Check if FormGroup has been submitted [duplicate]

Question

In template-driven form, we can check that with the submitted property from NgForm. But how to achieve that in Model-driven form?

Answer 1

I just found out you can use ngForm together with formGroup:

<form [formGroup]='form' #ngForm="ngForm" (ngSubmit)='validation(ngForm)' 
  [ngClass]="{ 'form-unsubmitted': !ngForm.submitted}">

Answer 2

Create one variable IsSubmitted = false into component. Once submit a button you can set it true into onSubmit() function. for example :

onSubmit(): void{
     this.isSubmited = true;
  // code....
}

set it again to false after response
