先看一眼效果图：
代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style>
*{padding:0;margin:0;}
#content{width:550px;height:300px;margin:50px auto;position:relative;}
#content input{width:60px;height:30px;margin-right:10px;}
#content div{diplay:inline-block;position:absolute;bottom:0;;border:1px solid #ccc;width:250px;height:250px;background:url(img/loader_ico.gif) no-repeat center #f1f1f1;}
#content div.left{left:0;}
#content div.right{right:0;}
#content div span{display:inline-block;width:250px;height:30px;line-height:30px;background:#ccc;color:red;text-align:center;}
#content div img {height:250px;width:250px;}
</style>
<script>
window.onload = function () {
var content = $('content'),prev = $('prev'),next = $('next'),
left = $('left'),right = $('right');
var aSpan = content.getElementsByTagName('span');
var aImg = content.getElementsByTagName('img');
var arr = [
['img/1.png','img/2.png','img/3.png','img/4.png'],
['img/2.png','img/3.png','img/4.png']
];
var num = [0, 0];
// 初始化
for ( var i = 0; i < aSpan.length; i++ ) {
carousel(i);
aImg[i].index = i;
aImg[i].onclick = function () {
if (num[this.index] === arr[this.index].length - 1) num[this.index] = -1;
num[this.index]++;
carousel(this.index);
}
}
// 下一组
next.onclick = function () {
for ( var i = 0; i < aSpan.length; i++ ) {
if (num[i] === arr[i].length - 1) num[i] = -1;
num[i]++;
carousel(i);
}
}
// 上一组
prev.onclick = function () {
for ( var i = 0; i < aSpan.length; i++ ) {
if (num[i] === 0) num[i] = arr[i].length;
num[i]--;
carousel(i);
}
}
function carousel(index) {
aSpan[index].innerHTML = num[index] + 1 + ' / ' + arr[index].length;
aImg[index].src = arr[index][num[index]];
}
function $(id) {return document.getElementById(id);}
}
</script>
