对象数组过滤并获取另一个结构中的值

Question

我有数据作为对象数组，我应该过滤数据并获取带有值的对象和最小键，我尝试过循环和过滤器，但我无法按预期获得。 我已经分享了我拥有的数据和预期的结构，找到下面的代码，请帮助我。

我有以下数据：

var data = [
  {
    "Id": 1392236,
    "foldId": 410176,
    "binding": [
      {
        "assayType": "binding",
        "activityValue": 0.03,
        "strId": 1392236
      },
      {
        "assayType": "binding",
        "activityValue": 5.0,
        "strId": 1392236
      }
    ],
    "functional invitro": [
      {
        "assayType": "functional invitro",
        "activityValue": 0.03,
        "strId": 1392236
      },
      {
        "assayType": "functional invitro",
        "activityValue": 5.0,
        "strId": 1392236
      },
      
    ],
    "functionalInvivo": [
      {
        "assayType": "functional invivo",
        "activityValue": 45.0,
        "strId": 1392236
      },
      {
        "assayType": "functional invivo",
        "activityValue": 54.0,
        "strId": 1392236
      }
    ],
    "pharmacokinetics": [
      {
        "assayType": "pharmacokinetics",
        "activityValue": 10.67,
        "strId": 1392236
      },
      {
        "assayType": "pharmacokinetics",
        "activityValue": 2.6,
        "strId": 1392236
      }          
    ]
  },
  {
    "Id": 1392543,
    "foldId": 410176,
    "binding": [
      {
        "assayType": "binding",
        "activityValue": 0.38,
        "strId": 1392543
      },
      {
        "assayType": "binding",
        "activityValue": 4.3,
        "strId": 1392543
      }
      
    ],
    "functional invitro": [
      {
        "assayType": "functional invitro",
        "activityValue": 2.03,
        "strId": 1392543
      },
      {
        "assayType": "functional invitro",
        "activityValue": 3.0,
        "strId": 1392543
      },
      
    ],
    "functionalInvivo": [
      {
        "assayType": "functional invivo",
        "activityValue": 25.0,
        "strId": 1392543
      },
      {
        "assayType": "functional invivo",
        "activityValue": 64.0,
        "strId": 1392543
      }
    ],
    "pharmacokinetics": [
      {
        "assayType": "pharmacokinetics",
        "activityValue": 30.67,
        "strId": 1392543
      },
      {
        "assayType": "pharmacokinetics",
        "activityValue": 5.6,
        "strId": 1392543
      }          
    ]
  }
]

过滤后期待如下：

var filterData = [
  {
      "assayType": "binding",
      "activityValue": 0.03,
      "strId": 1392543
  },
  {
      "assayType": "functional invitro",
      "activityValue": 5.0,
      "strId": 1392543
  },
  {
      "assayType": "binding",
      "activityValue": 4.3,
      "strId": 1392236
  },
  {
      "assayType": "pharmacokinetics",
      "activityValue": 6.06,
      "strId": 1392543
  },
  {
      "assayType": "functional invivo",
      "activityValue": 64,
      "strId": 1392543
  },
  {
      "assayType": "functional invivo",
      "activityValue": 4,
      "strId": 1392236
  },
  {
      "assayType": "pharmacokinetics",
      "activityValue": 6.06,
      "strId": 1392236
  },
]

帮我解决。

Answer 1

您可以为此使用filter 、 map和flat方法，

data.map((item) => {
  return Object.keys(item).filter(key=> item[key].length).map((key) => item[key]).flat()
}).flat()

如果您需要进一步过滤数据，您可以在平面阵列上执行此操作。

Answer 2

您可以从对象中获取一些不需要的属性并迭代映射最小属性的值。

 const data = [{ Id: 1392236, foldId: 410176, binding: [{ assayType: "binding", activityValue: 0.03, strId: 1392236 }, { assayType: "binding", activityValue: 5, strId: 1392236 }], "functional invitro": [{ assayType: "functional invitro", activityValue: 0.03, strId: 1392236 }, { assayType: "functional invitro", activityValue: 5, strId: 1392236 }], functionalInvivo: [{ assayType: "functional invivo", activityValue: 45, strId: 1392236 }, { assayType: "functional invivo", activityValue: 54, strId: 1392236 }], pharmacokinetics: [{ assayType: "pharmacokinetics", activityValue: 10.67, strId: 1392236 }, { assayType: "pharmacokinetics", activityValue: 2.6, strId: 1392236 }] }, { Id: 1392543, foldId: 410176, binding: [{ assayType: "binding", activityValue: 0.38, strId: 1392543 }, { assayType: "binding", activityValue: 4.3, strId: 1392543 }], "functional invitro": [{ assayType: "functional invitro", activityValue: 2.03, strId: 1392543 }, { assayType: "functional invitro", activityValue: 3, strId: 1392543 }], functionalInvivo: [{ assayType: "functional invivo", activityValue: 25, strId: 1392543 }, { assayType: "functional invivo", activityValue: 64, strId: 1392543 }], pharmacokinetics: [{ assayType: "pharmacokinetics", activityValue: 30.67, strId: 1392543 }, { assayType: "pharmacokinetics", activityValue: 5.6, strId: 1392543 }] }], result = data.flatMap(({ Id, foldId, ...o }) => Object.values(o).map(array => array.reduce((a, b) => a.activityValue < b.activityValue ? a : b) ) ); console.log(result);
