</form>
<script id="jsbin-javascript">
angular.module('myApp', [])
.controller('FormController', function($scope) {
$scope.fields = [
{placeholder: 'Username', isRequired: true},
{placeholder: 'Password', isRequired: true},
{placeholder: 'Email (optional)', isRequired: false}

The following CSS classes are set automatically, depending on the validity of the form:
ng-valid when form is valid
ng-invalid when form is invalid
ng-pristine when form is pristine
ng-dirty when form is dirty
To specify which method to call when submitting form, use one of the
following two directives:
ng-submit on the form element
ng-click on the first button or input field of type submit (input[type=submit])
