다음 코드를 작성하면 지난 달에 12 개월을 더한 월이 생성됩니까?

Question

다음 코드는 일정 방식으로 올해과 형식 그것의 현재 월을 취

let curYear = 2017 
let curMonth = 11 
let result = [] 
let firstDayOfMonth = new Date(curYear, curMonth, 1) 
let lastDayOfMonth = new Date(curYear, curMonth, getLastDayOfMonth(curMonth)) 

result.unshift(firstDayOfMonth) 
for (let d = prevDate(firstDayOfMonth); d.getDay() !== 6; d = this.prevDate(d)) { 
    result.unshift(d) 
} 
for (let d = nextDate(firstDayOfMonth); d <= lastDayOfMonth; d = nextDate(d)) { 
    result.push(d) 
} 
for (let d = nextDate(lastDayOfMonth); d.getDay() !== 0; d = nextDate(d)) { 
    result.push(d) 
} 

console.log(JSON.stringify(result)) 

function nextDate (d) { 
    let result = new Date(d.valueOf()) 
    result.setDate(d.getDate() + 1) 
    return result 
} 

function prevDate (d) { 
    let result = new Date(d.valueOf()) 
    result.setDate(d.getDate() - 1) 
    return result 
} 

function getLastDayOfMonth (m) { 
    let result = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31] 
    if (leapYear) { 
    result[1] = 29 
    } 
    return result[m] 
} 

function leapYear() { 
    if (curYear % 100 === 0) { 
    return curYear % 400 === 0 
    } else { 
    return curYear % 4 === 0 
    } 
} 

출력 :

?

예를 들어 (오른쪽에서 왼쪽으로 읽기) :

(and so on) ... 2017-10-05, ... 2017-11-05, ... 2017-12-05, ... , 2018-01-05]

참고 : 나는 또한 Moment.js/Luxon 대안을 환영

Answer 1

// use moment.js 
let curDate = moment();  
let newDate = moment().add(12, 'month'); 
let dateValues = []; 

while (newDate > curDate) { 
    dateValues.push(curDate.format('YYYY-MM-DD')); 
    curDate.add(1,'month'); 
}
