如何将Locations[0]作为Sku字段填充到Locations[1]的数组对象中？

原始输入数据 #

[{
    "Locations": ["TP-401176509", [{
      "WarehouseCode": "01",
      "LocationCode": "A-04B01-B",
      "Quantity": 1,
      "Reserve": false
    }, {
      "WarehouseCode": "01",
      "LocationCode": "A-04B02-A",
      "Quantity": 1,
      "Reserve": false
    }, {
      "WarehouseCode": "01",
      "LocationCode": "A-04B13-A",
      "Quantity": 1,
      "Reserve": false
    }]]
}]

预期输出格式 #

[{
    "Sku": "TP-401176509",
    "WarehouseCode": "01",
    "LocationCode": "A-04B01-B",
    "Quantity": 1,
    "Reserve": false
  }, {
    "Sku": "TP-401176509",
    "WarehouseCode": "01",
    "LocationCode": "A-04B02-A",
    "Quantity": 1,
    "Reserve": false
  }, {
    "Sku": "TP-401176509",
    "WarehouseCode": "01",
    "LocationCode": "A-04B13-A",
    "Quantity": 1,
    "Reserve": false
  }]

实现代码 #

const rawData = [{
    "Locations": ["TP-401176509", [{
      "WarehouseCode": "01",
      "LocationCode": "A-04B01-B",
      "Quantity": 1,
      "Reserve": false
    }, {
      "WarehouseCode": "01",
      "LocationCode": "A-04B02-A",
      "Quantity": 1,
      "Reserve": false
    }, {
      "WarehouseCode": "01",
      "LocationCode": "A-04B13-A",
      "Quantity": 1,
      "Reserve": false
    }]]
}];

const transformedData = rawData.flatMap(item => {
  const sku = item.Locations[0];
  const locations = item.Locations[1];
  return locations.map(location => ({
    Sku: sku,
    ...location
  }));
});

console.log(transformedData);

代码说明 #

• 用flatMap遍历原始数组，同时展开结果数组，避免嵌套结构；
• 从每个Locations数组中提取SKU（item.Locations[0]）和位置详情列表（item.Locations[1]）；
• 通过map给每个位置对象添加Sku字段，同时保留原有属性。

如果原始数据包含多个SKU条目，该逻辑会自动处理所有条目并合并结果。
