asp. 정보net 가짜 페이지 삭제 작업 에세이
내가 달성해야 할 효과는 삭제 단추를 눌렀을 때 원래 그 페이지였고, 삭제 후에도 그 페이지였다.
프로젝트는 이미 검수했기 때문에 나는 너무 크게 바꿀 수 없다.나는 인터넷 페이지에서 오랫동안 찾았고, 해결 방안도 많았지만, 모두 그다지 적합하지 않았다.
이 시스템은 데이터가 많지 않기 때문에 가짜 페이지를 사용하고 Repeater 컨트롤을 사용했다. 백엔드에서 데이터베이스에 있는 데이터를 모두 조회하여 Repeater에 넣었다. jquery를 통해 페이지를 나눈다. 다음은 내가 쓴 간단한 테스트 항목이다.
프론트 데스크 코드는 다음과 같습니다.
