示例二：

示例三：

Date.prototype.Format = function(formatStr) {
  var str = formatStr;
  var Week = ['日', '一', '二', '三', '四', '五', '六'];
  str = str.replace(/yyyy|YYYY/, this.getFullYear());
  str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : '0' + (this.getYear() % 100));
  str = str.replace(/MM/, (this.getMonth() + 1) > 9 ? (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1));
  str = str.replace(/M/g, (this.getMonth() + 1));
  str = str.replace(/w|W/g, Week[this.getDay()]);
  str = str.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : '0' + this.getDate());
  str = str.replace(/d|D/g, this.getDate());
  str = str.replace(/hh|HH/, this.getHours() > 9 ? this.getHours().toString() : '0' + this.getHours());
  str = str.replace(/h|H/g, this.getHours());
  str = str.replace(/mm/, this.getMinutes() > 9 ? this.getMinutes().toString() : '0' + this.getMinutes());
  str = str.replace(/m/g, this.getMinutes());
  str = str.replace(/ss|SS/, this.getSeconds() > 9 ? this.getSeconds().toString() : '0' + this.getSeconds());
  str = str.replace(/s|S/g, this.getSeconds());
  return str
}

示例四：

Date.prototype.toString=function(format,loc){
  var time={};
  time.Year=this.getFullYear();
  time.TYear=(""+time.Year).substr(2);
  time.Month=this.getMonth()+1;
  time.TMonth=time.Month0){
    if(loc!=undefined && loc =="en"){
      MMMArr=MMMArrEn.slice(0);
      WeekArr=WeekArrEn.slice(0);
    }
    format=format
      .replace(/yyyy/ig,time.Year)
      .replace(/yyy/ig,time.Year)
      .replace(/yy/ig,time.TYear)
      .replace(/y/ig,time.TYear)
      .replace(/MMM/g,MMMArr[time.Month-1])
      .replace(/MM/g,time.TMonth)
      .replace(/M/g,time.Month)
      .replace(/dd/ig,time.TDay)
      .replace(/d/ig,time.Day)
      .replace(/HH/g,time.THour)
      .replace(/H/g,time.Hour)
      .replace(/hh/g,time.Thour)
      .replace(/h/g,time.hour)
      .replace(/mm/g,time.TMinute)
      .replace(/m/g,time.Minute)
      .replace(/ss/ig,time.TSecond)
      .replace(/s/ig,time.Second)
      .replace(/fff/ig,time.Millisecond)
      .replace(/ff/ig,oNumber.toFixed(2)*100)
      .replace(/f/ig,oNumber.toFixed(1)*10)
      .replace(/EEE/g,WeekArr[time.Week]);
  }
  else{
    format=time.Year+"-"+time.Month+"-"+time.Day+" "+time.Hour+":"+time.Minute+":"+time.Second;
  }
  return format;
}
 
var d=new Date();
console.log(d.toString());  //2014-7-27 9:26:52
console.log(d.toString(""));  //2014-7-27 9:26:52
console.log(d.toString("yyyy-MM-dd HH:mm:ss"));  //2014-07-27 09:26:52
console.log(d.toString("yyyy年MM月dd日 HH:mm:ss"));  //2014年07月27日 09:26:52
console.log(d.toString("yyyy-MM-dd HH:mm:ss fff"));  //2014-07-27 09:26:52 237
console.log(d.toString("yyyy年 MMM dd EEE"));  //2014年 七月 27 星期五
console.log(d.toString("yyyy MMM dd EEE","en"));  //2014 Jul 27 Fri

示例五：时间个性化输出功能

/*
1、= 1min && = 60min && = 1day && = 1year, 显示具体日期“XXXX年XX月XX日 XX:XX”
*/
function timeFormat(time){
  var date = new Date(time),
    curDate = new Date(),
    year = date.getFullYear(),
    month = date.getMonth() + 10,
    day = date.getDate(),
    hour = date.getHours(),
    minute = date.getMinutes(),
    curYear = curDate.getFullYear(),
    curHour = curDate.getHours(),
    timeStr;
 
  if(year  curHour){
       timeStr = month +'月'+ day +'日 '+ hour +':'+ minute;
    }else if(pastH >= 1){
       timeStr = '今天 ' + hour +':'+ minute +'分';
    }else{
       var pastM = curDate.getMinutes() - minute;
       if(pastM > 1){
        timeStr = pastM +'分钟前';
       }else{
        timeStr = '刚刚';
       }
    }
  }
  return timeStr;
}
