如何用js完成滚动视差的效果?
How to use js to complete the effect of scrolling parallax?
我是编程初学者,现在想完成一个效果!
当鼠标向下滚动时,屏幕上的元素会跟着位置偏移,当鼠标再次向上滚动时,元素也会偏移到原来的位置。
但是,当鼠标停止时,不能连续移动位置来实现滚动视差效果。
但是目前我想实现的效果是给一个固定的偏移位置
duck.style.transform = 'translateY(100px)';
这将导致元素在鼠标不滚动时移动。我该如何解决这个问题? ?
期望的效果类似于下面的 URL 示例

let duck = document.querySelector(".duck");
let cloud1 = document.querySelector(".cloud1");
let cloud2 = document.querySelector(".cloud2");
let cloud3 = document.querySelector(".cloud3");
$(document).on("scroll", function() {
if (window.pageYOffset > 0) {
duck.style.transform = "translateY(100px)";
cloud1.style.transform = "translateY(120px)";
cloud2.style.transform = "translateY(80px)";
cloud3.style.transform = "translateY(60px)";
// duck.style.transition = '2s';
} else {
duck.style.transform = "translateY(-100px)";
cloud1.style.transform = "translateY(-120px)";
cloud2.style.transform = "translateY(-80px)";
cloud3.style.transform = "translateY(-60px)";
}
});
.wrap {
position: relative;
background-color: #222;
height: 1000px;
}
.wrap .duck {
width: 300px;
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
transition: 1s;
}
.wrap .cloud1 {
position: absolute;
top: 60px;
width: 360px;
left: 30px;
transition: 2s;
}
.wrap .cloud2 {
position: absolute;
top: 200px;

width: 160px;
transition: 2s;
}
.wrap .cloud3 {
position: absolute;
top: 320px;
width: 560px;
transition: 2s;
}
