How to convert into date fo

Answer 1

Real short hand:

Date.prototype.yyyymmdd = function() {
     var yyyy = this.getFullYear().toString();
     var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
     var dd  = this.getDate().toString();
     return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]); // padding
};

var s='/Date(1399739515000)/';
var regex = /(\d+)/g;
alert(new Date(parseInt(s.match(regex))).yyyymmdd());
