在Angular 2中提交vs ngSubmit

Question

In order to submit a form in Angular 2 we can either use form's "submit" or "ngSubmit" event.

<form #frm="ngForm" (submit)="add(frm.value)">
  ...
</form>

<form #frm="ngForm" (ngSubmit)="add(frm.value)">
  ...
</form>

Would like to know whats the difference between the two ?
