如何将对象插入到json对象/数组中

Question

我有一个json对象，它包含多个父项（由parent属性表示为null），它有嵌套的子对象。

{
  "aggregateId": null,
  "aggregateList": {
    "name": "My Grocery Store",
    "children": [
      {
        "name": "Vegetables",
        "documentType": "Produce",
        "parent": null,
        "count": 2,
        "children": [{
            "name": "Carrots",
            "documentType": "Produce",
            "parent": null,
            "count": 1447,
            "children": null
            },
            {
            "name": "Lettuce",
            "documentType": "Produce",
            "parent": null,
            "count": 311,
            "children": null
            }]
      },
      {
        "name": "Canned Goods",
        "documentType": "Cans",
        "parent": null,
        "count": 583,
        "children": null
      }
    ]
  }
}

我要做的是当返回一个子对象的新对象时将其插入到现有数组中。例如，返回对象Celery

{
    "name": "Celery",
    "documentType": "Produce",
    "parent": null,
    "count": 100,
    "children": null
}

遍历树，找到它的父（产生）并将其插入到该数组中。

{
      "aggregateId": null,
      "aggregateList": {
        "name": "My Grocery Store",
        "children": [
          {
            "name": "Vegetables",
            "documentType": "Produce",
            "parent": null,
            "count": 2,
            "children": [{
                "name": "Carrots",
                "documentType": "Produce",
                "parent": null,
                "count": 1447,
                "children": null
                },
                {
                "name": "Lettuce",
                "documentType": "Produce",
                "parent": null,
                "count": 311,
                "children": null
                },
                {
                 "name": "Celery",
                 "documentType": "Produce",
                 "parent": null,
                 "count": 100,
                 "children": null
                 }]
          },
          {
            "name": "Canned Goods",
            "documentType": "Cans",
            "parent": null,
            "count": 583,
            "children": null
          }
        ]
      }
    }

到目前为止，我已尝试使用for语句迭代集合，但这似乎不对，我没有得到返回的结果。看似不打架的部分是指定树中的位置。

有没有办法通过javascript获取对象/数组并查看每个属性以找到匹配的值，然后将新对象插入该数组？

更新

抱歉，我没有提供足够的代码。 for循环包含在函数

中

    function nestAssociation(node, oldCollection, newAggregates)
       {
           var parent = node.documentType; //the parent value of the collection to be inserted
           var currentCollection = oldCollection; //previous collection
           var newCollection = newAggregates; //the object to be inserted (Celery)

for (var i = 0, iLen = arrayCount; i < iLen; i++) {
               if ($scope.myList.children[0].children[i].documentType == node.documentType) {
                   console.log('true');
                  var myNewList = $scope.myList.children.concat(newCollection.children)
                  $scope.myList = myNewList;
                   console.log(myNewList)
            }
}
