JavaScript to implement the method of adding days in a given time _javascript skills

The examples in this article describe how JavaScript implements the number of days added for a given time. Share to everyone for your reference, specific as follows:

/** * Time Add processing function * @param date time to calculate (xxxx-xx-xx) * @param number of days to add (integer)/function calcudate (date, plusdays) {VA
  R Datearray = Date.split ("-");
  var year = +datearray[0];
  var month = +datearray[1];
  var day = +datearray[2];
  var oriday = day; var secondmonthdays = ((year%4 = = 0 && year%100!== 0) | | | year%400 = 0)?
  29:28;
    while (plusdays>0) {oriday = Day Day = = Plusdays; Switch (month) {case 4:case 6:case 9:case 11:if (Day >) {plusdays-= (
          30-oriday) +1;
          month++;
        Day = 1;
        else {plusdays = 0;
      } break;
          Case 2:if (Day > Secondmonthdays) {plusdays-= (secondmonthdays-oriday) +1;
          month++;
        Day = 1;
        else {plusdays = 0;
      } break;
          Default:if (Day >) {plusdays-= (31-oriday) +1;
          Day = 1;
        month++;
    } else {      plusdays = 0;
      } if (month>12) {month = 1;
    year++;
} Return to Createtimestring (year, month, day);

 }

Of course, in addition to this approach, there are other, similar to the new date parameters such as the solution, which is a kind of
