[angularjs] AngularJS - Passing data between pages

I am an AngularJS starter. I am trying to send data from :

• Page A : Van Listing page

  to

• Page B: Van Update page.

When user click the update link for a van, I am invoking a controller and retrieving the van details in the controller. But, I cannot assign the van details to the Page B ( Van Update Page) using the same controller... Error "Cannot set property 'vanNumber' of undefined"

*** Page A: Van List ****

<form name="listVanForm" >
   <table>
   <tr> <td ng-controller="VanUpdateCtrl"><a href="#/van-update" ng-click="prePopulateForm(row.members.vanNumber.value )" class="btn btn-small btn-primary">update</a></td> </tr>
   </table>
</form>

*** Page B: Van Update ****

  <div class="container">
        <h2>Edit Van </h2>
    
        <form name="updateVanForm" novalidate="novalidate" class="form-horizontal" ng-submit="updateCard(formData)">
            <div class="control-group">
                <label class="control-label" >Van Number:</label>
    
                <div class="controls">
                    <input type="text" id="vanNumber" ng-model="formData.vanNumber" placeholder=""/>
                </div>
            </div>
        </form>
     </div>

*** VanUpdateCtrl **

   app.controller('VanUpdateCtrl', ['$scope', 'VanUpdateFactory', '$location',
                                      function ($scope, VanUpdateFactory, $location) {
    
        //callback for ng-init 'populateDD':    
        $scope.prePopulateForm = function (cardNoParam m) {
            
            alert('cardNo = '+cardNoParam);
            
            $scope.formData.cardNumber=cardNoParam;}
    }
    
So, $scope.formData.cardNumber OR $scope.formData in the destination page is not recognised.

app.factory('persistObject', function () {

        var persistObject = [];

        function set(objectName, data) {
            persistObject[objectName] = data;
        }
        function get(objectName) {
            return persistObject[objectName];
        }

        return {
            set: set,
            get: get
        }
    });

Fill it with data like this

persistObject.set('objectName', data); 

Get the object data like this

persistObject.get('objectName'); 

If you only need to share data between views/scopes/controllers, the easiest way is to store it in $rootScope. However, if you need a shared function, it is better to define a service to do that.

What you should do is create a service to share data between controllers.
