Question

下面是我的尝试，我有一个对象，其中包含对象数组，其中包含一个字段：“ positionTitle”。

我还有一个对象数组，其中也有一个'positionTitle'

它们都具有相似的数据，我希望我的“ individualsData”中所有positionTitles的值都进入“ graphData”，并且现在能够使用此新的graphData！

我认为我的尝试是错误的，将它们都视为数组？

谢谢，戴尔

graphData = {
  "engagementAreas": [{
    "id": "1",
    "engagementTypes": [{
        "name": "forestry",
        "engagements": []
      },
      {
        "name": "houses",
        "engagements": [{
          "name": "engagement1",
          "members": [{
            "position": {
              "id": "3434",
              "positionTitle": "Manager"
            }
          }]
        }]
      }
    ]
  }]
}, {

  "engagements": [{
    "name": "engagement1343",
    "members": [{
      "position": {
        "id": "4545",
        "positionTitle": "Senior Manager"

      }
    }]
  }]
}

IndividualData = [{
  "account": {

    "isPrimary": true,
    "startDate": "2016-10-07",
    "endDate": null
  }]
}, {

    "isPrimary": true,

}

What I expect to see:  

 NEWgraphData = {
  "engagementAreas": [{
    "id": "1",
    "engagementTypes": [{
        "name": "forestry",
        "engagements": []
      },
      {
        "name": "houses",
        "engagements": [{
          "name": "engagement1",
          "members": [{
            "position": {
              "id": "3434",
              "positionTitle": "Senior Manager, Energy" <== from individualsdata
            }
          }]
        }]
      }
    ]
  }]
}, {
  "name": "landscaping",
  "engagements": [{
    "name": "engagement1343",
    "members": [{
      "position": {
        "id": "4545",
        "positionTitle": "Managing Director" <== also from individuals data

      }
    }]
  }]
}

graphData.engagementAreas.map((el, i) => {
  el.engagementTypes.engagements.members.position.positionTitle = individualsData.positions.positionTitle;
  return el;
})
