 Date.prototype.format = function (format)

}  
 if (/ (y +) /. test (format)) format = format.replace (RegExp. $ 1,  . 
 (this.getFullYear () + "") substr (4 - RegExp $ 1.length.));  
 for (var k in o) if (new RegExp ("(" + k + ")"). test ( format))  
 format = format.replace (RegExp. $ 1,  
 RegExp $ 1.length == 1 o [k].?:  
 ("00" + o [k]) substr (("" + o [k]) length.)).;  
 return format;  
}  
  
  
  
  
 var unixTimestamp = new Date (value);  
 return unixTimestamp.format ('yyyy-MM-dd');

 cousin I could not understand , 
 ------ For reference only ----- ---------------------------------- 
 
 cousin I could not read,       
  
 write a javascript method  
 function (value) {  
 var unixTimestamp = new Date (value);  
 return unixTimestamp.format ('yyyy-MM-dd');  
 }  
 Take your date to wear in, what is called , returns the output is formatted date format
