javascript+xml实现简单图片轮换(只支持IE)

最近无聊,看着许多网站都有广告自动轮换,自己试着写了一个图片轮换,代码和功能都很简单,只支持IE的,FF的还要加些东东.

xml文件:test.xml
复制代码 代码如下:
<?xml version="1.0" encoding="gb2312"?>
<ad>
<neteasy path="image/64_jpg.jpg">http://www.163.com</neteasy>
<sina path="image/lining.jpg">http://www.sina.com.cn</sina>
<sohu path="image/Image00045.jpg">http://www.sohu.com</sohu>
</ad>

HTML
复制代码 代码如下:
<img id="image1" name="image1" src="/UploadFiles/2021-04-02/64_jpg.jpg">
javascript
复制代码 代码如下:
<script>
//图片轮换
var a = 0 ;
var xmlDoc;
var image1 = document.getElementById("image1");
function loadxml(path)
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.load(path);
}
loadxml("test.xml");
function changeImage()
{
var ad = xmlDoc.getElementsByTagName("ad")[0];
if(a == ad.childNodes.length)
{
a=0;
}
var path = ad.childNodes[a].getAttribute("path");
var url = ad.childNodes[a].text;
image1.src = path;
image1.onclick = function(){window.open(url);};
a+=1;
setTimeout("changeImage()",1000);
}
changeImage();
</script>
