我的bootstrap数据间谍有问题。加载页面时，活动链接是第4节中的链接，当我滚动时，链接根本不会更改。这是我的代码，它有什么问题？我确实有css和js用于bootstrap。

<html>
    <head>
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>Website Builder</title>
        <!-- CSS Styles -->
        <link href="{{asset('css/bootstrap.min.css')}}" rel="stylesheet" type="text/css">
        <link href="{{asset('css/style.css')}}" rel="stylesheet" type="text/css">
        <!-- JavaScript Scripts -->
        <script type="text/javascript" src="{!! asset('js/jquery-3.1.1.min.js') !!}"></script>
        <script type="text/javascript" src="{!! asset('js/bootstrap.min.js') !!}"></script>

根据您的示例，没有足够的内容实际滚动浏览。此外，您在div内还有两个未公开的navbar标记，您还需要将position: relative应用于body。

尝试为您的部分添加一些高度，以便自己查看。

工作示例：

＆＃13;
＆＃13; 
body {
  position: relative;
}
section {
  padding: 50px;
  height: 500px;
}
#section1 {
  background: #ffebee;
}
#section2 {
  background: #f44336;
}
#section3 {
  background: #d32f2f;
}
#section41 {
  background: #b71c1c;
}
#section42 {
  background: #ff1744;
}
