JavaScript에서 PHP str_replace와 동등한 작업을 수행하려면 어떻게해야합니까?

Question

JavaScript에서 대소 문자를 구분하는 문자열 대체를 수행하려면 어떻게해야합니까? 나는 PHP의 str_replace과 비슷한 것을 찾고있다.

var text = "this IS some sample text that is going to be replaced"; 
var new_text = replace_in_javascript("IS", "is not", text); 
document.write(new_text); 

는

this is not some sample text that is going to be replaced 

내가 모든 발행 수를 교체하고 싶습니다 제공해야합니다.

var str = 'is not'; 
str = str.replace(/IS/g, 'something'); // won't replace "is"

Answer 1

당신은 정규 표현식을 사용할 수 있습니다.

대/소문자를 구분하지 않으려면 i 플래그 /is/gi을 추가하십시오. PHP 함수와 정확히 같은
