Customizing Angular Forms: Set formcontrol value to a different value when selecting from autocomplete suggestions

How can I mask input for formControl name in HTML? When the autocomplete feature is displayed, only the airport's name is visible. After users select an airport, I want to show the airport's name in the input value but set the entire airport object as the formControl value. This way, when I perform a search, I have access to more than just a string for data retrieval.

<mat-form-field>
    <input
      matInput
      formControlName="departure_airport"
      #el_departure_input
      class="[ flight-travel-form__airport__input ][ typography-sub-heading ]"
      value=""
      placeholder="Departure"
      [matAutocomplete]="auto"
    />
  </mat-form-field>

  <mat-autocomplete #auto="matAutocomplete">
    <mat-option *ngFor="let airport of active_search_suggestions$ | async" [value]="airport" class="ten-autocomplete">
      {{ airport.name.toLowerCase() }}
      <br>
      <span class="typography-small-text">{{ airport.iata_code }}</span>
      <div *ngIf="airport.object_type === 'airport_group'"> Any Airport</div>
    </mat-option>
  </mat-autocomplete>
</div>

Answer №1

To access the complete airport object, all you need to do is implement

(onSelectionChange)=selectedAirport(airport)
for each <mat-option>
