
var link = $(this).attr('href');
var offSet = 30;
var targetOffset = $(link).offset().top - offSet;
$('html,body').animate({ scrollTop: targetOffset }, 7000);
});
</script>
</head>
<body>
<div class="navbar navbar-fixed-top">
<nav class="navbar navbar-default" role="navigation" id="nav">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">

屏幕截图:
以下屏幕截图显示，当单击导航栏选项时，页面会转到正确的 div，但不会滚动。任何解决此问题的帮助都会很棒。
最佳答案
经过更多研究并使用这个很好的例子:http://alijafarian.com/responsive-page-scrolling-with-jquery-and-bootstrap/我设法生成了以下完美运行的解决方案。
<script>
$(document).ready(function() {
$('#nav .navbar-nav li>a').on('click', function(event){
event.preventDefault();
var sectionID = $(this).attr("href");
scrollToID(sectionID, 750);
});
function scrollToID(id, speed)
{
var offSet = 70;
var targetOffset = $(id).offset().top - offSet;
$('html,body').animate({scrollTop:targetOffset}, speed);
}
});
</script>
