js實現樓層滾動效果
阿新 • • 發佈：2021-09-23
本文例項為大家分享了實現滑動樓梯效果，實現樓層的滾動以及點選樓層按鈕跳轉到對應的樓層，程式碼如下
html程式碼：
<div style="height: 500px; background-color: black; color: #fff;">無意義的文字</div>
<div class="layerbox">
<div class="layer num1">第一層</div>
<div class="layer num2">第二層</div>
<div class="layer num3">第三層</div>
<div class="layer num4">第四層</div>
</div>
<div class="nav">
<ul>
<li>1F</li>
<li>2F</li>
<li>3F</li>
<li>4F</li>
</ul>
</div>
程式碼：
* {
margin: 0;
padding: 0;
}
.layer {
height: 300px;
font-size: 80px;
color: white;
text-align: center;
}
.num1 {
background-color: red;
}
.num2 {
background-color: blue;
}
.num3 {
background-color: yellow;
}
.num4 {
background-color: green;
}
.nav {
position: fixed;
right: 50px;
bottom: 400px;
background-color: pink;
}
ul {
list-style: none;
}
ul li {
padding: 10px;
width: 50px;
height: 50px;
line-height: 50px;
text-align: center;
border: 1px solid #000;
}
ul li.active {
background-color: crimson;
}程式碼：
<script>
var layers = document.querySelectorAll(".layer")
var lis = document.querySelectorAll('li')
for (let i = 0; i < lis.length; i++) {
const li = lis[i]
li.onclick = function (e) {
//頁面的偏移量，原來的頁面滾動的距離
var scrollTop = document.documentElement.scrollTop
var offsetTop = layers[i].offsetTop
if (scrollTop > offsetTop) {
// 滾動條向上移動
var timer = setInterval(function () {
if (scrollTop > zRBuUh
