Mam tablicę formularzy wewnątrz konstruktora formularzy i dynamicznie zmieniam formularze, tj. Ładowanie danych z aplikacji 1 po kliknięciu itp.
Problem, który mam, polega na tym, że wszystkie dane są ładowane, ale dane w formarray pozostają i po prostu łączą stare elementy z nowymi.
Jak wyczyścić tę tablicę, aby mieć tylko nowe elementy.
Próbowałem tego
const control2 = <FormArray>this.registerForm.controls['other_Partners'];
control2.setValue([]);
ale to nie działa.
Jakieś pomysły? dzięki
w nginit
ngOnInit(): void {
this.route.params.subscribe(params => { alert(params['id']);
if (params['id']) {
this.id = Number.parseInt(params['id']);
}
else { this.id = null;}
});
if (this.id != null && this.id != NaN) {
alert(this.id);
this.editApplication();
this.getApplication(this.id);
}
else
{
this.newApplication();
}
}
onSelect(Editedapplication: Application) {
this.router.navigate(['/apply', Editedapplication.id]);
}
editApplication() {
this.registerForm = this.formBuilder.group({
id: null,
type_of_proposal: ['', Validators.required],
