Angular 2 (Angular 4) - Form Validation
Angular 2 (Angular 4) - Form Validation
In this video we take a look at angular 2 validation for the first time. We look at how Angular 2 bootstraps specific css classes to each control that based on user interaction changes. These classes are ng-untouched, ng-touched, ng-dirty, ng-pristine, ng-valid, ng-invalid.
We also look into how we can access the form control properties within the markup to determine the state of a control in real time and toggling Bootstrap css classes based on the state of the control as well. All validation in this video is based on the required attribute in HTML5.
