推荐答案

要在FormArray中传递FormControll值，您可以使用angular进行类似的操作，

To pass FormControll Value inside FormArray you can do something like this with angular,

form = new FormGroup({
     name: new FormControl('Name'),
     username: new FormArray([
                  new FormControl("value"),
                  {firstName:"Andrew", lastName:"Donald"},
                  {firstName:"Charles", lastName:"Jackson"}
                ])
   });

希望这对您有帮助.
