patchValue formArray 3级Angular 8

Question

我有一个FormGroup：

this.rooms = new FormGroup({
      room:  this._fb.array([
        this._fb.group({
          adultQuantity: [2],
          childQuantity: [0],
          childrenAges: this._fb.array([
            new FormControl('', Validators.required)
          ])
        })
      ])
    });

数据从API获取：

room: [{
    adultQuantity: 2,
    childQuantity: 1,
    childrenAges: [3,5]
},
{
    adultQuantity: 2,
    childQuantity: 2,
    childrenAges: [3,2,9]
}]

如何将数据修补到FormGroup会议室。
抱歉，我英语不好。
谢谢大家。

Answer 1

您可以像这样修补表格，

[0] => thisisline = aline
