자바스크립트 날짜 구문 분석()

실시예 1

let ms = Date.parse("March 21, 2012");

정의 및 사용

parse() 날짜 문자열을 구문 분석하고 1970년 1월 1일 이후의 시차를 반환합니다.

parse() 시간 차이를 밀리초 단위로 반환합니다.

실시예 2

1970년 1월 1일에서 2012년 3월 21일 사이의 연도 수를 계산합니다.

// Calculate milliseconds in a year
const minute = 1000 * 60;
const hour = minute * 60;
const day = hour * 24;
const year = day * 365;

// Compute years
const d = Date.parse("March 21, 2012");
let years = Math.round(d / year);

브라우저 지원

parse() ECMAScript1(ES1) 기능입니다.

ES1(JavaScript 1997)은 모든 브라우저에서 완벽하게 지원됩니다.
