Javascript - JSON - Вложение и группировка

Question

У меня есть следующий объект JSON, который мне нужен, чтобы разблокировать, перегруппировать и повторно разложить по состоянию. Я понимаю, что должен быть какой-то цикл for-loop и group by operation, который должен выполняться.

[ 
{ 
"Date": "2000-01-01T08:00:00.000Z", 
"Florida": "4626",

"California": "260663", 
"Nevada": "572", 
"": "" 
}, 
{ 
"Date": "2002-01-01T08:00:00.000Z", 
"Florida": "3634", 
"New York": "164", 
"Pennsylvania": "2324",

"West Virginia": "1456",

"Alaska South": "11303", 
"Arizona": "63", 
"California": "257898", 
"Nevada": "553", 
"": "" 
} 
] 

Я хотел бы обрабатывать выше, в следующем формате, где состояние ключ является состояние имя и ключ производство представляет собой массив словарей с годами и производства на этот год.

[ 
{ 
"state": "California", 
"production": [ 
    { 
    "Date": "2000-01-01T08:00:00.000Z", 
    "production": 1000 
    }, 
    { 
    "Date": "2001-01-01T08:00:00.000Z", 
    "production": 2000 
    } 
] 
}, 
{ 
"state": "New York", 
"production": [ 
    { 
    "Date": "2000-01-01T08:00:00.000Z", 
    "production": 4000 
    }, 
    { 
    "Date": "2001-01-01T08:00:00.000Z", 
    "production": 5000 
    } 
] 
} 
] 

Пожалуйста, дайте мне знать, какие операции необходимы для выполнения вышеуказанного формата. Спасибо!

Возможно, это работает для вас, с некоторой итерацией и объектом в качестве ссылки.

var data = [{ "Date": "2000-01-01T08:00:00.000Z", "Florida": "4626", "New York": "210", "Pennsylvania": "1500", "Virginia": "9", "West Virginia": "1400", "Illinois": "12206", "Indiana": "2098", "Kansas": "34463", "Kentucky": "3465", "Michigan": "7907", "Missouri": "94", "Nebraska": "2957", "North Dakota": "32719", "Ohio": "6575", "Oklahoma": "69976", "South Dakota": "1170", "Tennessee": "346", "Alabama": "10457", "Arkansas": "7154", "Louisiana": "105425", "Mississippi": "19844", "New Mexico": "67198", "Texas": "443397", "Colorado": "18481", "Montana": "15428", "Utah": "15636", "Wyoming": "60726", "Alaska": "355199", "Alaska South": "10590", "Arizona": "59", "California": "271132", "Nevada": "621", "": "" }, { "Date": "2001-01-01T08:00:00.000Z", "Florida": "4426", "New York": "166", "Pennsylvania": "1620", "Virginia": "11", "West Virginia": "1226", "Illinois": "10092", "Indiana": "2022", "Kansas": "33942", "Kentucky": "2969", "Michigan": "7375", "Missouri": "91", "Nebraska": "2922", "North Dakota": "31691", "Ohio": "6051", "Oklahoma": "68531", "South Dakota": "1255", "Tennessee": "351", "Alabama": "9334", "Arkansas": "7592", "Louisiana": "104610", "Mississippi": "19528", "New Mexico": "68001", "Texas": "424297", "Colorado": "16520", "Montana": "15920", "Utah": "15252", "Wyoming": "57433", "Alaska": "351411", "Alaska South": "11500", "Arizona": "59", "California": "260663", "Nevada": "572", "": "" }, { "Date": "2002-01-01T08:00:00.000Z", "Florida": "3634", "New York": "164", "Pennsylvania": "2324", "Virginia": "25", "West Virginia": "1456", "Illinois": "11100", "Indiana": "1962", "Kansas": "33380", "Kentucky": "2721", "Michigan": "7218", "Missouri": "95", "Nebraska": "2782", "North Dakota": "30803", "Ohio": "5631", "Oklahoma": "66421", "South Dakota": "1214", "Tennessee": "275", "Alabama": "8636", "Arkansas": "7252", "Louisiana": "93321", "Mississippi": "19371", "New Mexico": "67562", "Texas": "405776", "Colorado": "20522", "Montana": "16990", "Utah": "13771", "Wyoming": "54801", "Alaska": "359382", "Alaska South": "11303", "Arizona": "63", "California": "257898", "Nevada": "553", "": "" }], 
 
    grouped = []; 
 

 
data.forEach(function (a) { 
 
    Object.keys(a).forEach(function (k) { 
 
     if (k !== 'Date') { 
 
      if (!this[k]) { 
 
       this[k] = { state: k, production: [] }; 
 
       grouped.push(this[k]); 
 
      } 
 
      this[k].production.push({ Date: a.Date, production: a[k] }); 
 
     } 
 
    }, this); 
 
}, Object.create(null)); 
 

 
document.write('<pre>' + JSON.stringify(grouped, 0, 4) + '</pre>');
