У меня огромный список counties
и я хочу реализовать функцию автозаполнения. Я использую ту же форму для add
нового клиента или update
существующего клиента.
Теперь проблема в том, что при добавлении нового клиента моя программа работает отлично, но когда я обновляю ее В раскрывающемся списке округа он показывает countyId
вместо name
. Как этого добиться? см. изображения в следующем порядке:
Схема округа имеет вид
{
countyId: number;
name:string
}
Я пытаюсь использовать следующий код в html
<mat-form-field appearance="outline" fxFlex="50" class="pr-4">
<mat-label>County</mat-label>
<input type="text" placeholder="County" name="" matInput formControlName="countyId" [matAutocomplete]="auto">
<mat-autocomplete autoActiveFirstOption #auto="matAutocomplete">
<mat-option *ngFor="let county of filteredCounties | async" [value]="county.name">
{{county.name}}
</mat-option>
</mat-autocomplete>
</mat-form-field>
и в моем файле компонента
