javascript - 滚动回顶部时向上滚动到上一个 div

Question

滚动回顶部时，我试图回滚到上一部分。我有在最后一个滑块之后连续滚动的解决方案。但是现在我在滚动回顶部时找不到相反的内容。（在拳头滑块后连续滚动顶部）我附上了jsfiddle和codepen片段以供参考

$(document).ready(function () {
  $('.customer-logos').slick({
    vertical: true,
    infinite: false,
    arrows: false,
    dots: true });

});

const slider = $(".customer-logos");


slider.on('wheel', function (e) {

  var slideCount = $(this)[0].slick["slideCount"];
  var currentIndex = $(this).slick("slickCurrentSlide");
  var totalSildeToShow = $(this)[0].slick.options["slidesToShow"];

  if (e.originalEvent.deltaY < 0) {
    e.preventDefault();
    $(this).slick('slickPrev');
  } else {
    if (slideCount - totalSildeToShow === currentIndex)
    return;
    e.preventDefault();
    $(this).slick('slickNext');
  }
});

h2{
  text-align:center;
  padding: 20px;
}
/* Slider */

.slick-slide {
    margin: 0px 20px;
}

.slick-slide img {
    width:500px;
    height:250px;
}
.slick-dots {
    position: absolute;
    bottom: 37% !important;
    display: grid !important;
    width: 0 !important;
    padding: 0;
    margin: 0;
    list-style: none;
    text-align: center;
    top: 15%;
    right: 0;
}
