Question

我目前正在构建自己的网站并尝试在网站上实现bootstrap scrollspy，但我无法让它工作。这个你能帮我吗。我将从我的测试页面添加代码。这是我取得的进展：

代码：

<!DOCTYPE html>
<html lang="de">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<!-- Die 3 Meta-Tags oben *müssen* zuerst im head stehen; jeglicher  sonstiger head-Inhalt muss *nach* diesen Tags kommen -->
<title>Bootstrap-Basis-Vorlage</title>

<!-- Bootstrap -->
<script     src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">    </script>
<link href="css/bootstrap.min.css" rel="stylesheet">
</head>
<style>
    body{position: relative;}
    #test1{
        height: 1000px;
        background-color: blue;
    }
    #test3{
        height: 1000px;
        background-color: green;
    }
    #test2{
        height: 1000px;
        background-color: red;
    }
</style>
<body data-spy="scroll" data-target="#scrollspytest">
  <nav class="navbar navbar-inverse navbar-fixed-top"  role="navigation">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle" data-toggle="collapse"  data-target=".navbar-collapse">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <div class="navbar-brand">TEST</div>
        </div>
          <div class="collapse navbar-collapse" id="scrollspytest" >
          <ul id="navleiste"class="nav navbar-nav">
            <li><a id="home"  href="#test1">Home</a></li>
            <li><a id="about" href="#test2">About</a></li>
           </ul>
        </div>
      </div>
    </nav>
    <div id="test1"></div>
    <div id="test2"></div>
<script>
    $('body').scrollspy({ target: '#scrollspytest' })
</script>

您应该添加bootstrap.min.js，然后在jquery.min.js之后添加（右）。

以下示例来自W3Schools，正如您所看到的，他们完成了同样的事情。

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css');
 body {
  position: relative;
}
#section1 {
  padding-top: 50px;
  height: 500px;
  color: #fff;
  background-color: #1E88E5;
}
#section2 {
  padding-top: 50px;
  height: 500px;
  color: #fff;
  background-color: #673ab7;
}
#section3 {
  padding-top: 50px;
  height: 500px;
  color: #fff;
  background-color: #ff9800;
}
#section41 {
  padding-top: 50px;
  height: 500px;
  color: #fff;
  background-color: #00bcd4;
}
#section42 {
  padding-top: 50px;
  height: 500px;
  color: #fff;
  background-color: #009688;
}

<body data-spy="scroll" data-target=".navbar" data-offset="50">
