在嵌套的JSON结构中更改密钥名称 [英] Change key name in nested JSON structure

问题描述

我有一个JSON数据结构，如下所示：

I have a JSON data structure as shown below:

{
    "name": "World",
    "children": [
      { "name": "US",
          "children": [
           { "name": "CA" },
           { "name": "NJ" }
         ]
      },
      { "name": "INDIA",
          "children": [
          { "name": "OR" },
          { "name": "TN" },
          { "name": "AP" }
         ]
      }
 ]
};

我需要更改名称中的键名称& 孩子们说关键& 值。关于如何为这个嵌套结构中的每个键名做这个的建议？

I need to change the key names from "name" & "children" to say "key" & "value". Any suggestion on how to do that for each key name in this nested structure?

推荐答案

我不知道为什么你有一个您的JSON标记结尾处的分号（假设您在问题中表示的内容），但如果删除了分号，则可以使用 reviver函数进行修改解析数据时。

I don't know why you have a semicolon at the end of your JSON markup (assuming that's what you've represented in the question), but if that's removed, then you can use a reviver function to make modifications while parsing the data.

var parsed = JSON.parse(myJSONData, function(k, v) {
    if (k === "name") 
        this.key = v;
    else if (k === "children")
        this.value = v;
    else
        return v;
});
