在现有的json对象中添加新的键（数组）

Question

I've got an array with objects. I need for each object to add a key, which will be an array of other objects.

So my code looks like this:

$scope.array = [];

$http.get(url).success(function(data) {

   $scope.array = data;

   // Now my array has some objects
   var i = 0;
   function() getSomeData(i) { 
      if(i<array[i].length()) {
         $http.get(url + array[i].someKey).success(function(data){
            $scope.array[i].push(data);
            i++;
            getSomeData(i);
         })
      } 
   }

})

getSomeData(0);

But I am getting Error:array.push is not a function

Why's that happening ?

Answer 1

You are trying to push to an object instead of the array. Either do:

$scope.array.push(data) to add a new object.

or do $scope.array[i] = data to update the object at the specific index in the array.

Answer 2

Objects in JSON are added using below two techniques. You can try one of them.

object["property"] = value;

or

object.property = value;
