javascript - 使用 div 更改 Active Slick Carousel

Question

我们正在使用 slick carousel这样我们就有了<div class='item__wrapper'>一次只显示一张幻灯片。下面是三个items单击 item 的位置，光滑的旋转木马应该更新。

问题

1. 使用 item__boxes 时作为slick旋转木马，我们所有的样式都乱七八糟，所以我们不能做$('.item__boxes).slick({});
2. 点击第一个、第二个或第三个时 item在 item__boxes , item__wrapper始终设置为 slide 3

问题

• 我们如何设置 item__boxes这样就可以点击那个 item它符合我们的目标吗？例如，点击第二个 item在 item__boxes设置 item__wrapper到第二张幻灯片。

目标/预期结果:

1. 点击第一个 item , 将第一张幻灯片设置为 item__wrapper 中的事件幻灯片
2. 点击第二个 item , 将第二张幻灯片设置为 item__wrapper 中的事件幻灯片
3. 点击第三个 item , 将第三张幻灯片设置为 item__wrapper 中的事件幻灯片
4. 完成所有目标 1-3不做$('.item__boxes).slick({});

代码:

$('.item__wrapper').slick({
	
          infinite: true,
          speed: 1500,
          dots: false,
          prevArrow: false,
          nextArrow: false
});

$('.item__boxes').on('click', function() {
	
	var slickIndex = $(this).attr('data-slick-index');
	$('.item__wrapper').slick('slickGoTo', slickIndex);
});

.filter {
  width: 100%;
  height: 100%;
  padding: 45px;
