同一输入 Angular11 中的 FormControl 和 FormControlName

如何解决同一输入 Angular11 中的 FormControl 和 FormControlName

我处理了我的代码，因为我正在尝试使用 formControl 进行自动完成，但是当您选择某些内容到我的表单组数组时，我需要将这些数据带入。我想知道是否存在一种方法，我可以将 formControl 用于过滤我的自动完成和 formControlName 用于获取数据，谢谢，这是我的代码：

        newArticle: FormControl = this.fb.control('',Validators.required);
      registerForm: FormGroup = this.fb.group({
        itemRows: this.fb.array([
          this.fb.group({
            article: [,Validators.required],quantity: [,price: [,discount: [,subtotal: [0,warehouse: ['',})
        ]),tax: [,date: [this.datetoday,Validators.required]
      });
  get rowsArr() {
    return this.registerForm.get('itemRows') as FormArray;
  }

ngOnInit(): void {
    this.filteredOptionsArticle = this.newArticle.valueChanges
      .pipe(
        startWith(''),map(value => typeof value === 'string' ? value : value.descripcion),map(descripcion => descripcion ? this._filtera(descripcion) : this.ArticleList.slice())
      );
    this.article.listArticles().subscribe((result) => {
      this.ArticleList = result;
    })
}

  addNewRow() {
    //if( this.registerForm.invalid ) { return; }
    const newRow = this.fb.group({
      article: [,warehouse: ["",Validators.required]
    })
    this.rowsArr.push(newRow);
  }
  deleteRow(rowIndex: number) {
    const control = <FormArray>this.registerForm.controls['itemRows'];
    if (control != null) {
      this.totalRow = control.value.length;
    }
    if (this.totalRow > 1) {
      control.removeAt(rowIndex);
    } else {
      alert('you need to write all')
    }
  }

private _filtera(name: string): IArticles[] { const filterValue = name.toLowerCase(); 返回 this.ArticleList.filter(option => option.descripcion.toLowerCase().indexOf(filterValue) === 0); }

还有我的 HTML：

    <form [formGroup]="registerForm">
