javascript - Slick Slider 多个 slider 保持事件位置

Question

我在一页上有多个 Slick Sliders。每个 slider 都有一个缩略图 Nav。问题是 slider 使用以前的当前位置而不是从第一个缩略图开始。

我猜我需要一种动态添加 id 的方法，这样它们就不会相互影响。 (我的 JS 知识很基础)

  $('.slider-products').slick({
   slidesToShow: 1,
   slidesToScroll: 1,
   arrows: false,
   fade: true,
   asNavFor: '.slider-nav'
  });


  var windowWidth = $(window).width();
  if(windowWidth <= 800) {
    $('.slider-nav').slick({
    vertical: false,
    slidesToShow: 4,
    slidesToScroll: 1,
    asNavFor: '.slider-products',
    arrow: false,
    focusOnSelect: true
   });
 } 
 else {
   $('.slider-nav').slick({
   vertical: true,
   slidesToShow: 3,
   slidesToScroll: 1,
   asNavFor: '.slider-products',
   focusOnSelect: true
 });
}

Answer 1

1. 使用the .each method绕过所有 slider 。
2. 通过 the .addClass method 为每对 slider 添加一个编号类.
3. 使用the responsive option根据屏幕宽度更改设置。

var numSlick = 0;
$('.slider-products').each( function() {
  numSlick++;
  $(this).addClass( 'slider-' + numSlick ).slick({
    arrows: false,
    asNavFor: '.slider-nav.slider-' + numSlick,
    fade: true,
    slidesToScroll: 1,
    slidesToShow: 1,
  });
});

numSlick = 0;
$('.slider-nav').each( function() {
  numSlick++;
  $(this).addClass( 'slider-' + numSlick ).slick({
    arrow: false,
    asNavFor: '.slider-products.slider-' + numSlick,
    focusOnSelect: true,
    slidesToScroll: 1,
    slidesToShow: 4,
    responsive: [
      {
        breakpoint: 800,
        settings: {
          slidesToShow: 3,
        }
      }
    ]
  });
});

.slick-arrow {
  display: none !important; /* `arrows: false;` is not enough to prevent horizontal scrolling */
}
.slick-slide {
  background: #c69;
  border: 2px solid #fff;
  color: #fff;
  font-size: 36px;
  font-weight: bold;
  outline: none; /* prevent the appearance of a tiny gray contour */
  padding: 18px 0;
  text-align: center;
}
.slider:nth-of-type(n+3) .slick-slide { background: #9c6; }
.slider:nth-of-type(n+5) .slick-slide { background: #69c; }
.slider-nav {
  margin-bottom: 12px;
}
.slider-nav .slick-slide:hover {
  cursor: pointer;
  opacity: .7;
}
