向formGroup添加新属性的最佳实践

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

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

@Component({
  // 组件的其他配置
})
export class YourComponent implements OnInit {
  formGroup: FormGroup;

  constructor(private formBuilder: FormBuilder) { }

  ngOnInit() {
    this.formGroup = this.formBuilder.group({
      // 其他表单控件
      newAttribute: new FormControl()
    });
  }
}

<form [formGroup]="formGroup">
  <!-- 其他表单控件的HTML代码 -->
  <input type="text" formControlName="newAttribute">
</form>
