javascript - 将 JSON 字符串转换为另一种格式

Question

我有一个如下格式的json，我想把这个json转换成问题末尾提到的格式。我只想使用 javascript 来执行此转换，而不是任何其他工具，如 Gson 或服务端 Java 代码。请让我知道这是如何实现的。

 [{
    "innNumber": {
        "id": "0111",
        "idAsLong": 111,
        "idWithoutZero": "111"
    },
    "nightlyRates": [{
        "date": "2017-02-09",
        "nightlyRate": {
            "amount": 155.85,
            "currencyCode": "CAD"
        },
        "points": 0
    }]
}, {
    "innNumber": {
        "id": "0111",
        "idAsLong": 111,
        "idWithoutZero": "111"
    },
    "nightlyRates": [{
        "date": "2017-02-09",
        "nightlyRate": {
            "amount": 155.85,
            "currencyCode": "CAD"
        },
        "points": 0
    }]

}]

JSON 响应应采用以下要求的格式。

    [{"hotelRoomRate":{
    "innNumber": {
        "id": "0111",
        "idAsLong": 111,
        "idWithoutZero": "111"
    },
    "nightlyRates": [{
        "date": "2017-02-09",
        "nightlyRate": {
            "amount": 155.85,
            "currencyCode": "CAD"
        },
        "points": 0
    }]

  } 
}, 
{"hotelRoomRate":
  {
    "innNumber": {
        "id": "0111",
        "idAsLong": 111,
        "idWithoutZero": "111"
    },
    "nightlyRates": [{
        "date": "2017-02-09",
        "nightlyRate": {
            "amount": 155.85,
            "currencyCode": "CAD"
        },
        "points": 0
    }]

}   
}]

Answer 1

一个简单的map()会做的

var res = data.map(function(item){
   return { hotelRoomRate : item};
});
