这篇文章主要为大家详细介绍了原生js轮播特效js原生代码，简单实用的代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

  作为一名前端工程师js原生代码，手写轮播图应该是最基本掌握的技能，以下是我自己原生js写的轮播，欢迎指点批评：

  首先css代码

  <pre class="brush:css;">a{text-decoration:none;color:#3DBBF5;}
*{

margin: 0;
padding: 0;

}
.wrapper{

width: 400px;
height: 300px;
margin: 100px auto;

}
#lunbo{

position: relative;
overflow: hidden;

}
#list{

position: relative;
white-space: nowrap; // 这块用行元素模拟，所以才用该属性，块元素可修改这块

}
#list span{

display: inline-block;
width: 400px;
height: 300px;
text-align: center;
line-height: 300px;
font-weight: bold;
font-size: 100px;
color: #fff;

}
#buttons{

position: absolute;
bottom: 0;
text-align: center;
width: 100%;
height: 40px;
line-height: 40px;

}
#buttons span{

display: inline-block;
width: 15px;
height: 5px;
background: #fff;
margin: 0 10px;
cursor: pointer;
transition: all .5s;

}
#buttons span.on{

height: 20px;

}
.arrow{

position: absolute;
top: 50%;
transform: translateY(-50%);
font-size: 80px;
font-weight: bold;
color: #fff;
opacity: .3;
transition: all .5s;

}
.wrapper:hover .arrow{

opacity: 1;

}
#prev{

left: 10px;

}
#next{

right: 10px;
</pre>

  登录后复制

  然后HTML代码

  <pre class="brush:php;toolbar:false"><p class="wrapper">
<p id="lunbo">

<p id="list" style="left: -400px;">
 5123451


&emsp;&emsp;
 
 
 
 
 


[</a
a href="javascript:;" id="next" class="arrow">][5]

</p>
</p></pre></p>

  登录后复制

  最后js代码

<p><pre class="brush:js;">window.onload=function () {
var lunBo = document.getElementById("lunbo");
var list = document.getElementById("list");
var btn = document.getElementById("buttons").getElementsByTagName('span');
var prev = document.getElementById("prev");
var next = document.getElementById('next');
var interval = 3000;
var timer;
var index = 1;
var animated = false;
for (var i=0;i
