代码如下：
<div align="center"> <SCRIPT LANGUAGE="JavaScript"> <!-- Begin var worldpop = 6080141683; // US Census estimate on 7/1/00 m = 7 d = 1 yr = 2000 var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"); var today=new Date(); var todayy=today.getYear(); if ((navigator.appName == "Microsoft Internet Explorer") && (todayy < 2000)) todayy="19" + todayy; if (navigator.appName == "Netscape") todayy = 1900 + todayy; function outputComma(number) { // (c) irt.org number = '' + number; if (number.length > 3) { var mod = number.length%3; var output = (mod > 0 ?
