Javascript 使用数组中的数据更改对象字段

对于数组中的每个用户，如果“isPrimary”设置为true，我希望获取他们的positionTitle，并使用此positionTitle替换对象中同一用户的所有positionTitle

两个数据集都有“全名”，我认为应该使用，因为可能有多个位置，这导致我认为不能使用positionID

我的代码确实替换了标题，但如果用户有多个位置，则代码不起作用

旁注：如果没有主位置，我希望使用阵列中用户的第一个位置

对象中的isPrimary基本上是无关的

我的目标：

graphData = {

  "name": "Annual meetings",
  "engagementAreas": [{
    "id": "1",
    "engagementTypes": [{
      "name": "forestry",
      "engagements": []
    },{
      "name": "houses",
      "engagements": [{
        "name": "engagement1",
        "members": [{
          "id": "e334", "account": {
            "id": "123", "fullName": "jim bean"
          },
          "position": {
            "id": "3434",
            "positionTitle": "Manager",
            "isPrimary": false
          }
        }]
      }]
    },{
      "name": "landscaping",
      "engagements": [{
        "name": "engagement1343",
        "members": [{
          "id": "e334", "account": {
            "id": "123", "fullName": "john boer"
          },
          "position": {
            "id": "4545",
            "positionTitle": "Managing Director",
            "isPrimary": true

          }
        },{
          "id": "5555", "account": {
            "id": "123", "fullName": "jim bean"
          },
          "position": {
            "id": "a16b0000004AxeBAAS",
            "positionTitle": "Managing Director",
            "isPrimary": true
          }
        }]
      }]
    }]

  },{

    "name": "community days",
    "engagementTypes": [{
      "name": "skyscraping",
      "engagements": []
    },{
      "name": "tennis",
      "engagements": [{
        "name": "engagement346",
        "members": [{
          "id": "34", "account": {
            "id": "0010X000048DDMsQAO", "fullName": "edy long"
          },
          "position": {
            "id": "3999434",
            "positionTitle": "Managing Director",
            "isPrimary": true
          }
        }]
      }]
    },{
      "name": "Juicing",
      "engagements": [{
        "name": "347343",
        "members": [{
          "id": "4546", "account": {
            "id": "001b000003WnPy1AAF", "fullName": "jeff bint"
          },
          "position": {
            "id": "35006",
            "positionTitle": "Senior Manager, Energy"

          }
        }]
      }]
    }]
  }]
}

注意Jim bean有两个位置。 我的数组，我要使用它的isPrimary:true位置标题：

IndividualData = [{
  "account": {
    "id": "23423",
    "fullName": "jim bean"
  },
  "positions": [{
    "id": "123",
    "organizationId": "001b0000005gxmlAAA",
    "organizationName": "a",
    "positionTitle": "Dalius Senior Manager, Energy",
    "positionLevel": "5-Middle Management & Advisers",
    "isPrimary": true,
    "startDate": "2016-10-07",
    "endDate": null
  }]
},{
  "account": {
    "id": "394838",
    "fullName": "jim bean"
  },
  "positions": [{
    "id": "a16b0000004AxeBAAS",
    "organizationId": "001b0000005gxmlAAA",
    "organizationName": "a",
    "positionTitle": "Head Recruiter",
    "positionLevel": "Senior Management",
    "isPrimary": false,
    "startDate": "2008-04-23",
    "endDate": null
  }]
},{
  "account": {
    "id": "001b000003WnPy1AAF",
    "fullName": "jeff bint"
  },
  "positions": [{
    "id": "a16b0000004AxeBAAS",
    "organizationId": "001b0000005gxmlAAA",
    "organizationName": "a",
    "positionTitle": "Senior Manager, Energy",
    "positionLevel": "5-Middle Management & Advisers",
    "isPrimary": true,
    "startDate": "2016-10-07",
    "endDate": null
  }]
}, {
  "account": {
    "id": "0010X000048DDMsQAO",
    "fullName": "edy long"
  },
  "positions": [{
    "id": "a160X000004nKfhQAE",
    "organizationId": "001b0000005gxmlAAA",
    "organizationName": "a",
    "positionTitle": "Managing Director",
    "positionLevel": "4-Head of Business Unit/Head of Region",
    "isPrimary": true,
    "startDate": "2018-03-05",
    "endDate": null
  }]
}, {
  "account": {
    "id": "123",
    "fullName": "john boer"
  },
  "positions": [{
    "id": "325345634634",
    "organizationId": "001b0000005gxmlAAA",
    "organizationName": "a",
    "positionTitle": "Managing Director",
    "positionLevel": "4-Head of Business Unit/Head of Region",
    "isPrimary": true,
    "startDate": "2018-03-05",
    "endDate": null
  }]
}]

Jim Bean在上面的数组中也有两个位置，但其中一个是主位置

我的代码当前确实替换了，但没有从数组中获取主代码，并更新同一用户的所有positionTitles：

const accountIdToPositionDict = IndividualData.reduce( (current, item) => {
  current[item.account.id] = (item.positions.filter( position => position.isPrimary )[0] || {} ).positionTitle;
  return current;
}, {} );

const updatedGraphTable = { ...graphData,
  engagementAreas: graphData.engagementAreas.map(area => ({ ...area,
    engagementTypes: area.engagementTypes.map(type => ({ ...type,
      engagements: type.engagements.map(engagement => ({ ...engagement,
        members: engagement.members.map(member => ({ ...member,
          position: { ...member.position,
            // use the found positionTitle, or the original one that was given
            positionTitle: member.account &&  accountIdToPositionDict[member.account.id] || member.position.positionTitle
          }
        }))
      }))
    }))
  }))
};

我的当前输出：

我不完全理解您的数据结构，但如果我假设：

• 个人数据.account.id

  不可靠

• IndividualData.account.fullName

  可靠

• IndividualData.account.positions

  是一个数组，每个

  IndividualData.account

我提出的解决方案是过滤

个人数据。帐户

s在使用reduce之前有一个主要位置，并在

全名

而不是

Id

上执行整个操作：

const accountIdToPositionDict = IndividualData
    .filter(item => item.positions.find(p => p.isPrimary))
    .reduce( (current, item) => {
        current[item.account.fullName] = (item.positions.find( position => position.isPrimary ) || {} ).positionTitle;
        return current;
     }, {} );

const updatedGraphTable = {
    //Long stuff to get to the relevant path...
    accountIdToPositionDict[member.account.fullName] || member.position.positionTitle
}

编辑 根据您的评论，如果用户在IndividualData中没有主位置，则必须将其位置设置为该用户在IndividualData中获得的第一个位置。在这种情况下，您可以删除我前面代码片段的过滤器部分，在reduce中使用以下方法：

• 如果当前项目具有主位置，则将其添加到当前[item.account.fullName]键中
• 否则，如果没有为当前项目的全名存储任何内容，请将其添加到

  当前[item.account.fullName]

  项中

  const accountIdToPositionDict = IndividualData
      .reduce((current, item) => {
          const primaryPosition = item.positions.find(p => p.isPrimary);
          if(!current[item.account.fullName] || primaryPosition)
              current[item.account.fullName] = 
                  (primaryPosition && primaryPosition.title) || 
                  item.positions[0].positionTitle;
      return current;
  }, {} );

是的，您是正确的，因此如果阵列中每个成员共享相同的帐户ID，则当前会将其主要位置替换为对象主要位置。但问题是我希望阵列中的主要位置替换为名称，以便我可以将其在对象中的所有位置作为目标。另一个问题是，一些用户没有主位置，在这种情况下，我想使用他们在数组中的第一个位置，这会更清楚吗？抱歉，我可能在发布时不清楚
