“EXCEPTION：Uncaught(承诺)：TypeError：value.forEach不是函数
TypeError：value.forEach不是FormArray.setValue中的函数“

组件类：

jobDetails: FormGroup;
techFormArray: FormArray;

constructor(private formBuilder: FormBuilder){

    this.techFormArray = new FormArray([
        new FormControl(''),new FormControl(''),new FormControl('')
    ]);
    this.jobDetails = this.formBuilder.group({
        techs: this.formBuilder.array([])
    });
    this.jobDetails.setValue({
        techs: this.techFormArray
    });
}

HTML：

<form [formGroup]="jobDetails">
  <div formArrayName="techs" >
    <div style="display: flex; flex-direction: column">
      <div *ngFor="let tech of techFormArray.controls; let i=index">
        <md-checkBox [formControlName]="i">
          {{i}}
        </md-checkBox>
      </div>
    </div>
  </div>
</form>

解：

FunStuff没错,我无法使用setValue ….所以我删除了它.问题解决了哈哈.我改变了一些事情,我不确定我做了什么,它基本上是蛮力的试验和错误几个小时,但后来它工作了！
