javascript - 使用 lodash 根据条件过滤对象数组中的数据

Question

我有下面的对象集数组，我需要使用 lodash 根据条件从整个数组集中获取其中的一些对象。

我在lodash中使用了_.filter(data, condition)，但预期结果不是 future 。

有人帮我解决这个问题吗？

条件:EarnCode < 90 && 小时 === 0(结果将跳过这些数据)。

请求数组集:

[
  {
    "id" : 1,
    "EmpId" : 100,
    "AcctCode" : "2001-00",
    "SuperID" : 2000,
    "ReportNo" : "20180213.2015-06.2768.6",
    "EarnCode" : 96,
    "Hours" : 0
  },
 {
    "id" : 3,
    "EmpId" : 100,
    "AcctCode" : "2001-00",
    "SuperID" : 2000,
    "ReportNo" : "20180213.2015-06.2768.6",
    "EarnCode" : 96,
    "Hours" : 0
  },
  {
    "id" : 2,
    "EmpId" : 100,
    "AcctCode" : "2001-00",
    "SuperID" : 2000,
    "ReportNo" : "20180213.2015-06.2768.6",
    "EarnCode" : 1,
    "Hours" : 0
  },
  {
    "id" : 5,
    "EmpId" : 100,
    "AcctCode" : "2001-00",
    "SuperID" : 2000,
    "ReportNo" : "20180213.2015-06.2768.6",
    "EarnCode" : 1,
    "Hours" : 3
  }
]

预期结果:

[
{
        "id" : 1,
        "EmpId" : 100,
        "AcctCode" : "2001-00",
        "SuperID" : 2000,
        "ReportNo" : "20180213.2015-06.2768.6",
        "EarnCode" : 96,
        "Hours" : 0
      },
{
        "id" : 3,
        "EmpId" : 100,
        "AcctCode" : "2001-00",
        "SuperID" : 2000,
        "ReportNo" : "20180213.2015-06.2768.6",
        "EarnCode" : 96,
        "Hours" : 0
      },
 {
        "id" : 5,
        "EmpId" : 100,
        "AcctCode" : "2001-00",
        "SuperID" : 2000,
        "ReportNo" : "20180213.2015-06.2768.6",
        "EarnCode" : 1,
        "Hours" : 3
      }
]

为了完整起见，如果您坚持必须使用 lodash，请遵循 CRice 的答案，这可能是解决此问题的方法:

const inputSet = [{
  "id": 1,
  "EmpId": 100,
  "AcctCode": "2001-00",
  "SuperID": 2000,
  "ReportNo": "20180213.2015-06.2768.6",
  "EarnCode": 96,
  "Hours": 0
}, {
  "id": 3,
  "EmpId": 100,
  "AcctCode": "2001-00",
  "SuperID": 2000,
  "ReportNo": "20180213.2015-06.2768.6",
  "EarnCode": 96,
  "Hours": 0
}, {
  "id": 2,
  "EmpId": 100,
  "AcctCode": "2001-00",
  "SuperID": 2000,
  "ReportNo": "20180213.2015-06.2768.6",
  "EarnCode": 1,
  "Hours": 0
}, {
  "id": 5,
  "EmpId": 100,
  "AcctCode": "2001-00",
  "SuperID": 2000,
  "ReportNo": "20180213.2015-06.2768.6",
  "EarnCode": 1,
  "Hours": 3
}]

// Negate your condition, filter keeps items where the condition is
// true, so for your example, you need either Hours to be non-zero
// OR for EarnCode to be greater than 90.
const resultSet = _.filter(inputSet, i => i.Hours !== 0 || i.EarnCode >= 90);
console.log(resultSet); // Includes items 1, 3, and 5.
