Question

import { FormGroup } from '@angular/forms';

export class MasterVendorFormContactComponent implements OnInit {
  @Input() formContactGroup: FormGroup;
// rest of the code 
}


<fieldset [formGroup]="formContactGroup" class="master-vendor-form-contact">
  <md-input-container class="master-vendor-form-contact__phone"
                      [dividerColor]="formContactGroup.controls.phone?.valid ? 'default' : 'warn'">
    <input mdInput placeholder="Enter phone" formControlName="phone">
    <md-hint align="end"
             *ngIf="!formContactGroup.controls.phone?.valid">
      Vendor phone number must be in (XXX) XXX-XXXX format
    </md-hint>
  </md-input-container>
  <!-- Rest of the code -->
</fieldset>

在编译此代码时会出现以下错误：

angular_app/src/$$_gendir/app/master-vendors/master-vendor-form-contact/master-vendor-form-contact.component.ngfactory.ts (465,73): Property 'phone' does not exist on type '{ [key: string]: AbstractControl; }'.

我尝试过这种方法：

请勿使用form.controls.controlName，请使用form.get（'controlName'）

但是我在这里有formContactGroup，所以它似乎不适合我。

有两个选项，您可以更新到最新的打字稿版本。由于version 2.2，它们允许带有字符串索引签名的类型的点符号。

或者您可以更改模板，这更有意义，因为这是正确的方法:) documentation：

<md-input-container [dividerColor]="formContactGroup.get('phone').valid ? 'default' : 'warn'">

类型'{[key：string]：属性'xxxx'不存在：AbstractControl; }”
