search() 메서드는 정규 표현식과  이 {{jsxref("String")}}  객체간에 같은 것을 찾기
+ 위한 검색을 실행한다.

+ + + +

구문

+ +
str.search(regexp)
+ +

매개변수

+ +
+
regexp
+
정규 표현식 객체.  non-RegExp 객체 obj 가 전달되면,  그것은  new RegExp(obj) 을 이용하여 {{jsxref("RegExp")}} 으로 암묵적으로 변환된다.
+
+ +

반환 값

+ +

정규표현식과 주어진 스트링간에 첫번째로 매치되는 것의 인덱스를 반환한다.
+ 찾지 못하면 -1 를 반환한다.

+ +

설명

+ +

When you want to know whether a pattern is found and also its index in a string use search() (if you only want to know if it exists, use the similar {{jsxref("RegExp.prototype.test()", "test()")}} method on the RegExp prototype, which returns a boolean); for more information (but slower execution) use {{jsxref("String.prototype.match()", "match()")}} (similar to the regular expression {{jsxref("RegExp.prototype.exec()", "exec()")}} method).

+ +

예

+ +

search()를 이용하기

+ +

The following example searches a string with 2 different regex objects to show a successful search (positive value) vs. an unsuccessful search (-1)

+ +
var str = "hey JudE";
+var re = /[A-Z]/g;
+var re2 = /[.]/g;
+console.log(str.search(re)); // returns 4, which is the index of the first capital letter "J"
+console.log(str.search(re2)); // returns -1 cannot find '.' dot punctuation
