javascript - 我的轮播在水平方向上工作得很好，但如何让它在垂直方向上工作呢？

Question

我的网站上有这个轮播来显示产品图片。单击 LI 元素时，该 LI 滚动到 UL 的中心。它在水平方向上工作得很好，但如何使其在垂直方向上工作呢？

我尝试将 Widht 和 width 更改为 Height 和 height，将 Left 和 left 更改为 Top 和 top，将 ScrollLeft 更改为 ScrollTop，但当然它无法正常工作。

  var slidePosition = $(this).position().top;
  var offset = container.scrollTop() + slidePosition - frameWidth + slideWidth / 2;
  container.animate(
    {
      scrollTop: offset
    },
    250
  );
  e.preventDefault();
});

$(".product-preview_mobile-thumbnails-list-inner ul li img").on(
