I'm getting info from a json file, and i need to store some items on local storage.

This is my code to get the data from json file:

    $scope.selection = "Selecciona una categoría";



    $scope.filterAvailable = function(available){

        var filteringBy = ;



        $http.get('/app/json/file.json')

        .then(function(data){

            $scope.listOfProducts = data.data.products;



                for(var i = 0; i< $scope.listOfProducts.length; i++){

                    if($scope.listOfProducts[i].available === true && $scope.listOfProducts[i].sublevel_id === $scope.inside){

                        filteringBy.push($scope.listOfProducts[i]);

                    }

                }



                $scope.dataOnFilter = filteringBy;

        });

    }

And with a ng-repeat, i show the info on my html view:

<ul>

   <li ng-repeat="data in dataOnFilter"><a ng-click="selected(data)">{{data.name}}</a>

</ul>

Then, i catch the specific value and save on local storage by clicking on the <a> tag with the next piece of code:

    $scope.selected = function(y){

        $scope.dataAdd = y;



        localStorage.setItem('valid', JSON.stringify($scope.dataAdd));

    }

If i want to see the selected info on a modal, just have to click on another button:

    $scope.openCart = function(){

        $scope.myItems = JSON.parse(localStorage.getItem('valid'));



        $('#cart').modal({

            show: true

        });

    }

Everything is perfect if i select one item, but, if i choose another, the info are rewrited. What i need is store all the selected items in the local storage.

Someone can help me, please?

I'm using AngularJs and Javascript.

You should store your data as an Array instead of Object. This function add selected value to an array named collection.

$scope.selected = function(y) {

    $scope.dataAdd = y;



    localStorage.collection = localStorage.collection || "";

    var collection = JSON.parse(localStorage.collection);

    collection.push($scope.dataAdd);

    localStorage.collection = JSON.stringify(collection);

}
