javascript - 如何将这个带有字符串的复杂 json 转换为普通的 json 对象，如输出

问题描述

嗨，我的输入 json 是这样的，我想使用 lodash _.map 函数将其转换为预期的输出 [

    {

    },{

        "img":"imageurl",
    "qualityJsonString": "{\"MorphoScore\":\"204\"}
    }]

上面的 json 有一个名为“qualityJsonString”的字段，这个对象是一个字符串 json，所以我面临着将这个字符串转换为正确的 json 格式的问题

我需要像下面这样的格式

{"img":"image url",
  "QualityAttributes": {
    "ISO":{
     "Tinted Glasses":true,
      ......
     },
     "ISOBestPractice":{
        "Mouth Closed Best Practice":true,
         ......
     },
     "ICAO":{
        "No Dark Lenses and no heavy frames and no glares":true,
         ......
     },
     "DepartmentStandard":{
        "Has Natural Skin Colour":true,
        .....
     }

  } 


},
{"img":"image url",
  "QualityAttributes": {
    "ISO":{
     "Tinted Glasses":true,
      ......
     },
     "ISOBestPractice":{
        "Mouth Closed Best Practice":true,
         ......
     },
     "ICAO":{
        "No Dark Lenses and no heavy frames and no glares":true,
         ......
     },
     "DepartmentStandard":{
        "Has Natural Skin Colour":true,
        .....
     }

  } 


}

请帮我把它变成这样，我试过 field.toJSON 但它没有转换完整的 JSON

解决方案

你需要解析它。

var json = {
    "img":"imageurl",
    "qualityJsonString": "{\"MorphoScore\":\"204\",\"AwareScore\":\"0\",\"QualityCategory\":\"Medium\",\"QualityAttributes\":{\"ISO\":{\"Tinted Glasses\":true,\"Horizontally Centered

    };

var parsedQualityJSON = $.parseJSON(json.qualityJsonString);
console.log(parsedQualityJSON);

在该示例中，parsedQualityJSON变量包含新的 json 对象。

我确实删除了您的 Json 字符串的第二部分，因为它的格式不正确，但是由于与第一个相比缺少数据，我认为那是因为您复制它的方式，如果不是这样的话您需要检查您使用的 Json 字符串的注释。
