手动轮播图,为轮播图中的一种,轮播图主要有无缝轮播,手动轮播,延迟轮播,切换轮播等等。。。

轮播图主要用于展现图片,新出商品,词条,又能美观网页。?网页中增加动态效果。

手动轮播,是小编认为最简单的一种轮播方式,既能左右翻页,还能通过悬浮按钮,快速预览图片,所以今天就给大家写一个原生js手动轮播图。

一,利用 制作手动轮播图,首先排版。

引入默认样式表(可以手写);

<  rel=\"stylesheet\" href=\"css/Default style sheet.css\" rel=\"external nofollow\" rel=\"external nofollow\" />//本博客有css默认样式表可以下载。

div排版布局:

<body>
 <div id=\"box\">
 <div id=\"lunbo\"><img src=\"img/1.jpg\" id=\"img\"/></div>
 <div id=\"left\"><</div>
 <div id=\"right\">></div>
 <div id=\"radiu\">
 <ul>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li>
 </ul>
 </div>
 </div>
 </body>

二,定义div的CSS样式,给div设置宽高,定位。

<style>
 body{
 background: darkturquoise;
 }
 #box{
 height:320px;
 width:480px;
 margin: 3px auto;
 border: 2px solid red;
 }
 #lunbo{
 height: 292px;
 width:453px;
 border: 1px solid yellow;
 margin: 0px auto;
 position: relative;
 }
 #left{
 height: 60px;
 width: 60px;
 font-size: 60px;
 text-align: center;
 line-height: 60px;
 position: absolute;
 top:150px;
 left: 440px;
 color: black;
 }
 #right{
 height: 60px;
 width: 60px;
 font-size: 60px;
 text-align: center;
 line-height: 60px;
 position: absolute;
 top:150px;
 left: 880px;
 color: black;
 }
 #radiu{
 height: 30px;
 width: 240px;
 text-align: center;
 
 margin: 0px auto;
 }
 #radiu li{
 float: left;
 background: white;
 height: 30px;
 width: 30px;
 line-height: 30px;
 border-radius:50% ;
 margin-right:6px;
 }
 .active{
 background: orange;
 color: ;
 }
 </style>
原生js代码:
< >
 window. =function(){
 var ridiu=document.getElementById(\"radiu\")
 var right=document.getElementById(\"right\");
 var left=document.getElementById(\"left\")
 var img=document.getElementById(\"img\");
 var oli=ridiu.getElementsByTagName(\"li\")
 var arry=[\'img/1.jpg\',\'img/2.jpg\',\'img/3.jpg\',\'img/4.jpg\',\'img/5.jpg\']
  var a=null;
 
  right. =function(){
   a++
   if(a>arry.length-1){
   a=0;
   }
  
   img.src=arry[a]
  }
  left. =function(){
   a--
   if(a<0){
   a=arry.length-1;
   }
  
   img.src=arry[a]
  
  }
  
  for (var i=0;i<oli.length;i++) {
   
   oli[i]. =function(){
   a++
   if(a==arry.length){
   a=0;
   }
    img.src=arry[a];
   }
   
  }
 
 }
 </ >
