javascript - 复制具有特定值的对象

Question

我有一个场景，如果以下 json 中的价格大于 0，我需要复制报价(不含价格):

const data = [
    {
        "id": "offer1",
        "Identifier": {
            "info": "some info for offer1",
            "value": "some string for offer1"
        },
        "Price": {
            "Total": 94.30
        }
    },  
    {
        "id": "offer2",
        "Identifier": {
            "info": "some info for offer2",
            "value": "some string for offer2"
        },
        "Price": {
            "Total": 0.0
        }
    },
    {
        "id": "offer3",
        "Identifier": {
            "info": "some info for offer3",
            "value": "some string for offer3"
        },
        "Price": {
            "Total": 48.50
        }
    }
];

我需要获取所有价格 > 0 的报价并将它们放入具有特定格式的另一个数组中，预期结果应如下所示:

const result = [
  {
    "id":"offer1",
    "reference":"offer1",
    "Identifier":{
      "info":"some info for offer1",
      "value":"some string for offer1"
    }
  },
  {
    "id":"offer3",
    "reference":"offer3",
    "Identifier":{
      "info":"some info for offer3",
      "value":"some string for offer3"
    }
  }
]

我所做的第一步是过滤初始数据数组以排除 Total = 0 的报价。

const filteredOffers = data.filter(offer => offer.Price.Total > 0);

接下来我应该做什么才能得到预期的结果？ 谢谢。

您可以映射新对象。

const
    data = [{ id: "offer1", Identifier: { info: "some info for offer1", value: "some string for offer1" }, Price: { Total: 94.3 } }, { id: "offer2", Identifier: { info: "some info for offer2", value: "some string for offer2" }, Price: { Total: 0 } }, { id: "offer3", Identifier: { info: "some info for offer3", value: "some string for offer3" }, Price: { Total: 48.5 } }],
    result = data
        .filter(({ Price: { Total } }) => Total > 0)
        .map(({ Price, ...o }) => ({ ...o, reference: o.id }));

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
