JAVASCRIPT制作简单动画

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">
