/*楼主的图片我看不清楚，我用百度中心的图替代一下。CSS改成自己需要的，我中间加了个遮蔽层，楼主觉得不好看可以删掉*/
这段JS图片轮显代码应该怎么改？
试试这个图片切换
有12345数字一起切换
鼠标点一下数字会变换到另一张图片，不点就会自动换
用js实现图片轮显
一、思路:页面加载、获取整个容器、所有放数字索引的li及放图片列表的ul、定义放定时器的变量、存放当前索引的变。
二、提示:
1、 index不能一直无限制的递增下去，需做判断
2、调用切换图片函数时需将递增之后的index作为参数传过去
body
div class="wrap" id='wrap'
ul id="pic"
liimg src="1.jpg" alt=""/li
liimg src="2.jpg" alt=""/li
liimg src="3.jpg" alt=""/li
liimg src="4.jpg" alt=""/li
liimg src="5.jpg" alt=""/li
/ul
ol id="list"
li class="on"1/li
li2/li
li3/li
li4/li
li5/li
/ol
input value="上一张" onclick="" type="button"/
input value="下一张" onclick="" type="button"/
/div
script type="text/javascript"
var wrap=document.getElementById('wrap'),
pic=document.getElementById('pic').getElementsByTagName("li"),
list=document.getElementById('list').getElementsByTagName('li'),
index=0;
function autoPlay (type) {//type==0--上一张;type==1--下一张
if(type==0)index--;
else if(type==1)index++;
if (index = pic.length) index = 0;//如果Index大于照片数量就从第一张开始
changePic(index);
}
// 定义图片切换函数
function changePic (curIndex) {
for (var i = 0; i pic.length; ++i) {
pic[i].style.display = "none";
list[i].className = "";
}
pic[curIndex].style.display = "block";
list[curIndex].className = "on";
}
/script
/body
我只是大致写的一个例子，你自己调试。
