一、楼层滚动效果图如下

1. 下图是纯Css实现的楼层滚动

在这里插入图片描述

2.通过Js优化后的楼层滚动如下图(🌹🌹)

在这里插入图片描述

二、楼层滚动（Css实现）

1.滚动原理

使用了一个 Css的属性值 scroll-behavior 。对应的信息可以查找网上的资料。
使用了锚点功能。和对应的 标签上的 id属性

2.代码如下

<!DOCTYPE html>
<html lang="en"><head><meta charset="UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>Document</title><style>* {padding: 0;margin: 0;}main {width: auto;height: 100vh;padding: 0 10px;overflow-y: scroll;scroll-behavior: smooth;}body ul {position: fixed;top: 50px;right: 50px;background-color: aliceblue;}ul li {width: 100%;height: 35px;line-height: 35px;text-align: center;border-bottom: 1px solid black;list-style: none;}ul li:active{background-color: rgb(255, 170, 0);}a {text-decoration: none;}a:hover {color: brown;}</style>
</head><body><ul><li> <a href="#sectionOne"> sectionOne</a> </li><li> <a href="#sectionTwo"> sectionTwo</a> </li><li> <a href="#sectionThree"> sectionThree</a> </li><li> <a href="#sectionFour"> sectionFour</a> </li><li> <a href="#sectionFive"> sectionFive</a> </li><li> <a href="#sectionSix"> sectionSix</a> </li><li> <a href="#sectionSeven"> sectionSeven</a> </li><li> <a href="#sectionEight"> sectionEight</a> </li></ul><main><section id="sectionOne" style="height: 500px;background-color: rgb(81, 185, 245);margin-bottom: 30px;">sectionOne</section><section id="sectionTwo" style="height: 500px;background-color: rgb(172, 176, 180);margin-bottom: 30px;">sectionTwo</section><section id="sectionThree" style="height: 500px;background-color: rgb(87, 216, 201);margin-bottom: 30px;">sectionThree</section><section id="sectionFour" style="height: 500px;background-color: aliceblue;margin-bottom: 30px;">sectionFour</section><section id="sectionFive" style="height: 500px;background-color: rgb(180, 153, 74);margin-bottom: 30px;">sectionFive</section><section id="sectionSix" style="height: 500px;background-color: rgb(96, 99, 175);margin-bottom: 30px;">sectionSix</section><section id="sectionSeven" style="height: 500px;background-color: rgb(224, 70, 238);margin-bottom: 30px;">sectionSeven</section><section id="sectionEight" style="height: 500px;background-color: rgb(226, 141, 101);margin-bottom: 30px;">sectionEight</section></main></body><script></script></html>

三、楼层滚动（Js+Css优化后的楼层滚动）

HTML、CSS代码如下

<style>* {padding: 0;margin: 0;}main {width: auto;height: 100vh;padding: 0 10px;overflow-y: scroll;scroll-behavior: smooth;}body ul {position: fixed;top: 50px;right: 50px;background-color: aliceblue;}ul li {width: 100%;height: 35px;line-height: 35px;text-align: center;border-bottom: 1px solid black;list-style: none;}a {display: inline-block;width: 100%;height: 100%;text-decoration: none;}a:hover {color: brown;}</style>

<body><ul><li><a href="#sectionOne"> sectionOne</a></li><li><a href="#sectionTwo"> sectionTwo</a></li><li><a href="#sectionThree"> sectionThree</a></li><li><a href="#sectionFour"> sectionFour</a></li><li><a href="#sectionFive"> sectionFive</a></li><li><a href="#sectionSix"> sectionSix</a></li><li><a href="#sectionSeven"> sectionSeven</a></li><li><a href="#sectionEight"> sectionEight</a></li></ul><main><section id="sectionOne" style="height: 500px;background-color: rgb(81, 185, 245);margin-bottom: 30px;">sectionOne</section><section id="sectionTwo" style="height: 500px;background-color: rgb(172, 176, 180);margin-bottom: 30px;">sectionTwo</section><section id="sectionThree" style="height: 500px;background-color: rgb(87, 216, 201);margin-bottom: 30px;">sectionThree</section><section id="sectionFour" style="height: 500px; background-color: aliceblue; margin-bottom: 30px">sectionFour</section><section id="sectionFive" style="height: 500px;background-color: rgb(180, 153, 74);margin-bottom: 30px;">sectionFive</section><section id="sectionSix" style="height: 500px;background-color: rgb(96, 99, 175);margin-bottom: 30px;">sectionSix</section><section id="sectionSeven" style="height: 500px;background-color: rgb(224, 70, 238);margin-bottom: 30px;">sectionSeven</section><section id="sectionEight" style="height: 500px;background-color: rgb(226, 141, 101);margin-bottom: 30px;">sectionEight</section></main>
</body>

JS代码如下

<script>let arr = [];let obj = nullvar sectionTags = document.querySelectorAll("section");var main = document.querySelector("main");var ul = document.querySelector("ul");var aTags = document.querySelectorAll("a");function removeColor() {aTags.forEach((element) => {element.style.background = "none";});}function getheight() {sectionTags.forEach((element) => {arr.push(element.offsetTop);});}function scrollMoveColor(e) {let scrollTop = e.srcElement.scrollTop;for (let i = 0; i < arr.length; i++) {if (scrollTop <= arr[i]) {removeColor();aTags[i].style.background = "rgb(255, 170, 0)";break;}}}getheight();main.addEventListener("scroll", scrollMoveColor);ul.addEventListener("click", function (e) {if (obj) {clearTimeout(obj)main.removeEventListener("scroll", scrollMoveColor);removeColor();e.target.style.background = "rgb(255, 170, 0)";}obj = setTimeout(() => {main.addEventListener("scroll", scrollMoveColor);}, 1000);});
</script>
