使用CSS Webkit和Slick的背景JavaScript动画

如何解决使用CSS Webkit和Slick的背景JavaScript动画

我有一个滑块，可根据当前图像更改背景。问题是背景之间的过渡不存在。我不想使用“过渡”适当性，因为它没有提供我想要的确切动画。

Codepen：https://codepen.io/jinzagon/pen/LYNGNEZ

用于更改背景的脚本：

$(function(){


var imgurl = {
    "image1" : "https://wallpaperaccess.com/full/184795.jpg","image2" : "https://images2.alphacoders.com/774/774269.jpg","image3" : "https://wallpapercave.com/wp/wp2020010.jpg",};


 
$('.slider').slick({
    dots: true,infinite: true,speed: 800,slidesToShow: 1,adaptiveHeight: true,autoplay: true,autoplaySpeed: 8000,slidesToScroll: 1,arrows: false,});
  
changeBg(imgurl)
$('#slider').on('afterChange',".slider",function(event,slick,currentSlide,nextSlide){
    changeBg(imgurl)
});  

function changeBg(imgurl) {
    $("body").css("background-image","url(" + imgurl[$(".slick-track div.slick-slide.slick-active").attr("class").split(" ")[0]] + ")");

}
});

所需动画的脚本：

.fade-in-right {
            -webkit-animation: fade-in-right 0.6s cubic-bezier(0.390,0.575,0.565,1.000) both;
                    animation: fade-in-right 0.6s cubic-bezier(0.390,1.000) both;
        }
