方法一：

// 对Date的扩展，将 Date 转化为指定格式的String
// 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符， 
// 年(y)可以用 1-4 个占位符，毫秒(S)只能用 1 个占位符(是 1-3 位的数字) 
// 例子： 
// (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 
// (new Date()).Format("yyyy-M-d h:m:s.S")   ==> 2006-7-2 8:9:4.18 
Date.prototype.Format = function (fmt) { //author: meizz 
  var o = {
    "M+": this.getMonth() + 1, //月份 
    "d+": this.getDate(), //日 
    "h+": this.getHours(), //小时 
    "m+": this.getMinutes(), //分 
    "s+": this.getSeconds(), //秒 
    "q+": Math.floor((this.getMonth() + 3) / 3), //季度 
    "S": this.getMilliseconds() //毫秒 
  };
  if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
  for (var k in o)
  if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
  return fmt;

调用方式：

var time1 = new Date().Format("yyyy-MM-dd");
var time2 = new Date().Format("yyyy-MM-dd HH:mm:ss");

方法二：

<script language="javascript" type="text/javascript"> 
<!-- /** * 对Date的扩展，将 Date 转化为指定格式的String * 月(M)、日(d)、12小时(h)、24小时(H)、分(m)、秒(s)、周(E)、季度(q)
  可以用 1-2 个占位符 * 年(y)可以用 1-4 个占位符，毫秒(S)只能用 1 个占位符(是 1-3 位的数字) * eg: * (new
  Date()).pattern("yyyy-MM-dd hh:mm:ss.S")==> 2006-07-02 08:09:04.423   
 * (new Date()).pattern("yyyy-MM-dd E HH:mm:ss") ==> 2009-03-10 二 20:09:04   
 * (new Date()).pattern("yyyy-MM-dd EE hh:mm:ss") ==> 2009-03-10 周二 08:09:04   
 * (new Date()).pattern("yyyy-MM-dd EEE hh:mm:ss") ==> 2009-03-10 星期二 08:09:04   
 * (new Date()).pattern("yyyy-M-d h:m:s.S") ==> 2006-7-2 8:9:4.18   
 */    
Date.prototype.pattern=function(fmt) {     
  var o = {     
  "M+" : this.getMonth()+1, //月份     
  "d+" : this.getDate(), //日     
  "h+" : this.getHours()%12 == 0 &#63; 12 : this.getHours()%12, //小时     
  "H+" : this.getHours(), //小时     
  "m+" : this.getMinutes(), //分     
  "s+" : this.getSeconds(), //秒     
  "q+" : Math.floor((this.getMonth()+3)/3), //季度     
  "S" : this.getMilliseconds() //毫秒     
  };     
  var week = {     
  "0" : "/u65e5",     
  "1" : "/u4e00",     
  "2" : "/u4e8c",     
  "3" : "/u4e09",     
  "4" : "/u56db",     
  "5" : "/u4e94",     
  "6" : "/u516d"    
  };     
  if(/(y+)/.test(fmt)){     
    fmt=fmt.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length));     
  }     
  if(/(E+)/.test(fmt)){     
    fmt=fmt.replace(RegExp.$1, ((RegExp.$1.length>1) &#63; (RegExp.$1.length>2 &#63; "/u661f/u671f" : "/u5468") : "")+week[this.getDay()+""]);     
  }     
  for(var k in o){     
    if(new RegExp("("+ k +")").test(fmt)){     
      fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) &#63; (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length)));     
    }     
  }     
  return fmt;     
}    
   
var date = new Date();   
window.alert(date.pattern("yyyy-MM-dd hh:mm:ss"));

方法三：

Date.prototype.format = function (mask) { 
  var d = this;
  var zeroize = function (value, length) {
      if (!length) length = 2;
      value = String(value);
      for (var i = 0, zeros = ''; i < (length - value.length); i++) {
        zeros += '0';
      }
      return zeros + value;
    };
  return mask.replace(/"[^"]*"|'[^']*'|/b ( &#63; : d {
    1, 4
  } | m {
    1, 4
  } | yy( &#63; : yy) &#63; | ([hHMstT]) / 1 &#63; | [lLZ]) / b / g, function ($0) {
    switch ($0) {
    case 'd':
      return d.getDate();
    case 'dd':
      return zeroize(d.getDate());
    case 'ddd':
      return ['Sun', 'Mon', 'Tue', 'Wed', 'Thr', 'Fri', 'Sat'][d.getDay()];
    case 'dddd':
      return ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'][d.getDay()];
    case 'M':
      return d.getMonth() + 1;
    case 'MM':
      return zeroize(d.getMonth() + 1);
    case 'MMM':
      return ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'][d.getMonth()];
    case 'MMMM':
      return ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'][d.getMonth()];
    case 'yy':
      return String(d.getFullYear()).substr(2);
    case 'yyyy':
      return d.getFullYear();
    case 'h':
      return d.getHours() % 12 || 12;
    case 'hh':
      return zeroize(d.getHours() % 12 || 12);
    case 'H':
      return d.getHours();
    case 'HH':
      return zeroize(d.getHours());
    case 'm':
      return d.getMinutes();
    case 'mm':
      return zeroize(d.getMinutes());
    case 's':
      return d.getSeconds();
    case 'ss':
      return zeroize(d.getSeconds());
    case 'l':
      return zeroize(d.getMilliseconds(), 3);
    case 'L':
      var m = d.getMilliseconds();
      if (m > 99) m = Math.round(m / 10);
      return zeroize(m);
    case 'tt':
      return d.getHours() < 12 &#63; 'am' : 'pm';
    case 'TT':
      return d.getHours() < 12 &#63; 'AM' : 'PM';
    case 'Z':
      return d.toUTCString().match(/[A-Z]+$/);
      // Return quoted strings with the surrounding quotes removed   
    default:
      return $0.substr(1, $0.length - 2);
    }
  });

document.writeln(date);
//Thu Jan 08 2015 01:25:53 GMT+0800 (中国标准时间)

方法五：

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 &#63; (this.getYear() % 100).toString() : '0' + (this.getYear() % 100));
str = str.replace(/MM/, (this.getMonth() + 1) > 9 &#63; (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1));
str = str.replace(/M/g, (this.getMonth() + 1));

方法七：

/*
1、< 60s, 显示为“刚刚”
2、>= 1min && < 60 min, 显示与当前时间差“XX分钟前”
3、>= 60min && < 1day, 显示与当前时间差“今天 XX:XX”
4、>= 1day && < 1year, 显示日期“XX月XX日 XX:XX”
5、>= 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 < 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;
}

是不是第七种更加的个性化一些呢，个人推荐这种
