js实现轮播图的两种方式(构造函数、面向对象)

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

 
  
  
  
   *{ 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;}

  
 
 
  
   
    
    
    
    
   
   
    

     

     

     

     

    
   
   
    <
    >
   
  
  
 

2、面向对象

 
  
  
  
   *{ 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;}

  
 
 
  
   
    
    
    
    
   
   
    

     

     

     

     

    
   
   
    <
    >
