JavaScript的随机码

代码如下：

<script language="JavaScript">
<!--
rnd.today=new Date();
rnd.seed=rnd.today.getTime();
function rnd()
{
rnd.seed = (rnd.seed*9301+49297) % 233280;
return rnd.seed/(233280.0);
};

function rand(number)
{
return Math.ceil(rnd()*number);
};
document.write(rand(100000));
 -->
</script>
