var m = now.getMonth()+1;
var d = now.getDate();
var x = now.getDay();
var hour = now.getHours();
var day =new Array("日","一","二","三","四","五","六");
var xingqi = day[x];
var mi =now.getMinutes();
var s = now.getSeconds();
var t =document.getElementById("t");
t.innerHTML="今天是"+y+"年"+m+"月"+d+"日"+"星期"+xingqi+","+hour+":"+mi+":"+s;
