再来一个,这下可以称最简版了吧?

<SCRIPT LANGUAGE="JavaScript">
<!--
function toCHS(s){return s.constructor!=Number?s.constructor!=String?s.constructor!=Date?null:toCHS(s.getFullYear()+"")+"年"+toCHS(s.getMonth()+1)+"月"+toCHS(s.getDate())+"日"+toCHS(s.getHours())+"时"+toCHS(s.getMinutes())+"分"+toCHS(s.getSeconds())+"秒":s.replace(/\d/g,function(a){return"零一二三四五六七八九".charAt(parseInt(a))}): toCHS(((s>19?Math.floor(s/10):"")+(s>9?("十"):"")+(s%10==0&&s>0?"":s%10)))}
alert(toCHS(new Date()));
