자바스크립트 문자열 split()

단어 나누기:

let text = "How are you doing today?";
const myArray = text.split(" ");

단어를 나누고 두 번째 단어를 반환합니다.

let text = "How are you doing today?";
const myArray = text.split(" ");
let word = myArray[1];

공백을 포함한 문자 분할:

const myArray = text.split("");

제한 매개변수를 사용합니다.

const myArray = text.split(" ", 3);

아래에 더 많은 예가 있습니다.


정의 및 사용

split()메서드는 문자열을 하위 문자열 배열로 분할합니다.

split()메서드는 새 배열을 반환합니다.

split()메서드는 원래 문자열을 변경하지 않습니다.

(" ")가 구분 기호로 사용되는 경우 문자열은 단어 간에 분할됩니다.


통사론

string.split(separator, limit)

매개변수

Parameter Description
separator Optional.
A string or regular expression to use for splitting.
If omitted, an array with the original string is returned.
limit Optional.
An integer that limits the number of splits.
Items after the limit are excluded.

반환 값

유형 설명
정렬분할된 값을 포함하는 배열입니다.


더 많은 예

문자열을 문자로 분할하고 두 번째 문자를 반환합니다.

const myArray = text.split("");

문자를 구분 기호로 사용:

const myArray = text.split("o");

구분자 매개변수가 생략되면 원래 문자열이 있는 배열이 반환됩니다.

const myArray = text.split();

브라우저 지원

split()ECMAScript1(ES1) 기능입니다.

ES1(JavaScript 1997)은 모든 브라우저에서 완벽하게 지원됩니다.
