After creating a sample file for validation, everything seems to be working smoothly...
However, I now have a specific requirement - I would like to make some modifications while validating. The error message should automatically display in a tooltip. This tooltip should appear automatically when there is an error and disappear once the error is resolved. It should remain visible until the error is fixed.

If it's possible to achieve this without using jQuery or with the use of jQuery, that works too.

var app = angular.module('myapp', ['UserValidation']);
myappCtrl = function($scope) {
$scope.formAllGood = function () {
return ($scope.usernameGood && $scope.passwordGood && $scope.passwordCGood)

}
angular.module('UserValidation', []).directive('validUsername', function () {
return {
require: 'ngModel',

ctrl.$parsers.unshift(function (viewValue) {
// Any way to read the results of a "required" angular validator here?
