使用弹出窗口在 ANGULAR 中添加项目 json

Question

我正在做一个网络应用程序。

我有一个动态表格。首先，您选择 PRODUCT，然后选择 LOT。选择中的项目列表由 json 获取。现在的问题是我想添加创建新项目以添加到<select> LOT 的可能性。

所以，首先我尝试使用以下代码在 LOT 列中添加该字段：

  $scope.addLot = function(id,val,lotId) { 
    // console.log(id);
    var inWhichProduct = id;
    var newArray = { "value": val, "id": lotId };
   //console.log($scope.items)
    angular.forEach($scope.items,function(v,i){
      if($scope.items[i].id == id )
      {
        $scope.items[i].lots.push(newArray);
        console.log($scope.items[i].lots);
      }
    });
  };

它可以工作（here 就是一个例子）。但我想要做的是在模式窗口中移动这些字段。我试过这个，但它不起作用（here 是另一个例子）。为什么？也许正确的方法是在json中添加item，然后刷新LOT，但是如何在json中添加item呢？

angular.module('app', []).controller('ExampleController', ['$scope',
        function($scope) {
          $scope.infos = [
            {name: "i will go to modal 1"},
            {name: "i will go to modal 2"}
          ];

          $scope.goToModal = function(info) {
            $scope.newDataInModal = info;
          }
        }
      ]);
