dataexporter를 클릭하면 데이터 테이블을 내보내는 대신 입력 필드의 유효성을 검사합니다.

Question

공급 업체 추가 및보기 용 코드를 작성하고 있습니다. 그러나 문제는 다른 형식으로 테이블을 내보내는 dataexporter를 추가 한 것입니다. dataexporter를 클릭하면 datatable을 내보내는 대신 inpuut 필드의 유효성을 검사합니다. 아래 코드 참조

도와주세요. 나는 언젠가 이것을 고치고 같은 결과를 얻으려고 노력해왔다. 감사합니다

JSF에는 6 개의 라이프 사이클 단계가 있습니다. 그 중 하나가 Process Validation 단계입니다. 이 단계에서는 입력 구성 요소 (예 : 입력 필드)의 유효성 검사가 수행됩니다. 귀하의 경우에는 유효성 검사를 원하지 않습니다. Render Response 단계가 생략됩니다 때까지이는 Apply Request Values 후 모든 수명주기 단계를 설정으로

<h:commandLink immediate="true"> 
    <p:graphicImage value="/images/excel.png" /> 
    <p:dataExporter type="xls" target="singleTB" fileName="report" pageOnly="true"/> 
</h:commandLink> 

: 그래서 당신이 무엇을로 CommandLink는 구성 요소에 immediate 속성을 추가한다.
