通过 My Form 输入创建 FormGroup Object

Question

I have created a Form called compaign ; My purpse is to register Form's inputs data within a FormGroup Object and send it to my backend ! The first thing I have done it ; is that I created a FormGroup model i used the class CompaignForms , then i had to instanciate this class using a local variable called compaignexample ; After that i have created the main FormGroup object called compaignform and i had to initialize it with compaignexample attributes using get method ! But the problem is in my template becauz i worked with formControl and ngModel at the beginning ! So i was urged to delete the directive [(ngModel)] and i kept only formControlName , However , the console displays that i have to make a parent component ( [formGroup] ) ! I tried it in vain !! Please how can i fix that problem ! I mentionned my stackblitz demo and it doesnt contain the whole project !! there is a path problem there ! but the only problem which figure out currently is the one above !!

Answer 1

remove this code #compaignForm="ngForm" from your form tag and add this [formGroup]="compaignexample" to your form tag.

<form [formGroup]="compaignexample" (ngSubmit)="saveCompaign()"></form>

ngForm is used when creating Template-driven forms.
