拉取数组对象值然后推送到另一个数组

Question

嗨！我正在尝试遍历一个对象以执行一个函数，该函数将读取每个分组数组中的每个值，但我继续只有第一组。

我试图迭代并将它添加到一个数组中，但我无法获得预期的结果。

这是预期的结果，但只返回第一个分组数组。

console.log ->
{
  "order_details": [
    {
      "order_seq": "2104150001"
    },
    {
      "order_seq": "2105110005"
    },
    {
      "order_seq": "2106220007"
    },
    {
      "order_seq": "2105260007"
    }
  ]
}

console.log ->
{
  "order_details": [
    {
      "order_seq": "2105270001"
    }
  ]
}

console.log ->
{
  "order_details": [
    {
      "order_seq": "2104090006"
    },
    {
      "order_seq": "2105060001"
    }
  ]
}

这是我的脚本 sn-p：

var objectPayload = {
  "0": [{
    "order_seq": "2104150001"
  }, {
    "order_seq": "2105110005"
  }, {
    "order_seq": "2106220007"
  }, {
    "order_seq": "2105260007"
  }],
  "1": [{
    "order_seq": "2105270001"
  }],
  "2": [{
    "order_seq": "2104090006"
  }, {
    "order_seq": "2105060001"
  }]
};

var result = Object.keys(objectPayload).map((key) => objectPayload[key]);

for (let i = 0; i < result.length; i++) {
  var testList = {
    "order_details": []
  };
  setTimeout(function() {
    let jsonSeqNo;
    result[i].map(function(value) {
      jsonSeqNo = {
        'order_seq': value.order_seq
      };
    });
    testList.order_details.push(jsonSeqNo);
    console.log(testList);
  }, i * 500);
}

解决方法很简单：

var objectPayload = {
  "0": [{
    "order_seq": "2104150001"
  }, {
    "order_seq": "2105110005"
  }, {
    "order_seq": "2106220007"
  }, {
    "order_seq": "2105260007"
  }],
  "1": [{
    "order_seq": "2105270001"
  }],
  "2": [{
    "order_seq": "2104090006"
  }, {
    "order_seq": "2105060001"
  }]
};

const result = Object.values(objectPayload).map((group) => ({
  order_details: group
}));

result.forEach(entry => console.log(entry));

使用Object.values，您将获得一组组。然后使用Array.prototype.flat 可以展平数组。
