如何合并子数组中的对象，使得在javascript中只剩下一个数组中有多个对象

Question

我有下面的数组在数组1看到完整，我需要每个子数组合并其中的对象，这样它就像这样。

数组FINAL

[
  {"col0":"glasses","col1":"Milky glasses","col2":"292516467012796941"}
  , ...
]

因此最终结果是一个包含6个对象的数组。上面的...代表其余的对象。

我试过[].concat.apply([],array)，但它并不完全符合我的要求。我将在数组2的数组下面发布它的操作

阵列1

[
  [
    {
      "col0": "Glasses"
    },
    {
      "col1": "Milky Glasses"
    },
    {
      "col2": "292516467012796941"
    }
  ],
  [
    {
      "col0": "Knives"
    },
    {
      "col1": "Milky Knives"
    },
    {
      "col2": "292516484536599049"
    }
  ],
  [
    {
      "col0": "Forks"
    },
    {
      "col1": "Milky Forks"
    },
    {
      "col2": "292516497196057096"
    }
  ],
  [
    {
      "col0": "Gloves"
    },
    {
      "col1": "Kewl Gloves"
    },
    {
      "col2": "292534063457108493"
    }
  ],
  [
    {
      "col0": "Wrench"
    },
    {
      "col1": "Kewl Wrench"
    },
    {
      "col2": "292534088244396552"
    }
  ],
  [
    {
      "col0": "Monkey snake"
    },
    {
      "col1": "Kewl Monkey snake"
    },
    {
      "col2": "292534109863936521"
    }
  ]
]

这是我不想要的输出，但到目前为止我所能做的一切。在ARRAY FINAL的顶部看到我想要的输出

阵列2

[
  {
    "col0": "Glasses"
  },
  {
    "col1": "Milky Glasses"
  },
  {
    "col2": "292516467012796941"
  },
  {
    "col0": "Knives"
  },
  {
    "col1": "Milky Knives"
  },
  {
    "col2": "292516484536599049"
  },
  {
    "col0": "Forks"
  },
  {
    "col1": "Milky Forks"
  },
  {
    "col2": "292516497196057096"
  },
  {
    "col0": "Gloves"
  },
  {
    "col1": "Kewl Gloves"
  },
  {
    "col2": "292534063457108493"
  },
  {
    "col0": "Wrench"
  },
  {
    "col1": "Kewl Wrench"
  },
  {
    "col2": "292534088244396552"
  },
  {
    "col0": "Monkey snake"
  },
  {
    "col1": "Kewl Monkey snake"
  },
  {
    "col2": "292534109863936521"
  }
]

感谢您提前提供的帮助

Answer 1

可以这样完成，使用arr作为原始数组-

for (let i = 0; i < arr.length; i++) {
  let res = {}, subArr = arr[i];
  subArr.forEach((a,ind) => {
Object.assign(res,subArr[0],subArr[1],subArr[2]);
  });
  arr[i] = res;
}

Answer 2

您可以映射数组并展开对象以获得单个对象。

null

const
    data = [[{ col0: "Glasses" }, { col1: "Milky Glasses" }, { col2: 292516467012796900 }], [{ col0: "Knives" }, { col1: "Milky Knives" }, { col2: 292516484536599040 }], [{ col0: "Forks" }, { col1: "Milky Forks" }, { col2: 292516497196057100 }], [{ col0: "Gloves" }, { col1: "Kewl Gloves" }, { col2: 292534063457108500 }], [{ col0: "Wrench" }, { col1: "Kewl Wrench" }, { col2: 292534088244396540 }], [{ col0: "Monkey snake" }, { col1: "Kewl Monkey snake" }, { col2: 292534109863936500 }]],
    result = data.map(a => Object.assign({}, ...a));
    
console.log(result);
