issue with adding string to listbox using angularjs

When attempting to add the string "New" to a list box, it is being inserted as "undefined".

  $http({
            method: 'GET',
            url: 'http://xxx/api/Maintenance/GetAllFilteredItems',
            params: { Pt_Id: PtId}
        }).then(function successCallback(response) {
            $scope.items = response.data;         
        }, function errorCallback(response) {
            // alert(response);
        });



 $scope.AddNew = function () {
     var Item = [];
        Item[0] = 'New'; alert(Item.length); 
      //  $scope.items.splice(0, 0, Item[0].toString());
        $scope.items.splice(0, 0, Item[0]);
        //  $scope.items.push($scope.input);
        //  $scope.items.splice(0, 0, { itm: 'New'});
        $scope.itm = $scope.items[0];     


        //var item = new String('New')
        //$scope.items.splice(0, 0, item);
        //$scope.items.unshift(item);
}

Have tried multiple approaches without success.

Answer №1

Make sure that the items within the $scope.items are actually objects and not just strings, as attempting to insert a string into a listbox expecting objects will result in it being inserted as undefined.

To successfully push any string you desire into the listbox, try pushing the items like this:

public List yourmethod() {....} // to $scope.items
