forms - How to make 'submit' button disabled?

Question

How to disable the "Submit" button until the form is valid?

Does angular2 have an equivalent to ng-disabled that can be used on the Submit button? (ng-disabled doesn't work for me.)

Answer 1

As seen in this Angular example, there is a way to disable a button until the whole form is valid:

<button type="submit" [disabled]="!ngForm.valid">Submit</button>
