本文实例为大家分享了js实现轮播图的具体代码，供大家参考，具体内容如下
1、构造函数
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style type='text/css'>
*{ margin:0; padding:0;}
#wrap{
width:500px;
height:360px;
margin:100px auto;
position:relative;
}
#pic{
width:500px;
height:360px;
position:relative;
}
#pic img{
width: 100%;
height: 100%;
position:absolute;
top:0;
left:0;
display:none;
}
#tab{
width:105px;
height:10px;
position:absolute;
bottom:10px;
left:50%;
margin-left:-50px;
}
#tab ul li{
width:10px;
height:10px;
margin:0 5px;
background:#bbb;
border-radius:100%;
cursor:pointer;
list-style:none;
float:left;
}
#tab ul li.on{ background:#f60;}
#btn div{
width:40px;
height:40px;
position:absolute;
top:50%;
margin-top:-20px;
color:#fff;
background:#999;
background:rgba(0,0,0,.5);
font-size:20px;
font-weight:bold;
font-family:'Microsoft yahei';
line-height:40px;
text-align:center;
cursor:pointer;
}
#btn div#left{ left:0;}
#btn div#right{ right:0;}
</style>
</head>
<body>
<div id="wrap">
<div id="pic">
<img src="/UploadFiles/2021-04-02/1.jpg">
2、面向对象
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style type='text/css'>
*{ margin:0; padding:0;}
#wrap{
width:500px;
height:360px;
margin:100px auto;
position:relative;
}
#pic{
width:500px;
height:360px;
position:relative;
}
#pic img{
width: 100%;
height: 100%;
position:absolute;
top:0;
left:0;
display:none;
}
#tab{
width:105px;
height:10px;
position:absolute;
bottom:10px;
left:50%;
margin-left:-50px;
}
#tab ul li{
width:10px;
height:10px;
margin:0 5px;
background:#bbb;
border-radius:100%;
cursor:pointer;
list-style:none;
float:left;
}
#tab ul li.on{ background:#f60;}
#btn div{
width:40px;
height:40px;
position:absolute;
top:50%;
margin-top:-20px;
color:#fff;
background:#999;
background:rgba(0,0,0,.5);
font-size:20px;
font-weight:bold;
font-family:'Microsoft yahei';
line-height:40px;
text-align:center;
cursor:pointer;
}
#btn div#left{ left:0;}
#btn div#right{ right:0;}
</style>
</head>
<body>
<div id="wrap">
<div id="pic">
<img src="/UploadFiles/2021-04-02/1.jpg">
