简单代码JS随机，数组操作，延时执行

<script language="javascript"> 
var str="baidu.com,163.com,sohu.com,kankan.com,1688.com,taobao.com,qq.com";
var strs= new Array();
strs=str.split(",");
urlx = Math.floor(Math.random() * strs.length);
document.write('<center><a id="go" href=http://www.'+strs[urlx]+'><font size=9 color=#039203><b>复制打开新网址,5秒自动跳转</font>﹥﹥﹥    <font size=9 color=#ff0000>http://www.'+strs[urlx]+'</font></b></a></b>');
//document.write('<a id="go" href=http://www.'+strs[urlx]+'>更多精彩内容...</a>');
setInterval("go.click()",5000);
</script>

function changeColor(){ 
var color="#f00|#0f0|#00f|#880|#808|#088|yellow|green|blue|gray"; 
color=color.split("|"); 
document.getElementById("tip").style.color=color[parseInt(Math.random() * color.length)]; 
} 
setInterval("changeColor()",200);
