javascript - 如何在javascript中转换json数据

Question

我正在尝试使用数据脚本函数转换数据。但我无法在其父数组中添加子项。

var a ={
            "GENERAL_INFORMATION": {
              "value": null,
              "type": "LABEL",
              "editable": false,
              "dataType": null,
              "required": false,
              "displayName": null,
              "pattern": null
            },
            " NUMBER": {
              "value": "9876834940",
              "type": "FIELD",
              "editable": false,
              "dataType": "",
              "required": false,
              "displayName": null,
              "pattern": null
            },
            "CON TYPE": {
              "value": "retailnn_cyn",
              "type": "FIELD",
              "editable": false,
              "dataType": "",
              "required": false,
              "displayName": null,
              "pattern": null
            },
            "User INFORMATION": {
              "value": null,
              "type": "LABEL",
              "editable": false,
              "dataType": null,
              "required": false,
              "displayName": null,
              "pattern": null
            },
            "Title": {
              "value": "Mr",
              "type": "FIELD",
              "editable": true,
              "dataType": "",
              "required": true,
              "displayName": null,
              "pattern": null
            },
            "Gender": {
              "value": "M",
              "type": "FIELD",
              "editable": true,
              "dataType": "",
              "required": true,
              "displayName": null,
              "pattern": null
            },
            "DOB": {
              "value": "23-Oct-1984",
              "type": "FIELD",
              "editable": true,
              "dataType": "DATE",
              "required": true,
              "displayName": null,
              "pattern": null
            }
    };




    var o = [];

    for (var i in a){
      if(a[i].type==='LABEL'){
        a[i].text = i;
        a[i].children = []
        o.push(a[i])
      }else if(a[i].type==='FIELD'){

      }

    }

获取输出；

[{
    "value": null,
    "type": "LABEL",
    "editable": false,
    "dataType": null,
    "required": false,
    "displayName": null,
    "pattern": null,
    "text": "GENERAL_INFORMATION",
    "children": []
}, {
    "value": null,
    "type": "LABEL",
    "editable": false,
    "dataType": null,
    "required": false,
    "displayName": null,
    "pattern": null,
    "text": "User INFORMATION",
    "children": []
}]

预期输出

[{
    "value": null,
    "type": "LABEL",
    "editable": false,
    "dataType": null,
    "required": false,
    "displayName": null,
    "pattern": null,
    "text": "GENERAL_INFORMATION",
    "children": [
      {
          "value": "9876834940",
          "type": "FIELD",
          "editable": false,
          "dataType": "",
          "required": false,
          "displayName": null,
          "pattern": null,
        "text": "NUMBER",
        },
     {
          "value": "retailnn_cyn",
          "type": "FIELD",
          "editable": false,
          "dataType": "",
          "required": false,
          "displayName": null,
          "pattern": null,
       "text": "CON TYPE",
        }
    ]
}, {
    "value": null,
    "type": "LABEL",
    "editable": false,
    "dataType": null,
    "required": false,
    "displayName": null,
    "pattern": null,
    "text": "User INFORMATION",
    "children": [
      {
          "value": "Mr",
          "type": "FIELD",
          "editable": true,
          "dataType": "",
          "required": true,
          "displayName": null,
          "pattern": null,
        "text": "Title",
        },
      {
          "value": "M",
          "type": "FIELD",
          "editable": true,
          "dataType": "",
          "required": true,
          "displayName": null,
          "pattern": null,
          "text": "Gender",
        },
         {
          "value": "23-Oct-1984",
          "type": "FIELD",
          "editable": true,
          "dataType": "",
          "required": true,
          "displayName": null,
          "pattern": null,
          "text": "DOB",
        }
    ]
}]



console.log(JSON.stringify(o))

您的代码更新了 a 元素，不确定这是不是一个好主意...

这是“我的解决方案”:(我改了名字 a，o)

const Primo = { 'GENERAL_INFORMATION':
