Date.prototype.toISOString()

toISOString() 메서드는 단순화한 확장 ISO 형식(ISO 8601)의 문자열을 반환합니다. 반환값은 언제나 24글자 또는 27글자(각각 YYYY-MM-DDTHH:mm:ss.sssZ 또는 ±YYYYYY-MM-DDTHH:mm:ss.sssZ)입니다. 시간대는 언제나 UTC이며 접미어 "Z"로 표현합니다.

구문

dateObj.toISOString()

반환 값

주어진 날짜를 국제표준시 기준 ISO 8601 형식으로 표현한 문자열.

예제

toISOString() 사용하기

아래 예제는 비표준 문자열의 분석을 포함하고 있어 비 Mozilla 브라우저에서는 올바르게 작동하지 않을 수 있습니다.

const today = new Date('05 October 2011 14:48 UTC');

console.log(today.toISOString()); // Returns 2011-10-05T14:48:00.000Z

폴리필

toISOString은 ECMA-262 제5판에 표준으로 자리잡았습니다. 아직 지원하지 않는 환경에서는 다음 코드를 추가해 대체할 수 있습니다.

if (!Date.prototype.toISOString) {
  (function() {

    function pad(number) {
      if (number < 10) {
        return '0' + number;
      }
      return number;
    }

    Date.prototype.toISOString = function() {
      return this.getUTCFullYear() +
        '-' + pad(this.getUTCMonth() + 1) +
        '-' + pad(this.getUTCDate()) +
        'T' + pad(this.getUTCHours()) +
        ':' + pad(this.getUTCMinutes()) +
        ':' + pad(this.getUTCSeconds()) +
        '.' + (this.getUTCMilliseconds() / 1000).toFixed(3).slice(2, 5) +
        'Z';
    };

  }());
}
