How to extract the chosen option from a bound list within an Angular application

Our goal is to avoid using 2-way binding in our component setup:

<select type="text" formControlName="region" (change)="regionChanged($event)">
      <option *ngFor="let region of regionsDDL" [ngValue]="region">{{region.name}}</option>
    </select>

The form is created reactively using the form builder:

this.fb.group({
.
region:...
.
});

In the event handler, we aim to retrieve the entire object linked to the selected option. Is it safe to access the form group value like this?

regionChanged($event) {
  let selectedRegion = this.basicInfoForm.controls["region"].value;
}

Or is there a chance that the form control value may not be updated before the (change) event occurs?

Answer №1

Be sure to assign a ngModel and utilize the ngModelChange() event

<select type="text" formControlName="region" [ngModel]="someValue" (ngModelChange)="regionChanged($event)">
              <option *ngFor="let region of regionsDDL" [ngValue]="region">{{region.name}}</option>
            </select>
