How to make form model update on blur in angular 2

Question

Is there an equivalent to this in angular 2?

ng-model-options="{ updateOn: 'blur' }"

Thanks

Answer 1

In Angular 2 you can use the native DOM events

<input (blur)="someMethod()" />

Now, just define a method that does what you need when the field is blurred

Answer 2

Even though this is a very old thread, there is now a very neat solution which comes with Angular5.

You trigger the update on blur like this:

Tempalte driven forms:

<input [(ngModel)]="lastname" [ngModelOptions]="{ updateOn: 'blur' }">

Reactive forms:

this.nameForm = new FormGroup ({
  firstname: new FormControl('', {
    validators: Validators.required,
    updateOn: 'submit'
  }),
  lastname: new FormControl('', {
    validators: Validators.required,
    updateOn: 'submit'
  })
});

(you can select submit or blur as values)
