原理就是获取到图片的src地址然后赋值给背景的URL地址
<!DOCTYPE html>
<html>
<head>
<meta charset="{CHARSET}">
<title></title>
<style type="text/css">
*{
margin: 0;
padding: 0;
}
body{
background: url(img/11.jpg) no-repeat ;
/*background-size: 100% ;*/
}
ul{
width: 200px;
/*background: red;*/
border: 1px solid pink;
overflow: hidden;
list-style: none;
margin:300px auto;
}
ul li{
float: left;
/*background: red;*/
width: 50%;
margin-top: 5px;
/*cursor:wait;*/
}
ul li img{
width: 100px;
}
</style>
</head>
<body>
<ul>
<li><img src="img/2.jpeg"/></li>
<li><img src="img/3.jpg"/></li>
<!--<li><img src="img/2.jpeg"/></li>
<li><img src="img/3.jpg"/></li>-->
</ul>
<script type="text/javascript">
var img = document.querySelector("ul").querySelectorAll("img")
for (var i=0; i<img.length; i++) {
img[i].onclick = function() {
// console.log(this.src)
document.body.style.backgroundImage = "url("+this.src+")";
}
}
</script>
</body>
</html>
