一个图片切换效果
在南京擎天科技的门户主页上面(http://www.skynj.com/webpages/about.jsp),有这么一个图片上实现自动滚入滚出,通过如下可以达到:

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

<title>图片自动滚入滚出</title>
</head>
<script language="JavaScript"> //js代码
var ar=new Array(); //用于存放图片路径（相对路径）
var nextNum=0;
ar[0]="image/01.jpg";
ar[1]="image/02.jpg";
ar[2]="image/03.jpg";
ar[3]="image/04.jpg";
function setTransition(){
if (document.all){
arrotator.filters.revealTrans.Transition=Math.floor(Math.random()*23);//设置图片切换
arrotator.filters.revealTrans.apply(); //应用图片切换
}
}
function playTransition(){
if (document.all)
arrotator.filters.revealTrans.play() //播放图片
}
function changePic(){
if(nextNum<ar.length-1)nextNum++;
else nextNum=0;
setTransition();
document.images.arrotator.src=ar[nextNum];
playTransition();
theTimer=setTimeout("changePic()", 3000); //3秒钟切换一张图片
}
</script>
<body>
<table border="0" cellspacing="0" cellpadding="0">
<tr align="center">
<td width="870" height="140" align="center">
<img style="filter: revealTrans(duration=3,transition=20)" width="805" height="280" name=arrotator>
<script language="JavaScript">changePic()</script>
</td>
</tr>
</table>
</body>
</html>
