 更新時(shí)間:2021年09月23日 09:08:49   作者:一個(gè)學(xué)前端的小菜鳥  
這篇文章主要為大家詳細(xì)介紹了js實(shí)現(xiàn)樓層滾動(dòng)效果,文中示例代碼介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了jquery實(shí)現(xiàn)滑動(dòng)樓梯效果,實(shí)現(xiàn)樓層的滾動(dòng)以及點(diǎn)擊樓層按鈕跳轉(zhuǎn)到對(duì)應(yīng)的樓層,代碼如下

html代碼:

<div style="height: 500px; background-color: black; color: #fff;">無(wú)意義的文本</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>

css代碼:

* {
         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;
        }

js代碼:

<script>
        var layers = document.querySelectorAll(".layer")
        var lis = document.querySelectorAll('li')
        for (let i = 0; i < lis.length; i++) {

            li.onclick = function (e) {

                var scrollTop = document.documentElement.scrollTop
                var offsetTop = layers[i].offsetTop

                            scrollTop -= 40
                            if (scrollTop - offsetTop < 40) {
                                // 如果最后一洞的距離小于40時(shí),直接設(shè)置偏移量為0
                                window.scrollTo(0, offsetTop)

                    }, 50)
                } else {
                    // 滾動(dòng)條向下移動(dòng)
                    // scrollTop <= offsetTop
                    var timer = setInterval(function () {
                        if (scrollTop < offsetTop) {
                            scrollTop += 40
                            if (offsetTop - scrollTop < 40) {
                                window.scrollTo(0, offsetTop)
                            } else {
                                window.scrollTo(0, scrollTop)
                            }
                        } else {
                            clearInterval(timer)
                        }
                    }, 50);
 
 
                }
 
            }
        }
  
        window.onscroll = function (e) {
            var scrollTop = document.documentElement.scrollTop || document.body.scrollTop
            layers.forEach(function (v, i) {
                if (v.clientHeight + v.offsetTop > scrollTop && scrollTop > v.offsetTop) {
                    // 滾動(dòng)的樓層到達(dá)頂部范圍,離開消失
                    lis[i].classList.add("active")
                } else {
                    lis[i].classList.remove("active")
                }
