[javascript] setTimeout, setInterval 파라미터 버그

avatar
(Edited)
  • IE 9 이하로 setTimeout 선언시에 파라미터 값을 던지면 값이 undefined 로 넘어온다.

1. 버그 상황

setTimeout( fncName, duration, param1, param2 );

2. 대응 코드

  • 아래와 같이 익명함수로 하나 감싸서 던지거나 새로운 함수를 지정하여 던져서 실행하면 문제가 없다.
setTimeout(function() {
  fncName( param1, param2 );
}, duration);

3. 참고

kr settimeout setinerval ie9 busy
