I am creating an AngularJS form and after filling in the form to get the data in JSON format. To get JSON data from this form works but I can't get JSON of the complete form.

I tried to create a user object in the $scope variable by changing

$scope.reset = function () {
    $scope.voornaam = "Mark";
    $scope.achternaam = "Schuurman";
    $scope.afdeling = "ICT";
    $scope.geboortedatum = new Date("Jan, 01, 0000");
    $scope.telefoon = +31412123456;
    $scope.inschrijvingsdatum = new Date("Jan, 01, 0000");
    $scope.mobiel = +31612345678;
    $scope.email = "[email protected]";
}

in

$scope.reset = function () {
    $scope.user.voornaam = "Mark";
    $scope.user.achternaam = "Schuurman";
    $scope.user.afdeling = "ICT";
    $scope.user.geboortedatum = new Date("Jan, 01, 0000");
    $scope.user.telefoon = +31412123456;
    $scope.user.inschrijvingsdatum = new Date("Jan, 01, 0000");
    $scope.user.mobiel = +31612345678;
    $scope.user.email = "[email protected]";
}

and

<input type="button" ng-click="showJson()" value="Object To JSON" /><hr />
    {{voornaam | json}}
</div>

in

<input type="button" ng-click="showJson()" value="Object To JSON" /> <hr />
    {{user| json}}
</div>

For every input field, I changed the ng-model

<tr>
    <td>Email: </td>
    <td>
       <input name="email" type="email" ng-model="email" length="100" required>
       <span style="color:red" ng-show="formulier.email.$dirty && formulier.email.$invalid">
          <span ng-show="formulier.email.$error.required">Email is verplicht.</span>
          <span ng-show="formulier.email.$error.email">Ongeldig e-mailadres.</span>
       </span>
    </td>
</tr>

to

<tr>
   <td>Email: </td>
    <td>
        <input name="email" type="email" ng-model="user.email" length="100" required>
        <span style="color:red" ng-show="formulier.email.$dirty && formulier.email.$invalid">
            <span ng-show="formulier.email.$error.required">Email is verplicht.</span>
            <span ng-show="formulier.email.$error.email">Ongeldig e-mailadres.</span>
        </span>
     </td>
</tr>

But I receive the following error:

0x800a138f - JavaScript runtime error: Unable to get property voornaam of undefined or null reference.

How can I display the total content of the form in JSON format?

I think you have to initialized user like $scope.user={};

Please refer this jsfiddle link with all your fixed code : You have to initialize $scope.user={} in your controller.

Fixed code:

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

        mainApp.controller('formulierController', function ($scope) {
            var vm = this;
            vm.reset = function () {

                vm.voornaam = "Mark";
                vm.achternaam = "Schuurman";
                vm.afdeling = "ICT";
                vm.geboortedatum = new Date("Jan, 01, 0000");
                vm.telefoon = +31412123456;
                vm.inschrijvingsdatum = new Date("Jan, 01, 0000");
                vm.mobiel = +31612345678;
                vm.email = "[email protected]";
            }
            vm.reset();

            vm.showJson = function () {
                vm.json = angular.toJson([
                  vm.voornaam,
                  vm.achternaam,
                  vm.afdeling,
                  vm.geboortedatum,
                  vm.telefoon,
                  vm.inschrijvingsdatum,
                  vm.mobiel,
                  vm.email
                ]);
            }

Always use "Controller as" - this is recommended
