How to trigger Angular 2 input validation manually?

Question

I have two inputs:

• First one on which I apply my custom validator
• Second one which value I use in my custom validator (it is dynamic and editable)

If I apply my custom validator on the first input, then I focus the second one and change the value - I want to force first inputs re-validation...

At the moment it only re-validates first input when I change the value... Any suggestions?

At the moment when I focus the first input I can access it's reference:

<input     name="mEnd"     class="form-control"     [(ngModel)]="endDate"        ...     #endDateInput="ngModel"     (focus)="clog(endDateInput)" > 

I wonder can I trigger re-validation using the input formControl reference methods?

Answer 1

You can update the validity of a formControl

form.controls['myControl'].updateValueAndValidity();
