图片轮播：

需要注意的HTML需要img标签，他和input标签一样，是非封闭的标签

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>广告轮播</title>

<script src="广告轮播.js"></script>

</head>

<body>

<img id="img1" src="data:image/rose.jpg" />

</body>

</html>

JavaScript：

现在只需要改变JavaScript中数组元素的值即可改变图片

// JavaScript Document

var imageArray = ['apple.jpg','rose.jpg'];

var timer;

var index = 1;

function rotateFunc(){

    var img = document.getElementById("img1");

    img.src = "image/"+imageArray[index];

    if(index==imageArray.length-1)

        index = 0;

    else

        index++;

    }

function startRotate(){

    timer = window.setInterval(rotateFunc,1000);

    }

window.addEventListener('load',startRotate,false);
