Check if FormGroup has been submitted

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

我发现您可以将ngForm与formGroup一起使用：

<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 false into after response
