分层数据，如何循环所有级别并将附加数据插入每个节点

Question

我在 Javascript 中有分层数据，如下所示，我试图找到在每个 comments 节点中添加 jsonStringify 的方法，该怎么做？

var o = {
  "comments": {
    "count": 2,
    "data": [
      {
        "text": "..",

        "comments": {
          "count": 1,
          "data": [
            {
              "text": "..",

              "comments": {
                "count": 0,
                "data": [],
                // "jsonStringify":
              }
            },
          ],
          // "jsonStringify":
        }
      },

      {
        "text": "..",

        "comments": {
          "count": 0,
          "data": [],
          // "jsonStringify":
        }
      },     
    ],
    // "jsonStringify":
  }
};

添加jsonStringfy
这只适用于知道有多少级别

var jsonStringify = JSON.stringify(o.comments);
o.comments.jsonStringify = jsonStringify;

for (var i = 0; i < o.comments.data.length; i++) {
  var jsonStringify = JSON.stringify(o.comments.data[i].comments);
  o.comments.data[i].comments.jsonStringify = jsonStringify;
}

例如上面的数据有2个分支，最深的层次是3（
"comments" > "comments" > "comments",
"comments" >"comments"),
我想找到每个 "comments" 得到如下值 1 并应用于 JSON.stringify 函数得到结果然后修改相同的节点插入结果成为 2

1
"comments": {
  "count": 0,
  "data": []
}
2
"comments": {
  "count": 0,
  "data": [],
  "jsonStringify": "{\"count\":0,\"data\":[]}"
}

数据不明多少级我自己找方法

在修改原始问题之前回答了不同计数的备注。还等作者详细说呢

源代码：

var o = {
  "comments": {
    "count": 2,
    "data": [
      {
        "text": "..",
        "comments": {
          "count": 1,
          "data": [
            {
              "text": "..",

              "comments": {
                "count": 0,
                "data": [],
              }
            },
          ]
        }
      },
      {
        "text": "..",
        "comments": {
          "count": 0,
          "data": []
        }
      }
    ]
  }
};

function jsonStringify(array){
  for(var i=0;i<array.length;i++){
    var ar = array[i];
    ar.comments.jsonStringify = JSON.stringify(ar.comments);
    ar.comments.data = jsonStringify(ar.comments.data);
    array[i] = ar;
  }
  return array;
}

var result = jsonStringify([o]);

console.log( JSON.stringify(result,null,'\t') );

结果：

[
    {
        "comments": {
            "count": 2,
            "data": [
                {
                    "text": "..",
                    "comments": {
                        "count": 1,
                        "data": [
                            {
                                "text": "..",
                                "comments": {
                                    "count": 0,
                                    "data": [],
                                    "jsonStringify": "{\"count\":0,\"data\":[]}"
                                }
                            }
                        ],
                        "jsonStringify": "{\"count\":1,\"data\":[{\"text\":\"..\",\"comments\":{\"count\":0,\"data\":[]}}]}"
                    }
                },
                {
                    "text": "..",
                    "comments": {
                        "count": 0,
                        "data": [],
                        "jsonStringify": "{\"count\":0,\"data\":[]}"
                    }
                }
            ],
            "jsonStringify": "{\"count\":2,\"data\":[{\"text\":\"..\",\"comments\":{\"count\":1,\"data\":[{\"text\":\"..\",\"comments\":{\"count\":0,\"data\":[]}}]}},{\"text\":\"..\",\"comments\":{\"count\":0,\"data\":[]}}]}"
        }
    }
]
