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

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 < curYear){
    timeStr = year +'年'+ month +'月'+ day +'日 '+ hour +':'+ minute;
  }else{
    var pastTime = curDate - date,
      pastH = pastTime/3600000;
 
    if(pastH > 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;
