代码如下:

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<title></title> 
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> 
<script type="text/javascript"> 
var t; 
var speed = 2;//图片切换速度 
var nowlan=0;//图片开始时间 
function changepic() { 
var imglen = $("div[name='pic']").find("div").length; 
$("div[name='pic']").find("div").hide(); 
$("div[name='pic']").find("div").eq(nowlan).show(); 
nowlan = nowlan+1 ==imglen ?0:nowlan + 1; 
t = setTimeout("changepic()", speed * 1000); 
} 
onload = function () { changepic(); } 
$(document).ready(function () { 
//鼠标在图片上悬停让切换暂停 
$("div[name='pic']").hover(function () { clearInterval(t); }); 
//鼠标离开图片切换继续 
$("div[name='pic']").mouseleave(function () { changepic(); }); 
}); 
</script> 
</head> 
<body> 
<div name="pic" style="float:left; position:relative;overflow:hidden;width:300px;height:240px;" > 
<div><img width="300" height="240" src="Chrysanthemum.jpg" alt="1"/></div> 
<div><img width="300" height="240" src="Desert.jpg" alt="2"/></div> 
<div><img width="300" height="240" src="Hydrangeas.jpg" alt="3"/></div> 
</div>
