碰到一个用javascript实现随机跳转页面实例，发布出来，共同研究下，或许有用哦。
请看下面的实例
<html>
<head>
<title>Please waiting...</title>
<script language="javascript">
<!--
function urlList(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z)
{
this[0]=a;
this[1]=b;
this[2]=c;
this[3]=d;
this[4]=e;
this[5]=f;
this[6]=g;
this[7]=h;
this[8]=i;
this[9]=j;
this[10]=k;
this[11]=l;
this[12]=m;
this[13]=n;
this[14]=o;
this[15]=p;
this[16]=q;
this[17]=r;
this[18]=s;
this[19]=t;
this[20]=u;
this[21]=v;
this[22]=w;
this[23]=x;
this[24]=y;
this[25]=z;
}
function selectPage(list)
{
var today=new Date();
var page=today.getSeconds()%5;
window.open(list[page],"_self");
}
var choices=new urlList("");
-->
</script>
</head>
<body onLoad="selectPage(choices)">
Please waiting...
</body>
</html>
