利用JAVASCRIPT制作简单动画(转)

如果你需要改变动画播放速度,
比如每5秒换一张图片
改变setTimeout("imgturn(´" +numb+ "´)", 1000)中的1000为5000

<html>
<head>
<title></title>

<script language="JavaScript">
<!--
//请先准备几张JPG图片格式的,名字是demo1.jpg,demo2.jpg,demo3.jpg
if (document.images) {
demo1 = new Image();
demo1.src = "../../images/demo1.jpg";

demo2 = new Image();
demo2.src = "../../images/demo2.jpg";

demo3 = new Image();
demo3.src = "../../images/demo3.jpg";
}

function timeimgs(numb) {
thetimer = setTimeout("imgturn(´" +numb+ "´)", 1000);
}

function imgturn(numb) {
if (document.images) {

if (numb == "3") {
document["demo"].src = eval("demo3.src");
timeimgs(´1´);
}

else { document["demo"].src = eval("demo" + numb + ".src");

timeimgs(numb = ++numb);
}
}
}

// -->
</script>

</head>
<body onload="timeimgs(´2´);">

<img src="../../images/demo1.jpg" name="demo" width="100" height="100" alt="demo">[@more@]
