자바스크립트 정규식 테스트()


예시

문자 "e"에 대한 문자열 검색:

let text = "The best things in life are free"; let pattern = /e/;
let result = pattern.test(text);

정의 및 사용

test() 메서드는 문자열의 일치 여부를 테스트합니다.

일치하는 항목을 찾으면 true를 반환하고, 그렇지 않으면 false를 반환합니다.

브라우저 지원

test()ECMAScript1(ES1) 기능입니다.

ES1(JavaScript 1997)은 모든 브라우저에서 완벽하게 지원됩니다.

통사론

RegExpObject.test(string)

매개변수 값

Parameter Description
string Required. The string to be searched

반환 값

Type Description
Boolean Returns true if it finds a match, otherwise false


더 많은 예

예시

전역 검색을 수행하고 문자열에서 "Hello" 및 "W3Schools"를 테스트합니다.

// The string:
let text = "Hello world!";

// Look for "Hello"
let pattern1 = /Hello/g;
let result1 = patt.test(text);

// Look for "W3Schools"
let pattern2 = /W3Schools/g;
let result2 = pattern2.test(text);

정규식 검색 방법

JavaScript에서 정규 표현식 텍스트 검색은 다른 방법으로 수행할 수 있습니다.

패턴 을 정규식으로 사용하는 경우 가장 일반적인 방법은 다음과 같습니다.

예시설명
text.match( 패턴 )문자열 메서드 match()
text.search( 패턴 )문자열 메서드 search()
패턴 .exec(텍스트)RexExp 메소드 exec()
패턴 .test(텍스트)RegExp 메서드 test()
