先上图
鼠标滑过那张图，显示完整的哪张图，移除则复位：
简单的CSS加JS操作DOM实现：
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>sliding doors</title>
<link rel="stylesheet" href="styles/reset.css" />
<link rel="stylesheet" href="styles/slidingdoors.css" />
<script src="scripts/slidingdoors.js"></script>
</head>
<body>
<div id='container'>
<img src="images/door1.png" alt="1080P神器" title="1080P神器" />
<img src="images/door2.png" alt="5.5寸四核" title="5.5寸四核" />
<img src="images/door3.png" alt="四核5寸" title="四核5寸" />
<img src="images/door4.png" alt="5.7寸机皇" title="5.7寸机皇" />
</div>
</body>
</html>css:
#container {
height: 477px;
margin: 0 auto;
border-right: 1px solid #ccc;
border-bottom: 1px solid #ccc;
overflow: hidden;
position: relative;
}
#container img {
position: absolute;
display: block;
left: 0;
border-left: 1px solid #ccc;
}js操作：
window.onload = function() {
//容器对象
var box = document.getElementById('container');
//获得图片NodeList对象集合
var imgs = box.getElementsByTagName('img');
//单张图片的宽度
var imgWidth = imgs[0].offsetWidth;
//设置掩藏门体露出的宽度
var exposeWidth = 180;
//设置容器总宽度
var boxWidth = imgWidth + (imgs.length - 1) * exposeWidth;
box.style.width = boxWidth + 'px';
//设置每道门的初始位置
function setImgsPos() {
for (var i = 1, len = imgs.length; i < len; i++) {
imgs[i].style.left = imgWidth + exposeWidth * (i - 1) + 'px';
}
}
setImgsPos();
//计算每道门打开时应移动的距离
var translate = imgWidth - exposeWidth;
//为每道门绑定事件
for (var i = 0, len = imgs.length; i < len; i++) {
//使用立即调用的函数表答式，为了获得不同的i值
(function(i) {
imgs[i].onmouseover = function() {
//先将每道门复位
setImgsPos();
//打开门
for (var j = 1; j <= i; j++) {
imgs[j].style.left = parseInt(imgs[j].style.left, 10) - translate + 'px';
//imgs[j].style.left = j*exposeWidth +"px";
}
};
imgs[i].onmouseout = function(){
setImgPos();
};
})(i);
}
