Question

我将在一个页面中选择图像，并在其他页面中显示所选择的5个图像。在向服务器发送put请求之前，所选图像最初将存储在选择阵列中。在显示页面时，我有一个名为更改图片的按钮，我在选择图像页面中选择5个图像后向服务器发送放置请求，将存储在名为 other_media 的数组中。如果我点击更改图片按钮它将重定向到选择图像页面（再次选中的数组将为空）在选择图像页面时，那些已经选择显示在右侧的图像[意味着我需要将other_media数组中的数据推送到选定的数组]在plunker中的结果。我需要准确地显示已经选择（张贴或放置）的图像。只有一页我选择了图像。 Plunker https://plnkr.co/edit/BM4AavLn9uKxKL4wdbT6?p=preview

  <!--I have id in my work. but here we don't have id. i need to save particular object in an selected array to  another array -->

 <button ng-click="setMediaForCurrentPin(selected)" class="btn btn-success" style="margin:50px auto; display:table;">Submit</button>

的的Javascript

     $scope.selected = [];

        FromOne2Another = function(source, target, item) {
            target.push(item);
            source.splice(source.indexOf(item), 1);

        }
//this is the starting of code where i send the selected pitures from unselected before put request.
        $scope.toselected = function(item) {
            FromOne2Another($scope.pinMedia, $scope.selected, item);
        }

        $scope.tosource = function(item) {
            FromOne2Another($scope.selected, $scope.pinMedia, item);

        }
//this is the ending of above code
//From here i am trying to get the data from the stored media
          $scope.toSelectedArray=function(item){

            FromOne2Another($scope.other_media, $scope.selected, item);
            console.log($scope.pins);
         }

如果我在服务中使用这样的话，为什么我会得到Cannot read property 'splice' of undefined 一个我的网站视频，以了解https://nimbus.everhelper.me/client/notes/share/376595/vyEMbEoxsFIfN3X39T5tLdbD8aGfxAgF
