具体代码如下：
<!DOCTYPE HTML>
<html>
<head><style type="text/css">#box,#lucky{font-family: "黑体";font-size: 109px;color: #138eee;font-weight: 900;}#lucky{color: darkred;font-size: 60px;}</style></head>
<body><img src="timg.jpg" height="290px"/><span id="box">开奖了！</span><div id="lucky"></div>
<script>var list=['01','02','03','04','05','06','07','08','09','10','11'];var ar=[];var box=document.getElementById("box");var lucky=document.getElementById("lucky");var count=8;//初始化变量setTimeout("show()",1000);//1秒后调用show函数function show(){var num=Math.floor(Math.random()*list.length);box.innerHTML=list[num];//显示随机号码var mytime=null;mytime=setTimeout("show()",100);//跳动切换count--;//计数if(count<0){clearTimeout(mytime);//关闭定时器ar.push(list[num]);//添加数组元素list.splice(num,1);//删除数组元素lucky.innerHTML="本期幸运号码："+ar.join(" ");//输出if(ar.length<5){count=8;setTimeout("show()",1000); }else{setTimeout("box.innerHTML=;",1000);//清空 }}}
</script>
</body>
</html>
