请问该如何用window.onload=function()写上一个定时器？
我已经做好了HTML页面如下:
<!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>无标题文档</title>
<style type="text/css">
#tab { overflow:hidden; width:400px; height:250px; position:relative; float:left;}
</style>
</head>
<body>
<div id="tab">
<img src="img/01.jpg" width="400" height="250"/>
<img src="img/02.jpg" width="400" height="250"/>
<img src="img/03.jpg" width="400" height="250"/>
</div>
<script>
</script>
</body>
</html>
如何用window.onload=function(){写上一个定时器},具体用JS怎么写...谢谢
