jQuery 时间戳转化成时间

//时间转换
function   formatDate(now)   {
var   now= new Date(now);
var   year=now.getFullYear();
var   month=now.getMonth()+1;
var   date=now.getDate();
var   hour=now.getHours();
var   minute=now.getMinutes();
var   second=now.getSeconds();
return   year+"年"+fixZero(month,2)+"月"+fixZero(date,2)+"日"+fixZero(hour,2)+":"+fixZero(minute,2)+":"+fixZero(second,2);
}
//时间如果为单位数补0
function fixZero(num,length){
var str=""+num;
var len=str.length;     var s="";
for(var i=length;i-->len;){
s+="0";
}
return s+str;
}
