Angular 2 - Form is invalid when browser autofill

Question

I have a Login Form which has email and password fields.

I've chosen for browser autofill.

The problems is: When browser autofills login form, both fields are pristine and untouched, so the submit button is disabled.

If I click on disabled button, it enables and fires submit action, what is nice. But the default disabled aspect is pretty bad what can make some users disappointed.

Do you have some ideas about how to deal with?

Answer 1

I solved this problem with the ChangeDetectorRef Provider.
Simply do a manual detectChanges() before you check if the input is valid.

If you aren't able to check after a button click, then hear on the Input-Event of the Input-Element with the event-binding (input)=changedetectorfunc() and call the changeDetector in this function.
Therefore it must work.
Hope, it helps you.
