이 기사에서는 예제 코드를 통해 체크박스 기능을 표시하는 jQuery Easyui Treegrid 방법을 소개합니다. 코드가 간단하고 이해하기 쉽고, 매우 좋으며, 필요한 친구가 참고할 수 있습니다.

다음은 다음과 같습니다. 아래 사진의 글을 통해 소개합니다. Treegrid를 구현하는 방법은 무엇인가요?

요구 사항: 동적 로딩; 패키지 라이브러리/또는 미러를 표시하기 위한 정리 유형 판단(열이 다르며 미러 열이 4개임) 확인란을 선택하면 후속 확인란이 선택 취소됩니다. 상태.

다음은 특정 코드입니다.

1, Treegrid 초기화, (여러 유형 열이 있는데, 이는 백엔드 직원이 제공한 필드 이름이지만 여러 유형을 만들고 싶지는 않지만... 땀)
