Question

我正在尝试在我的网站上进行侧面导航，以在其四个按钮中添加“活动”类，但我似乎无法使其正常运行。

我已经成功地将航路点添加到代码中，但是它们似乎总是有些偏离，并且需要用户额外滚动一点以激活航路点。我也尝试遵循文档中的{offset}规则，但是没有任何面纱。他们要么从头开始停止正常工作，要么从头到尾停止工作。

为了使sidenav正常工作，我将页面分为几列，如下面的CSS所示。请随意提供有关代码的见解，因为这是一项学习练习，我知道目前我的代码非常脏（尤其是Javascript）

侧面导航：

<div class="sidebar verticalized" id="sidebar-verticalized">
  <ul id="sidenav" class="side nav-fixed hide-on-med-and-down">
    <li class="side-link">
      <a class="side-link-first link1" onclick="clickOne()" href="#">01</a>
    </li>
    <li class="side-link">
      <a href="#portfolio" onclick="clickTwo()" class="link2">02</a>
    </li>
    <li class="side-link">
      <a href="#what-we-do" onclick="clickThree()" class="link3">03</a>
    </li>
    <li class="side-link">
      <a href="#contact" onclick="clickFour()" class="link4">04</a>
    </li>
  </ul>
</div>

CSS：

html {
overflow: scroll;
overflow-x: hidden;
}
::-webkit-scrollbar {
width: 0px;  /* remove scrollbar space */
background: transparent;  /* optional: just make scrollbar invisible */
}

.page{
display: grid;
grid-template-columns: 300px auto;
}
.sidebar{
position:fixed;
width:300px;
}
.main{
grid-column-start:2;
}
.verticalized {
margin: 0px;
padding:0px;
float: left;
top: 50%;
transform: translateY(-50%) translateX(-50%);
left:9%;
}

我的JS烂摊子（每个部分都在下面声明）：

var $section1 = $('.header');
var $section2 = $('.portfolio');
var $section3 = $('.what-we-do');
var $section4 = $('.contact');
var $link1 = $('.link1');
var $link2 = $('.link2');
var $link3 = $('.link3');
var $link4 = $('.link4');

$section1.waypoint(function (){
  $link1.addClass('active');
  $link2.removeClass('active');
  $link3.removeClass('active');
  $link4.removeClass('active');
});

$section2.waypoint(function(){
  $link1.removeClass('active');
  $link2.addClass('active');
  $link3.removeClass('active');
  $link4.removeClass('active');
});

$section3.waypoint(function(){
  $link1.removeClass('active');
  $link2.removeClass('active');
  $link3.addClass('active');
  $link4.removeClass('active');
});

$section4.waypoint(function(){
  $link1.removeClass('active');
  $link2.removeClass('active');
  $link3.removeClass('active');
  $link4.addClass('active');
});

到目前为止，我已经尝试过：

偏移：视图底部（部分有时太大，因此仍保留旧的活动元素）

偏移量：+/- x％（这从一端解决了问题，但从另一端没有解决：我可能在链接上从1变为4，并且可以正常工作，但从4到1断开了，反之亦然）

欢迎任何意见和提示。我正在尝试模仿每个部分的活动项目的引导导航栏行为。
