我的轮播可以完美地水平工作，但如何让它垂直工作?

Question

我的网站上有这个轮播来显示产品图片。当单击 LI 元素时，该 LI 会滚动到边缘的 UL 中心。它在水平方向上工作得很好，但是我如何让它在垂直方向上工作呢？

我试图将 Widht 和宽度更改为高度和高度，将左和左更改为顶部和顶部，将左滚动更改为滚动顶部，但当然它不能正常工作。

我已经通过一些编辑更新了小提琴。希望这有帮助！你应该能够从这里开始。

.JS

$(".product-preview_mobile-thumbnails-list-inner ul li").on("click", function(e) {
var container = $(this).parent().parent();
var slideWidth = $(this).height();
var frameWidth = container.height() / 2;
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(
"click",
function() {
$("img.current-mobile-thumbnail").removeClass("current-mobile-thumbnail");
$(this).addClass("current-mobile-thumbnail");
}
