Ich habe ein Formulararray in einem Formbuilder und ändere Formulare dynamisch, dh beim Klicken Daten aus Anwendung 1 laden usw.
Das Problem, das ich habe, ist, dass alle Daten geladen werden, aber die Daten im Formulararray bleiben und nur die alten Elemente mit neuen verknüpfen.
Wie lösche ich dieses Formular, um nur die neuen Elemente zu haben?
Ich habe es versucht
const control2 = <FormArray>this.registerForm.controls['other_Partners'];
control2.setValue([]);
aber es funktioniert nicht.
Irgendwelche Ideen? Vielen Dank
in 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({
