angular - Incorrect display of the 'Selection confirmation' modal in case of an error during portfolio search -

admin管理员组

文章数量:1404949

On the portfolio selection page, I can either enter an account number or input a name.

When I enter an account number 979-9638403-03 and then click on the Search button

A modal is correctly displayed with the client's data

My problem

If the user's account is incorrect, for example 123-4

Another modal displays that the input is incorrect.

For now, everything is fine, but when I close the modal.

The Selection confirmation modal appears, and it bothers me a lot!

In fact, the second modal should not appear if there is an error.

I think the problem seems to be here?

...
const modalRef = this.modalService.show(SelectPortfolioResultModalComponent, {
  ...NOT_CLOSABLE_MODAL_OPTIONS,
  class: "modal-dialog-centered modal-lg",
  ariaLabelledBy: "modal-error-title",
  initialState: {
    isLoading: true,
  },
});
...

Here is the full code

export class SelectPortfolioComponent implements OnDestroy {
  private unsubscribe$ = new Subject<void>();
  search = new SelectPortfolioModel();
  account: number;

  constructor(
    private service: SelectPortfolioService,
    private modalService: BsModalService,
    private router: Router
  ) {}

  ngOnDestroy(): void {
    this.unsubscribe$.next();
    this.unsubscribe$plete();
  }

  submit(): void {
    const modalRef = this.modalService.show(
      SelectPortfolioResultModalComponent,
      {
        ...NOT_CLOSABLE_MODAL_OPTIONS,
        class: "modal-dialog-centered modal-lg",
        ariaLabelledBy: "modal-error-title",
        initialState: {
          isLoading: true,
        },
      }
    );

    modalRef
      .content!.selectedPortfolio.pipe(takeUntil(this.unsubscribe$))
      .subscribe((val: SelectPortfolio | undefined) => {
        if (val) {
          this.service
            .selectPortfolio(val)
            .pipe(takeUntil(this.unsubscribe$))
            .subscribe(() => {
              this.router.navigate(["/portfolio/valorisation"]);
            });
        }
        modalRef?.hide();
      });

    this.service
      .getPortfolios(this.search)
      .pipe(takeUntil(modalRef.content!.selectedPortfolio))
      .subscribe((res) => {
        if (modalRef) {
          modalRef.content!.portfolios = res.PTF;
          const noResults = res.RETURNLIST.find(
            (item) => item.CODE === ApiResponseCodeEnum.Sch00
          );
          if (noResults) {
            modalRef.content!.errorMessage = noResults.TEXTE;
          }
          modalRef.content!.isLoading = false;
        }
      });
  }
}

I think the previous subscriptions are still existing, which might be causing the double popup issue, it could be due to the usage of HTML with same id, name or something else. Or due to the observables being still active even when the modal gets destroyed.

Try take(1) instead of takeUntil which completes on first emission.

  submit(): void {
    ...
    modalRef
      .content!.selectedPortfolio.pipe(take(1))
