javascript - 将对象数组合并为单个对象数组

Question

我正在寻找将对象数组合并到单个对象数组中，并将对象键附加到内部对象键中的每个键

我有类似的对象

    var myObj = {
                "Details": [{
                        "car": "Audi",
                        "price": 40000,
                        "color": "blue"
                    },
                    {
                        "car": "BMW",
                        "price": 35000,
                        "color": "black"
                    }
                ],
                "Accounts": [{
                        "Total": 2000
                    },
                    {
                        "Total": 3000
                    }
                ]
            }

并且键和对象的长度未知，我想像这样合并它

[
          {
            "Detailscar": "Audi",
            "Detailsprice": 40000,
            "Detailscolor": "blue",
            "AccountsTotal": 2000
          },
          {
            "Detailscar": "BMW",
            "Detailsprice": 35000,
            "Detailscolor": "black",
            "AccountsTotal": 3000
          }
        ]

我尝试过 Ramda mergeAll，但它在我的情况下不起作用，因为它只合并对象

这是我尝试过的

 var mergedArray = []
        R.mapObjIndexed((instance, instanceName) => {
            mergedArray.push(R.map((innerObj) => {
                var customObject = {};
                R.forEach((key) => {
                    customObject[`${instanceName}${key}`] = innerObj[key]
                }, Object.keys(innerObj))
                return customObject;
            }, instance))
        }, myObj)

我正在尝试将每个修改后的对象添加到 mergeArray 数组中，但它会为每次迭代添加，最后，它会创建 2 个数组

mergedArray 仍在创建两个不同的数组，其中对象的键将附加到对象的属性中，但我希望将其合并到单个对象数组中。

我错过了一些东西。我应该怎么做才能解决这个问题？

提出一些帮助。

使用Array.prototype.map并将索引作为第二个参数传递给其回调以从 Account 对象获取元素

const data = {
  "Details": [
    {
      "car": "Audi",
      "price": 40000,
      "color": "blue"
    },
    {
      "car": "BMW",
      "price": 35000,
      "color": "black"
    },
    {
      "car": "Porsche",
      "price": 60000,
      "color": "green"
    }

  ],
  "Accounts": [
    {
      "Total": 2000
    },
    {
      "Total": 3000
    },
    {
      "Total": 3000
    }

  ]
};

const mergeCarData = ({ Details, Accounts} = {}) => {
  return Details.length === Accounts.length ? Details.map(({ car, price, color}, idx) => ({
    Detailscar: car,
    Detailsprice: price,
    Detailscolor: color,
    AccountsTotal: Accounts[idx].Total
  })) : [];
};

console.log(mergeCarData(data));
