JavaScript Date formatting method Rollup _javascript Tips

Method One:

An extension to date that converts date to a string
/month (M) in the specified format, days (d), hours (h), minutes (M), seconds (s), quarter (q) can be used in 1-2 placeholders, 
//year (Y) can be 1-4 placeholders, milliseconds (s) can only be 1 Placeholder (1-3 digits) 
//Example: 
//(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,//month 
    "d+": this.getdate (),//day 
    "h+": this.gethours (),//hour 
    " m+ ": this.getminutes (),// 
    " s+ ": This.getseconds (),//sec 
    " q+ ": Math.floor ((This.getmonth () + 3)/3),//Quarter 
    "S": this.getmilliseconds ()//Millisecond 
  };
  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]): (("+ o[k]"). substr (("" + o[k). length));
  return FMT;
}

Call Mode:

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

Method Two:

<script language= "javascript" type= "Text/javascript" > <!--/** * The extension of date to the specified format of String * Month (M), day (d), 12 small (h), 24 hours (h), minutes (m), SEC (s), Week (E), quarter (q) can use 1-2 placeholder * year (y) can use 1-4 placeholders, milliseconds (s) can only use 1 placeholders (1-3 digits) * Eg: * (new Date ()). Pat Tern ("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 II 20:09:04 * ( New Date ()). Pattern ("Yyyy-mm-dd EE hh:mm:ss") ==> 2009-03-10 Tuesday 08:09:04 * (new Date ()). Pattern ("Yyyy-mm-dd EEE hh:    
Mm:ss ") ==> 2009-03-10 Tuesday 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,//month "d+": This.getdate () ,//day "h+": this.gethours ()%12 = = 0? 12:this.gethours ()%12,//hr "h+": this.gethours (),//Hour "m+": this.getminutes (),//"s+": this.   Getseconds (),//sec "q+": Math.floor (This.getmonth () +3)/3),//Quarter  
  "S": this.getmilliseconds ()//millisecond}; var week = {"0": "/u65e5", "1": "/u4e00", "2": "/u4e8c", "3": "/u4e09", "4": "/u5     
  6db "," 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>2?)     
  "/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)?     
    (O[k]): (("+ o[k]"). substr (("" + o[k). length));     
} return FMT;   
var date = new Date ();
Window.alert (Date.pattern ("Yyyy-mm-dd hh:mm:ss"));
 --> </script>

Method Three:

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 (?: D {1, 4} | m {1, 4} | yy (?: yy)? | ([HHMSTT])/1? | [Llz])
    /b/g, function ($) {switch ($) {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 [' Out of the ', ' Feb ', ' Mar ', ' Apr ', ' may ', ' June ', ' may ', ' 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 >) m = Math.Round (M/10);
    Return Zeroize (m); Case ' TT ': Return d.gethours () < 12?
    ' Am ': ' PM '; Case ' TT ': Return d.gethours () < 12?
    ' 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);
}
  });

Method Five:

Date.prototype.Format = function (formatstr) {var str = formatstr; var Week = [' Day ', ' one ', ' two ', ' three ', ' four ', ' five ', ' Six ']; str = Str.replace (/yyyy|
yyyy/, This.getfullyear ()); str = str.replace (/yy| yy/, (this.getyear ()%) > 9?
(This.getyear ()%). 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}

Method Six:

Date.prototype.Format = function (formatstr) {var str = formatstr; var Week = [' Day ', ' one ', ' two ', ' three ', ' four ', ' five ', ' Six ']; str = Str.replace (/yyyy|
yyyy/, This.getfullyear ()); str = str.replace (/yy| yy/, (this.getyear ()%) > 9?
(This.getyear ()%). 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?

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}

Method Seven:

 * * 1, < 60s, displayed as "just" 2, >= 1min && < min, showing the current time difference "xx minutes ago" 3, >= 60min && < 1day, showing the current time difference "Today xx:xx" 4, >= 1day && < 1year, show the date "xx month xx day xx:xx" 5, >= 1year, show the specific date "XXXX" XX month XX day xx:xx "/function TimeFormat (time) {var date = new Date (time), curdate = new Date (), year = Date.getfullyear (), M Onth = Date.getmonth () + ten, day = Date.getdate (), hour = Date.gethours (), minute = Date.getminutes (), curyear = curdate.g
 
Etfullyear (), Curhour = Curdate.gethours (), timestr; if (Year < curyear) {timestr = yearly + ' years ' + month + ' month ' + day + ' days ' + Hour + ': ' + Minute;}
 
else{var pasttime = curdate-date, pasth = pasttime/3600000; if (Pasth > Curhour) {timestr = month + ' month ' + day + ' days ' + Hour + ': ' + Minute;} else if (pasth >= 1) {timestr = ' today ' + Hour + ': ' + minute + ' min ';} else{var pastm = curdate.getminutes ()-minute; if (Pastm > 1) {timestr = pastm + ' minutes ago ';}
else{timestr = ' just ';}}
return timestr; }

is not the seventh kind of more personalized, personally recommended this
