Angular 生成窗体时控件和抽象控件出错

我有以下表格：

this.myForm = new FormGroup({
        points: new FormArray([
            new FormGroup({
                date: this.date,
                startTime: new FormControl(null, Validators.required),
                endTime: new FormControl(null, Validators.required),
            }),
            new FormGroup({
                date: this.date,
                startTime: new FormControl(),
                endTime: new FormControl(),
            }),
            new FormGroup({
                date: this.date,
                startTime: new FormControl(),
                endTime: new FormControl(),
            })
        ]),
    });

for (const group of (this.myForm.get('points') as FormArray).controls) {
            console.log(group);
            if (group.controls.date !== null) {
                if (group.controls.date.value !== null) {
                    group.controls.startTime.setValue(
                        group.controls.date.value + ' ' + group.controls.startTime.value
                    );
                    group.controls.endTime.setValue(
                        group.controls.date.value + ' ' + group.controls.endTime.value
                    );
                    group.controls.date.setValue(group.controls.date.value);
                }
            }
        }

当我提交时，我有以下表格：

this.myForm = new FormGroup({
        points: new FormArray([
            new FormGroup({
                date: this.date,
                startTime: new FormControl(null, Validators.required),
                endTime: new FormControl(null, Validators.required),
            }),
            new FormGroup({
                date: this.date,
                startTime: new FormControl(),
                endTime: new FormControl(),
            }),
            new FormGroup({
                date: this.date,
                startTime: new FormControl(),
                endTime: new FormControl(),
            })
        ]),
    });

for (const group of (this.myForm.get('points') as FormArray).controls) {
            console.log(group);
            if (group.controls.date !== null) {
                if (group.controls.date.value !== null) {
                    group.controls.startTime.setValue(
                        group.controls.date.value + ' ' + group.controls.startTime.value
                    );
                    group.controls.endTime.setValue(
                        group.controls.date.value + ' ' + group.controls.endTime.value
                    );
                    group.controls.date.setValue(group.controls.date.value);
                }
            }
        }

工作正常，但当我尝试

ng build--prod

时，出现错误：

类型“AbstractControl”上不存在属性“controls”

。如何访问FormArray中FormGroup的控件

---

提前感谢。

问题是您必须将组专门转换为FormGroup：

for (const group of (this.myForm.get("points") as FormArray).controls as FormGroup[]) {

---

也许这可以通过专门将组强制转换为FormGroup来解决吗？@GeckoIT我试过了，但没有结果（const group of（this.myForm.get（“points”）作为FormArray）。控件作为FormGroup[]）{…似乎在我这边起了作用。是的！谢谢
