User Input Form Validation with AngularJS

Hi, friends in this post we going to learn user input form validation with AngularJS. Now we’ll be looking at the ways that AngularJS supports us do form validations. We’ll focus on client side validation and use the built in AngularJS form properties. The ng-valid and ng-invalid will automatically decide if an input is good based on the controls placed on the form. Now work through adding an error message for all of our inputs fields if they are not $valid and have previously been used. So we don’t need to show an error since they’ve been used. AngularJS will automatically decide if we should show an error based on an inputs $invalid and $pristine properties.
