滑动缩略图滑块当前更改缩略图焦点也需要悬停

Question

向所有人问好。你好。我试过用光滑的滑块制作滑块动画。我想更改悬停在缩略图上的主图像。我想问，这可能吗？我在codepen链接(codepan(中添加了我的代码，所以请检查此链接。提前谢谢。尝试这个链接，因为它显示错误，所以我共享我的代码。

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,
}
}
]
});
});

你好，是的，你可以更改悬停在缩略图上的光滑滑块。您可以对光滑的幻灯片调用鼠标悬停函数。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。希望这对你有帮助。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,
settings: {
vertical: false,
slidesToShow: 2,
}
}
]
});
$('.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);

});
});
