如何转换json文件？

Question

我有json个文件，但我不知道如何转换。

我正在尝试使用stringily或parse，但是它不起作用。

在下面查看我的json数据：

  first: {
     'big': {
       'letter': 'let',
       'Can go walk': 'CGW',
       'something': 'smthg'
     },
     'low': {
       'call_me': 'call me',
       'just_do_it': 'just do it'
     }
}

我需要将其转换为以下格式：

  first: [{
     big: [
       {name: 'letter', value: 'let'},
       {name: 'Can go walk', value: 'CGW'},
       {name: 'something', value: 'smthg'}
     ],
     low: [
       {name: 'call_me', value: 'call me'},
       {name: 'just_do_it', value: 'just do it'},
     ]
}]

如何将格式1转换为格式2（在此情况下，我将对象转换为格式2并在格式转换为1后进行一些更改

Answer 1

JSON标准是使用双引号，JS的JSON.parse()函数现在可以使用单引号。尝试以下方法：

var x = JSON.parse('{"big": {}, "low": {}}')

var arr = [x["big"], x["low"]]

Answer 2

一种替代解决方案（杂乱无章）

const json = {
 first: {
   'big': {
    'letter': 'let',
    'Can go walk': 'CGW',
    'something': 'smthg'
   },
   'low': {
    'call_me': 'call me',
    'just_do_it': 'just do it'
   }
 }
}
let arr = [{}]
for (let prop_lv0 in json) {
 arr[0][prop_lv0] = [{}];
  for (let prop_lv1 in json[prop_lv0]) {
   arr[0][prop_lv0][0][prop_lv1] = [];
    for (let prop_lv2 in json[prop_lv0][prop_lv1]) {
     arr[0][prop_lv0][0][prop_lv1].push({ name: prop_lv2, value: json[prop_lv0][prop_lv1][prop_lv2] })
    }
   }
 }
console.log(arr)
