原理

通过点击事件，获取点击的的图片的信息，在HTML背景图片的路径改变

css样式


<style>
 body{
 margin:0;
 padding:0;
 background:url(img/1.jpg) no-repeat;
 background-size:100% 100%;
 }
 #box{
 width:100%;
 height:130px;
 background:#999999;
 }
 #box ul{
 margin:0;
 padding:0;
 list-style:none;
 }
 #box ul li li,#box ul li img{
 width:180px;
 height:120px;
 float:left;
 margin:5px 60px;
 }
</style>

HTML源码


<body id="Body">
 <div id="box">
 <ul>
 <li><img src="img/1.jpg" /></li>
 <li><img src="img/2.jpg" /></li>
 <li><img src="img/3.jpg" /></li>
 <li><img src="img/4.jpg" /></li>
 <li><img src="img/5.jpg" /></li>
 </ul>
 </div>
</body>

JavaScript源码


<script>
 var oBody=document.getElementById('Body');
 var oImg=document.getElementsByTagName('img');
 for(var i=0;i<oImg.length;i++)
 {
 var oImgA=oImg[i];
 oImgA.index=i+1;
 oImgA.onclick=function(){
 //console.log(this);
 oBody.style.background='url(img/'+this.index+'.jpg) no-repeat';
 oBody.style.backgroundSize='100% 100%'; 
 };
 }
</script>
