我有一个动态 formArray，保存数据，一切工作正常，但我在修补值时遇到问题，而且我在网上找不到任何确切的解决方案。

下面是代码，

        <div formArrayName="educationForm">
            <div *ngFor="let education of educationAndExperienceForm.controls.educationForm['controls'];let i = index;"

                    [ngClass]="{ 'input-error': submitted && educationAndExperienceForm.controls.educationForm.controls[i].invalid }">
