光滑的缩略图滑块目前在缩略图焦点需要悬停时发生变化

Question

大家好。再会。我试过使用光滑的滑块来制作滑块动画。我想在其缩略图悬停时更改主图像。请问这可能吗？我在 codepen link (codepan) 中添加了我的代码，因此请检查此 link。提前致谢。试试这个 link 因为它显示错误所以我分享我的代码。

jQuery(document).ready(function($) {
      $('.slider-for').slick({
          slidesToShow: 1,
          slidesToScroll: 1,
          arrows: false,
          fade: true,
          asNavFor: '.slider-nav'
      });
      $('.slider-nav').slick({
          slidesToShow: 6,
          slidesToScroll: 1,

          asNavFor: '.slider-for',
          dots: false,
          focusOnSelect: true,
          responsive: [{
                  breakpoint: 992,
                  settings: {
                      vertical: false,
                  }
              },
              {
                  breakpoint: 768,
                  settings: {
                      vertical: false,
                  }
              },
              {
                  breakpoint: 580,
                  settings: {
                      vertical: false,
                      slidesToShow: 3,
                  }
              },
              {
                  breakpoint: 380,
                  settings: {
                      vertical: false,
                      slidesToShow: 2,
                  }
              }
          ]
      });
  });

美好的一天，是的，您可以更改悬停在缩略图上的光滑滑块。您可以为 slick-slide 调用鼠标悬停功能。创建一个条件，如果鼠标悬停在光滑的导航（缩略图）上，则更改当前活动的目标。希望这会帮助你。我编辑了你的代码。

jQuery(document).ready(function($) {
      $('.slider-for').slick({
          slidesToShow: 1,
          slidesToScroll: 1,
          arrows: false,
          fade: true,
          asNavFor: '.slider-nav'
      });
      //set active class to first slide
$('.slider-nav .slick-slide').eq(0).addClass('slick-active');
      $('.slider-nav').slick({
          slidesToShow: 6,
          slidesToScroll: 1,

          asNavFor: '.slider-for',
          dots: false,
          focusOnSelect: true,
          responsive: [{
                  breakpoint: 992,
                  settings: {
                      vertical: false,
                  }
              },
              {
                  breakpoint: 768,
                  settings: {
                      vertical: false,
                  }
              },
              {
                  breakpoint: 580,
                  settings: {
                      vertical: false,
                      slidesToShow: 3,
                  }
              },
              {
                  breakpoint: 380,

              }
          ]
      });
      $('.slider-nav').on('mouseover', '.slick-slide', function (e) {
        var $currTarget = $(e.currentTarget), 
        index = $currTarget.data('slick-index'),
        slickObj = $('.slider-for').slick('getSlick');
    
    slickObj.slickGoTo(index);
