[SOLVED] Angular2 - Validate and submit form from outside

Angular2 - Validate and submit form from outside

I have a simple form that looks like this

<form (ngSubmit)="save()" #documentEditForm="ngForm">
...
</form>

and need to submit the the form and check its validity from outside

eg. Either submit it programatically, or with a <button type="submit"> that is outside the <form> tags.

Solution

Found out how to do it:

trigger submit with <formname>.ngSubmit.emit()
get form status with <formname>.form.valid

Example:

<form (ngSubmit)="save()" #documentEditForm="ngForm">
...
</form>

<button class="btn-save button primary"
(click)="documentEditForm.ngSubmit.emit()"
[disabled]="!documentEditForm.form.valid">SAVE</button>

Edit: As @yuriy-yakovenko has pointed out, you should add in your component code the following:

@ViewChild('documentEditForm') documentEditForm: FormGroupDirective;

And don't forget to import the FormGroupDirective if you haven't done yet
