Question

我已经分配了一个任务，使用下划线js对角度js中的数据进行分组。

我的JSON：

 data = [   
        {
          "Building*": "Building A",
          "Wing*": "Wing C",
          "Floor*": "Floor 3",
          "Room Name*": "Room 3",
          "Room Type*": "AC",
          "Location*": "Location 1",
          "Device ID*": 27,
          "Category*": "Soap Hygene",
          "Dispenser Name*": "Dispenser 34",
          "Type*": "Manual",
          "Cartridge Type*": "Type 1",
          "Date of installation": "2016-04-11T06:06:22 -06:-30",
          "Contact Last Name": "Maynard",
          "Email Address": "thomas.boscher@gmail.com",
          "Mobile Number with country code": "+1 (949) 590-3465",
          "Description": "Description of device",
          "Model": 37
        },
        {
          "Building*": "Building B",
          "Wing*": "Wing B",
          "Floor*": "Floor 3",
          "Room Name*": "Room 1",
          "Room Type*": "AC",
          "Location*": "Location 3",
          "Device ID*": 26,
          "Category*": "Soap Hygene",
          "Dispenser Name*": "Dispenser 33",
          "Type*": "Manual",
          "Cartridge Type*": "Type 2",
          "Date of installation": "2015-07-24T12:42:24 -06:-30",
          "Contact Last Name": "Holland",
          "Email Address": "thomas.boscher@gmail.com",
          "Mobile Number with country code": "+1 (947) 491-2353",
          "Description": "Description of device",
          "Model": 32
        }         

      ]

我需要以下格式的数据，其中每个建筑细节都包含机翼和地板数据

  updateData = [{ 
    building: 'Building A' , 
    buildingData:[ {
        wing: "Wing A",
         wingData: [{
          floor:'Floor 2',
          floorData:[{
            room:'Room 3',
            roomData:[]
            }]
          }]
        }]
  }];

我试过了：

但它失败了。需要帮忙。提前谢谢。

根据我的理解，您希望以下列嵌套顺序进行groupBy：

建筑 - ＆gt;＆gt;翼 - ＆gt;＆gt;楼层 - ＆gt;＆gt;间

您可以尝试通过传递您想要groupBy的嵌套属性顺序的数组来递归地调用groupBy（或循环遍历您）。请尝试下面的代码段：

const nestedOrder = ['Building*', 'Wing*', 'Floor*', 'Room Name*']

function groupFilter (rawData, attrList) {
  if (attrList.length == 0) return rawData

  var currentAttr = _(attrList).first()
  return _(rawData)
    .chain()
    .groupBy(currentAttr)
    .map((list, attrName) => Object({
      [currentAttr]: attrName,
      [`${currentAttr}Data`]: groupFilter(list, _(attrList).rest())
    }))
    .value()
}

console.log(groupFilter(data, nestedOrder))

然后将原始数据压缩到最深的嵌套属性，在这种情况下，“房间名称”，然后您可以编写自定义过滤器以输出您希望RoomData保留的内容。

不确定它是否是正确的方法，但如果运行时不是一个大问题，那么我认为你可以使它正常工作。

希望这对你有所帮助。
