How to call a function after form submit in Angular 12-CodePudding

I have a component called ListScheduleComponent it has a function that opens a mat-dialog with CreateScheduleComponent view:

  handleDateSelect(selectInfo: DateSelectArg) {
    this.fileNameDialogRef = this.dialog.open(CreateScheduleComponent, {
      data: {
        startdate: this.datePipe.transform(selectInfo.start, 'yyyy-M-dd'),
        enddate: this.datePipe.transform(selectInfo.end, 'yyyy-M-dd'),
      },
    });
  }

and a function that loads all events:

getAllEvents(){
  //Events are loaded and displayed in the calendar
}

so it looks like this:

Now in my CreateScheduleComponent I have a submit function:

onSubmit(): void {
    this.calendarService
      .createNewEvent(this.eventForm.value)
      .subscribe((response) => {
        if (response.statuscode===201) {
          //Call getAllEvents();
        } else {
          console.log(response.message);
        }
      });
  }

I know how to close this dialog just by this.dialogRef.close() but my problem is, How can I call the getAllEvents(); function from ListScheduleComponent component after form onSubmit()?

CodePudding user response：

Subscribe afterClosed() method on dialog and do your stuff here which you want to do after dialog has been closed -

handleDateSelect(selectInfo: DateSelectArg) {
    this.fileNameDialogRef = this.dialog
      .open(CreateScheduleComponent, {
        data: {
          startdate: this.datePipe.transform(selectInfo.start, "yyyy-M-dd"),
          enddate: this.datePipe.transform(selectInfo.end, "yyyy-M-dd"),
        },
      })
      .afterClosed()
      .subscribe((res) => {
        // call getAllEvents() here
      });
  }
