자바스크립트 함수 중 alert 이라는 함수를 override 하여
system modal window 가 아닌 layer 디자인을 통해 alert window를 만들어 사용할 수 있습니다.
(window.confirm 도 바꿀 수 있겠죠.. ㅎㅎ )

system alert 과 같은 형태의 효과를 내기 위해서는 몇가지 더 추가 되어야 할 사항들이 있습니다.
alert window가 발생된 시점에 content의 모든 영역에 click을 방지 하기 위해 투명 layer로 차단해줘야 겠죠
그외에도 몇가지 더 추가 해야 할 거 같습니다.
