JavaScript date format (JS dates formatted)

Method One: This is very good, seems to be written by Csdn's Meizz:

[JavaScript] View Plain copy//  the extension to date, converting  Date  to the string   //  month (m), Day (d), hour (h), Minute (m), Seconds (s), quarter (q)   can use  1-2  placeholders,   //  years (y) can be used with  1-4  placeholders, milliseconds (s) can only be used  1   Placeholder (is a number of  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 (),                    //hours          "m+"  : this.getminutes (),                  //         "s+" &NBSP:  this.getseconds (),                  //sec          "q+"  : math.floor ((This.getmonth () +3) /3),  //quarterly          "S"   : this.getmilliseconds ()               //milliseconds       };      &nbsP;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 Method:

[JavaScript] view plaincopy var time1 = new Date (). Format ("Yyyy-mm-dd HH:mm:ss");    var time2 = new Date (). Format ("Yyyy-mm-dd");
