페이징 효과를 구현해야 하는 프로젝트라서 jQuery 플러그인 라이브러리에서 찾아보았지만 원하는 효과를 찾을 수 없어 페이징 구성요소를 직접 캡슐화했습니다.
초기화 시 프로토타입을 기반으로 설정된 페이징 템플릿을 주로 기반으로 한 다음 동적 이벤트를 바인딩하여 DOM을 새로 고치는 페이징 효과를 얻습니다.

노출되는 인터페이스는 다음과 같습니다.
1.container: DOM 컨테이너, default.page
2.setPos: DOM에 배치된 HTML 위치, 기본 body
3.totalPages: 기본 페이지 수, 기본 null
4.totalLists: 기본 총 데이터 개수, 필수, 기본값 null
5.initPage: 현재 페이지, 기본 첫 페이지
6.inputVal: 점프 페이지, 기본 첫 페이지
7.callBack : 실행할 콜백 함수 , 필수, 기본값 null
