JavaScript数据处理（对象数组操作生成新数组）

a1chemy

我的表单提交的原数据格式是这样的：

{
    "task_number": "开发测试大任务编号",
    "task_name": "开发测试大任务名称",
    "task_desc": "开发测试任务说明",
    "task_node": [
        {
            "id": 0,
            "created_at": null,
            "updated_at": null,
            "deleted_at": null,
            "task_id": 0,
            "node_code": "1-2-1",
            "node_name": "测试子任务编号",
            "node_start": "2022-10-01 08:00:00",
            "node_end": "2022-10-15 08:00:00",
            "node_num": 2,
            "node_subject": "乡镇纪委领导班子",
            "node_desc": "暂无",
            "node_demand": "测试子任务编号",
            "node_attach_num": 3,
            "time": [
                "2022-10-01T00:00:00.000Z",
                "2022-10-15T00:00:00.000Z"
            ],
            "task_filling": [
                "{\"full_name\":\"张飞\",\"user_id\":20}",
                "{\"full_name\":\"王林\",\"user_id\":26}"
            ]
        },
        {
            "id": 0,
            "created_at": null,
            "updated_at": null,
            "deleted_at": null,
            "task_id": 0,
            "node_code": "1-2-1",
            "node_name": "测试子任务编号",
            "node_start": "2022-10-01 08:00:00",
            "node_end": "2022-10-15 08:00:00",
            "node_num": 2,
            "node_subject": "乡镇纪委领导班子",
            "node_desc": "暂无",
            "node_demand": "测试子任务编号",
            "node_attach_num": 3,
            "time": [
                "2022-10-01T00:00:00.000Z",
                "2022-10-15T00:00:00.000Z"
            ],
            "task_filling": [
                "{\"full_name\":\"韩信\",\"user_id\":22}",
                "{\"full_name\":\"李白\",\"user_id\":21}"
            ]
        }
    ]
}

现在后端需要的格式是这样的：

{
  "task_number": "开发测试大任务编号",
  "task_name": "开发测试大任务名称",
  "task_desc": "开发测试任务说明",
  "task_filling": [
    "{\"full_name\":\"张飞\",\"user_id\":20}",
    "{\"full_name\":\"王林\",\"user_id\":26}"
]
  "task_node": [
      {
          "id": 0,
          "created_at": null,
          "updated_at": null,
          "deleted_at": null,
          "task_id": 0,
          "node_code": "1-2-1",
          "node_name": "测试子任务编号",
          "node_start": "2022-10-01 08:00:00",
          "node_end": "2022-10-15 08:00:00",
          "node_num": 2,
          "node_subject": "乡镇纪委领导班子",
          "node_desc": "暂无",
          "node_demand": "测试子任务编号",
          "node_attach_num": 3,
          "time": [
              "2022-10-01T00:00:00.000Z",
              "2022-10-15T00:00:00.000Z"
          ],
         
      },
      
  ]
},
{
  "task_number": "开发测试大任务编号",
  "task_name": "开发测试大任务名称",
  "task_desc": "开发测试任务说明",
  "task_filling": [
   "{\"full_name\":\"韩信\",\"user_id\":22}",
   "{\"full_name\":\"李白\",\"user_id\":21}"
]
  "task_node": [
      {
          "id": 0,
          "created_at": null,
          "updated_at": null,
          "deleted_at": null,
          "task_id": 0,
          "node_code": "1-2-1",
          "node_name": "测试子任务编号",
          "node_start": "2022-10-01 08:00:00",
          "node_end": "2022-10-15 08:00:00",
          "node_num": 2,
          "node_subject": "乡镇纪委领导班子",
          "node_desc": "暂无",
          "node_demand": "测试子任务编号",
          "node_attach_num": 3,
          "time": [
              "2022-10-01T00:00:00.000Z",
              "2022-10-15T00:00:00.000Z"
          ],
         
      },
      
  ]
}

就是要把task_node里的task_filling放到外面，根据task_node下的数量生成对应数量的新数组。还请各位大佬帮帮忙，非常感谢！
