Validation du mot de passe et confirmation des champs du mot de passe à chaque fois que l'un des champs est modifié

J'ai actuellement une directive angulaire qui valide un mot de passe et confirme le champ de mot de passe comme correspondant. Cela fonctionne à un point, il jette une erreur lorsque les mots de passe ne correspondent pas. Cependant, l'erreur ne sera rejetée que lorsque vous aurez entré des données dans les deux champs. Comment puis-je faire en sorte que l'erreur pour les mots de passe incompatibles soit renvoyée dès que vous entrez des données dans un champ ou dans un autre?

Voici la directive (il faut l'ajouter aux deux champs qui doivent correspondre):

.directive('passwordVerify', function() {
   return {
      restrict: 'A', // only activate on element attribute
      require: '?ngModel', // get a hold of NgModelController
      link: function(scope, elem, attrs, ngModel) {
         //if (!ngModel) return; // do nothing if no ng-model

         // watch own value and re-validate on change
         scope.$watch(attrs.ngModel, function() {
            validate();
         });

         // observe the other value and re-validate on change
         attrs.$observe('passwordVerify', function(val) {
            validate();
         });

         var validate = function() {
            // values
            var val1 = ngModel.$viewValue;
            var val2 = attrs.passwordVerify;

           // set validity
           ngModel.$setValidity('passwordVerify', !val1 || !val2 || val1 === val2);
        };
      }
   };
});

Et voici la directive dans ma forme:

<div class="small-5 columns">
    <div class="small-12 columns">
        <label>
            Password
            <input 
                ng-class="{ notvalid: submitted && add_user_form.user_password.$invalid }" 
                class="instructor-input" 
                id="user_password" 
                type="password" 
                name='user_password' 
                placeholder="password" 
                value='' 
                required 
                ng-model="user.user_password" 
                password-verify="[[user.confirm_password]]"
            >
        </label>
        <p class="help-text">
            <span class="   ">Required</span>
        </p>
        <div 
            class="help-block" 
            ng-messages="add_user_form.user_password.$error" 
            ng-show="add_user_form.user_password.$touched || add_user_form.user_password.$dirty"
        >
        <span class="red">
            <div ng-messages-include="/app/views/messages.html" ></div>
        </span>
    </div>
</div>
<div class="small-12 columns">
    <label>
        Confirm Password
        <input 
            ng-class="{ notvalid: submitted && add_user_form.confirm_password.$invalid }" 
            class="instructor-input" 
            id="confirm_password" 
            ng-model="user.confirm_password" 
            name="confirm_password" 
            type="password" 
            placeholder="confirm password" 
            name="user_confirm_passsword" 
            required 
            password-verify="[[user.user_password]]"
        >
    </label>
    <p class="help-text">
        <span class="   ">
            Enter matching password
        </span>
    </p>
    <div 
        class="help-block" 
        ng-messages="add_user_form.confirm_password.$error" 
        ng-show="add_user_form.confirm_password.$dirty || add_user_form.confirm_password.$touched "
    >
        <span class="red">
            <div 
                ng-messages-include="/app/views/messages.html"
            ></div>
        </span>
    </div>
</div>

Il suffit de changer le dernier chèque:

ngModel.$setValidity('passwordVerify', !val1 || !val2 || val1 === val2);

à:

ngModel.$setValidity('passwordVerify', val1 === val2);

Voici une version working:

(function() {
  "use strict";
  angular
    .module('app', ['ngMessages'])
    .controller('mainCtrl', mainCtrl)
    .directive('passwordVerify', passwordVerify);

  function mainCtrl($scope) {
    // Some code
  }

  function passwordVerify() {
    return {
      restrict: 'A', // only activate on element attribute
      require: '?ngModel', // get a hold of NgModelController
      link: function(scope, elem, attrs, ngModel) {
        if (!ngModel) return; // do nothing if no ng-model

        // watch own value and re-validate on change
        scope.$watch(attrs.ngModel, function() {
          validate();
        });

        // observe the other value and re-validate on change
        attrs.$observe('passwordVerify', function(val) {
          validate();
        });

        var validate = function() {
          // values
          var val1 = ngModel.$viewValue;
          var val2 = attrs.passwordVerify;

          // set validity
          ngModel.$setValidity('passwordVerify', val1 === val2);
        };
      }
    }
  }
})();

J'espère que ça aide.

Voici une solution de travail simple. Nous pouvons simplement utiliser $validators introduit dans Angular 1.3.0 pour obtenir le même résultat:

var app = angular.module("sa", []);

app.controller("FooController", function($scope) {

});

app.directive('passwordVerify', function() {
  return {
    restrict: 'A',
    require: '?ngModel',
    link: function(scope, elem, attrs, ngModel) {
      ngModel.$validators.myPwdInvalid = function(modelValue, viewValue) {
        return viewValue === scope.$eval(attrs.passwordVerify);
      };
    }
  };
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.min.js"></script>

<form name="add_user_form" ng-app="sa" ng-controller="FooController">
    <div class="small-12 columns">
        <label>Password
            <input ng-class="{ notvalid: add_user_form.user_password.$invalid }"
                   type="password" name='user_password' placeholder="password" required
                   ng-model="user.user_password" password-verify="user.confirm_password">
        </label>

        <div class="help-block" ng-messages="add_user_form.user_password.$error"
             ng-show="add_user_form.user_password.$error.$dirty || add_user_form.user_password.$touched">
            <div ng-messages="myPwdInvalid">Password do not match</div>
        </div>
    </div>

    <div class="small-12 columns">
        <label>Confirm Password
            <input ng-class="{ notvalid: add_user_form.confirm_password.$invalid }"
                   ng-model="user.confirm_password"
                   name="confirm_password" type="password" placeholder="confirm password" required
                   password-verify="user.user_password">
        </label>

        <div class="help-block" ng-messages="add_user_form.confirm_password.$error"
             ng-show="add_user_form.confirm_password.$error.$dirty || add_user_form.confirm_password.$touched">
            <div ng-messages="myPwdInvalid">Password do not match</div>
        </div>
    </div>
</form>

Voici une solution facile à comprendre:

<input class="form-control" type="password" name="newpass"  ng-model="newpass">
<input class="form-control" type="password" name="confirmpass"  ng-model="confirmpass">
<div  ng-show="confirmpass != newpass"><hr>Password not matched</div>

C'est ce qui a fonctionné pour moi (laid et hackish):

HTML:

<h1>Password Verification</h1>
<form name="pw" ng-controller="pw">
<p>
  <label for="password">New Password
    <input type="password" name="user_password" ng-model="user_password" ng-required="confirm_password && !user-password" password-verify="confirm_pasword">
    <p ng-show="pw.user_password.$error.passwordVerify">Passwords do not match</p>
    <p ng-show="pw.user_password.$error.required">This field is required</p>
  </label>
</p>
 <p>
  <label for="password">Confirm Password
    <input type="password" name="confirm_password" ng-model="confirm_password" ng-required="user_password && !confirm_password" password-verify="user_password"> 
    <p ng-show="pw.confirm_password.$error.passwordVerify">Passwords do not match</p>
    <p ng-show="pw.confirm_password.$error.required">This field is required</p>
  </label>
</p>
</form>

Puis le script:

angular.module('app', [])
.controller('pw', ['$scope', function($scope){
    $scope.user_password = "";
    $scope.confirm_password = "";

}])
.directive('passwordVerify', function() {
    return {
        restrict: 'A',
        require: '?ngModel',
        link: function(scope, elem, attrs, ngModel) {
            scope.$watch(attrs.ngModel, function() {
                if (scope.confirm_password === scope.user_password) {
                    scope.pw.confirm_password.$setValidity('passwordVerify', true);
                    scope.pw.user_password.$setValidity('passwordVerify', true);
                } else if (scope.confirm_password !== scope.user_password) {
                    scope.pw.confirm_password.$setValidity('passwordVerify', false);
                    scope.pw.user_password.$setValidity('passwordVerify', false);
                }
            });
        }
     };
});
