angular - 在打字稿中选择嵌套的 forControl

Question

我有一个这样的表单组

this.orderForm = this._formBuilder.group({      
  vlanFormGroup: this._formBuilder.group({
    vId: ['', [Validators.required, Validators.pattern(this.positiveInteger)]],
    vName: ['', [Validators.required, Validators.pattern(this.vlanNamePattern)]],
    addVToTrunk: [''],
    trunkInterfaces: this._formBuilder.array([
      this.createAddVlanToTrunkMember()
    ])
  })
});    

我正在尝试像这样获得 vId

let vId = component.orderForm['vlanFormGroup'].controls['vId'];

但它不起作用。请在这里需要一些帮助。

希望这可以帮助...

let vId = this.orderForm.get('vlanFormGroup').get('vId')
