Автозаполнение формы formInit не заполняет мое значение

0 голосов
/ 23 мая 2019

у меня есть эта автозаполнение внутри формы 

<input type="text" placeholder="Pilih Bank" matInput [matAutocomplete]="auto" formControlName="bankName">
<mat-autocomplete #auto="matAutocomplete" (optionSelected)='onChangeBank()' [displayWith]="displayFn">
  <mat-option>Pilih Bank</mat-option>
  <mat-option *ngFor="let option of filteredOptions | async" [value]="option">
    {{option.bankName}}
  </mat-option>
</mat-autocomplete>

когда я пытаюсь initForm() и у пользователя есть значение для bankName, я хочу заполнить formControlName значением пользователя, но оно все равно не изменится.

это внутри моего `TS

Итак, мне было обещано, что я обновлю эту ветку, если найду проблему, и вот эта моя проблема.извините за позднее обновление.тип данных, который я получаю в initForm () - это строка, а данные, которые я отправляю, когда выбираю из параметра, - это объект.поэтому мне нужно дать некоторые условные .. 

displayFn(user?: User) {
 if ((typeof user) === 'string') {
  return user
 }
 return user ? user.bankName : '';
}

Вы можете использовать patchValue или setValue для установки значения формы из TS

TS 

if (_.hasIn(this.profileData, 'borrower.bankAccount.bankName')) {
//By SetValue
this.form.controls['bankName'].setValue(this.profileData.borrower.bankAccount.bankName);
//By PatchValue
this.form.controls['bankName'].patchValue(this.profileData.borrower.bankAccount.bankName);}

Я просто проверяю весь ваш кодВы устанавливаете значение перед инициализацией формы 

first initialize the form

this.form = this.formBuilder.group({ 
   bankName : [bankName, Validators.required], 
   rekNo : [rekNo, [Validators.required, Validators.maxLength(20)]], 
   bankAccount : [bankAccount, Validators.required],
   identityImg : [identityImg, Validators.required],
   taxImg : taxImg, paySlipImg : paySlipImg, 
   identityImgURL: identityImgURL, 
   taxImgURL : taxImgURL, 
   paySlipImgURL : paySlipImgURL
 });

// then set the value 
this.form.controls['bankName'].setValue(this.profileData.borrower.bankAccount.bankName);
...
