Execute function when button is not active

Within my Angular 2 application, I have a form along with the following code snippet that relates to the button responsible for submitting the form.

<button (mouseover)="showMesageValidation()" class="edm-button" type="submit" [disabled]="!f.valid">confirm</button>

I am looking to execute a method that displays fields that have not been properly validated. However, I came across information suggesting that disabled elements do not trigger events. So, my question is, how can I display a list of invalid items when hovering over the button?

Answer №1

To display errors only when they exist, utilize an *ngIf directive with a similar condition:

<div *ngIf="!f.valid">
 <div *ngFor="let err of errors">{{err}}</div>
</div>
