Javascript Question

ng-model input inside an angular-ui modal controller is undefined

In my modal template I'm trying to use

ng-model
to assign a value to the scope of my controller (
$scope.name
), but it doesn't work. It gives me
undefined
. What am I doing wrong? Plunker here

I expect that the modal creates its own scope, and puts
name
into that scope because I used
ng-model
. It seems to be active inside the modal controller as I can output it fine using
{{name}}


<div ng-controller="ModalDemoCtrl">
<script type="text/ng-template" id="myModalContent.html">
<div class="modal-body">
Name: <input type="text" ng-model="name">
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
</div>
</script>
<button class="btn" ng-click="open()">Open me!</button>
</div>


Javascript:

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal, $log) {
$scope.open = function () {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: ModalInstanceCtrl
});
};
};

var ModalInstanceCtrl = function ($scope, $modalInstance) {
$scope.ok = function () {
$modalInstance.close($scope.name);
alert('name was: ' + $scope.name)
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};

Answer

The model name is created inside a different scope. Use an object:

var ModalInstanceCtrl = function ($scope, $modalInstance) {
    $scope.data = {
        name:""
    };
    $scope.ok = function () {
        alert('name was: ' + $scope.data.name);
        $modalInstance.close($scope.data.name);
    };
