使用jQuery为日期添加月份

FechaInicio year , month 和 day Meses .

// Magical parsing of `FechaInicio` here
var year = 2010, month = 9, day = 14;
// The value of `meses`
var meses_mas = 3;

var future_date = new Date(year, month + meses_mas, day);

console.log(future_date);

你最终会得到 Wed Apr 14 2011 00:00:00 GMT-0700 (PST)

此外作为旁注, Date

var startDate = parseDate();
var monthsToAdd = getMonthsToAdd();

while (startDate.getMonth() + monthsToAdd > 11) {
  startDate.setFullYear(startDate.getFullYear() + 1);
  monthsToAdd - 11;
}

startDate.setMonth(startDate.getMonth() + monthsToAdd);

        var numofMonthtoAdd = 5; //number of month you may want to add

        var beginDate = new Date();
        var month = (parseInt(beginDate.getMonth()) + parseInt(numofMonthtoAdd )) % 12;
        var year = (parseInt(beginDate.getMonth()) + parseInt(numofMonthtoAdd )) / 12;
        beginDate.setMonth(month);
        beginDate.setFullYear(parseInt(beginDate.getFullYear()) + year );
        return beginDate;
