＆＃13; 您好我正在为我的网站使用fullpage.js模板。我正在使用现有的菜单条形码fullpage.js模板。我想更改特定部分的标题背景。当我滚动到第三部分时，我想更改为将标题背景更改为白色。

试试这个：

var top1 = $('#section1').offset().top;
var top2 = $('#section2').offset().top;
var top3 = $('#section3').offset().top;
var top4 = $('#section4').offset().top;
var top5 = $('#section5').offset().top;

$(document).scroll(function() {
  var scrollPos = $(document).scrollTop();
  if (scrollPos >= top1 && scrollPos < top2) {
    $('#change').css('background-color', '#f00');
  } else if (scrollPos >= top2 && scrollPos < top3) {
    $('#change').css('background-color', '#0f0');
  } else if (scrollPos >= top3 && scrollPos < top4) {
    $('#change').css('background-color', '#00f');
  } else if (scrollPos >= top4 && scrollPos < top5) {
    $('#change').css('background-color', '#000');
  }else if (scrollPos >= top5) {
    $('#change').css('background-color', '#ff0000');
  }
});

body {
  margin: 0;
  padding-top: 30px
}
header {
  position: fixed;
  top: 0;
  width: 100%;
  height: 30px;
  background-color: #000;
}
ul{
  list-style-type:none;
  padding: 0px;
  margin: 0px;
}
ul li{
  display: inline-block;
  padding: 5px;
}
section {
  height: 500px;
  background-color: #aaa;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<header id="change">
  <div class="container">
    <ul>
        <li><a href="index.html">Home</a></li>
        <li><a href="about.html">About Us</a></li>
        <li><a href="whatwedo.html">What We Do</a></li>
        <li><a href="getinvolved.html">Get Involved</a></li>
        <li><a href="contactus.html">Contact Us</a></li>
    </ul>
  </div>
</header>

<section id="section1">Content</section>
<section id="section2">Content</section>
<section id="section3">Content</section>
<section id="section4">Content</section>
<section id="section5">Content</section>
