position() / offset()
요소 위치 메서드에는 position()메서드와 offset()메서드가 있습니다. position() 메서드는 포지션 기준이 되는 요소를 기준으로 선택한 요소에서 가로/세로로 떨어진 위치와 좌표값을 반환하거나 변경할 때 사용합니다. offset() 메서드는 문서를 기준으로 선택한 요소의 가로/세로로 떨어진 위치의 좌표값을 반환하거나 변경할 때 사용합니다.
$("선택자").position().left; $("선택자").position().right; $("선택자").position().top; $("선택자").position().bottom;
$("선택자").offset().left; $("선택자").offset().top;
