테이블의 "닫을 때" 이벤트 핸들러 내에서 해당 테이블에 대한 참조를 얻으려면 어떻게 해야 합니까?

안녕!

테이블의 On Close 문 내에서 해당 테이블에 대한 참조를 얻는 데 도움이 필요합니다.

간단한 스크립트가 있습니다. "열기" 버튼이 있는 GUI가 있는데, 이 버튼을 누르면 데이터 테이블이 열리고, 테이블 목록이 있는 콤보 박스도 있습니다.

또한 테이블 이름을 키로, 테이블 참조를 값으로 하는 연관 배열을 사용하여 테이블들을 관리합니다.

이 스크립트에서 유지 관리해야 하는 기존 네임스페이스가 몇 개 있습니다. 콤보 상자에서 테이블을 제거하기 위해 OnClose 문에서 Eval(Eval Expr(Expr()))라는 방법을 사용하고 있습니다. 하지만 이 방법은 연관 배열에서 테이블을 제거하는 데는 작동하지 않습니다.

Function({this}, _dt = ((this << Child) << Get Data Table))을 사용하는 또 다른 트릭이 있습니다. 이 함수는 데이터 테이블에 대한 참조를 가져오는 데는 제대로 작동하지만, Eval(Eval Expr(Expr()))) 안에 넣으면 작동을 멈춥니다.

I tried to get the reference to the table separately, but looks like I don't know how Function({this}, ) works. How do I assign a result of this function to a variable?&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;/P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;br /&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;Anyways, here's the latest iteration of my script, please help me tweak it to make it work.&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;/P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;

보통 저는 On Close 이벤트에서 테이블 이름/참조를 평가합니다. <를 사용할 수도 있습니다. 이것은 데이터 테이블 창 을 참조하는 것입니다(스크립트 색인에 예제가 있습니다).

테이블 목록을 관리하려면 `Subscribe To Data Table List()` 함수를 사용하는 것도 고려해 볼 수 있습니다. 저는 이 함수를 사용하여 JMP 스크립트 편집기에서 볼 수 있는 테이블 목록과 매우 유사한 기능을 구현했으며, 이름 변경/테이블 폐쇄/개설을 처리할 수 있습니다(다만 구현이 더 복잡하고 몇 가지 문제점이 있습니다).

무슨 이유인지 모르겠지만, 이 사용 사례에서는 Eval(Eval Expr(Excpr)))에 테이블을 포함시키는 것이 잘못되었다고 판단했습니다. 다시 작성해 보겠습니다.
