JavaScript Json 解析器

Question

我正在尝试仅使用 javascript 编写 JSON 解析器。我只想使用 javascript 的原因是我想解析从 Meteor 服务器端的 API 返回的结果。但是，我在解析它时遇到了麻烦。下面是返回的 JSON:

{
   "R_5N4205x1hhF6pGZ":{
      "ResponseSet":"Default Response Set",
      "Name":"Anonymous",
      "ExternalDataReference":"",
      "EmailAddress":"",
      "Status":"16",
      "StartDate":"2014-01-09 11:19:51",
      "EndDate":"2014-01-09 11:19:56",
      "Finished":"1",
      "Q1":"Hello "
   },
   "R_7mqYPn4rZfNtVif":{
      "ResponseSet":"Default Response Set",
      "Name":"Anonymous",
      "ExternalDataReference":"",
      "EmailAddress":"",
      "Status":"16",
      "StartDate":"2014-01-09 11:21:58",
      "EndDate":"2014-01-09 11:22:05",
      "Finished":"1",
      "Q1":"Name identifier"
   },
   "R_bHs2h06HSQ1h2Qh":{
      "ResponseSet":"Default Response Set",
      "Name":"Anonymous",
      "ExternalDataReference":"",
      "EmailAddress":"",
      "Status":"16",
      "StartDate":"2014-01-09 11:28:24",
      "EndDate":"2014-01-09 11:28:30",
      "Finished":"1",
      "Q1":"Test"
   },
   "R_20rlmxxgGkYnWWF":{
      "ResponseSet":"Default Response Set",
      "Name":"Some, Name",
      "ExternalDataReference":"",
      "EmailAddress":"",
      "Status":"0",
      "StartDate":"2014-01-09 12:21:15",
      "EndDate":"2014-01-09 12:21:27",
      "Finished":"1",
      "Q1":"hjjhhjhj"
   },
   "R_e36yuRbnMmh38dD":{
      "ResponseSet":"Default Response Set",
      "Name":"Anonymous",
      "ExternalDataReference":"",
      "EmailAddress":"",
      "IPAddress":"161.185.153.4",
      "Status":"0",
      "StartDate":"2014-01-09 12:23:04",
      "EndDate":"2014-01-09 12:23:11",
      "Finished":"1",
      "Q1":"hello world "
   }
}

我想使用对象父键作为键“responseID”保存每个响应对象:值(即array[“responseID”] =“R_e36yuRbnMmh38dD”)

  "R_e36yuRbnMmh38dD":{
      "ResponseSet":"Default Response Set",
      "Name":"Anonymous",
      "ExternalDataReference":"",
      "EmailAddress":"",
      "IPAddress":"161.185.153.4",
      "Status":"0",
      "StartDate":"2014-01-09 12:23:04",
      "EndDate":"2014-01-09 12:23:11",
      "Finished":"1",
      "Q1":"hello world "
   }

我想将结果集保存在 mongoDb 中。

Answer 1

您可以使用 NodeJS JSON.parse() 函数，但如果我理解您想要更多地使用对象中的键创建一个对象。

这是代码，如果这是您想要做的:

var originalObject;
var resultArray;
for (var key in originalObject) {
   if(originalObject.hasOwnProperty(key )){
     var obj = originalObject[key];
     obj.responseID = key;
     resultArray.push(obj);
   }
}

但是你的问题有点令人困惑。对于 mongoDB，我建议 nodejs native driver
