使用递归函数将对象转换为特定格式

Question

原始对象：{ Name：'ZoneName'，Value：'Box A'，}，{ Name：'AirSide'，Value：{ JZCleanTipFlowResults：{ LeakageAirFlowRate: 2.0519336991674058，LeakageAirFlowRate_Uncertainty: 0.05755421849942835，LeakageAirFlowRate_lbmhr: 16285.188088630204，LeakageAirFlowRate_lbmhr_Uncertainty: 456.779511900225，}，UsedAmbientTemperatureForCombustion: true，SubStoichWarning: false，}，}，{ Name：'FuelSide'，取值：{ Fuels：{ 'Header 0'：{ CleanTipResults：{ HR: 10776333.422366736，HR_Uncertainty: 14383.420657232984，HR_MMBTUhr: 36.77037592294784，}，}，}，CleanTipResults：{ HR: 10776333.422366736，HR_Uncertainty: 14383.420657232984，}，

想要像这样的对象：

命名形状：{名称：‘'AirSide|JZCleanTipFlowResults|LeakageAirFlowRate_Uncertainty'，名称’，值：'Box A'，}，{名称：'AirSide|JZCleanTipFlowResults|LeakageAirFlowRate'，值: 2.0519336991674058，}，{名称：‘AirSide|JZCleanTipFlowResults|LeakageAirFlowRate_Uncertainty’，值: 0.05755421849942835，}，{名称：'AirSide|JZCleanTipFlowResults|LeakageAirFlowRate_lbmhr'，值: 16285.188088630204，}，{名称：'AirSide|JZCleanTipFlowResults|LeakageAirFlowRate_lbmhr_Uncertainty'，值: 456.779511900225，}，{名称：'AirSide|UsedAmbientTemperatureForCombustion'，值: true，}，{名称：'AirSide|JZCleanTipFlowResults|SubStoichWarning'，值: false，}，{ Name：'FuelSide|Fuels|Header 0|CleanTipResults|HR'，值: 10776333.422366736，}，{ Name：'FuelSide|Fuels|Header 0|CleanTipResults|HR_不确定性‘，值: 14383.420657232984，}，{ Name：'FuelSide|Fuels|Header 0|CleanTipResults|HR_MMBTUhr'，值: 36.77037592294784，}，{ Name：'FuelSide|CleanTipResults|HR'，值: 10776333.422366736，}，{名称：‘FuelSide|CleanTipResults|HR_不确定性’，值: 14383.420657232984，}

Answer 1

我将提供我的想法，因为这里已经有了一个高质量的答案。但请注意，在未来，StackOverflow是用来在您遇到困难时帮助您的，而不是为您编写代码。请展示你自己的努力，并解释你被困在哪里。

我从我之前的答案中窃取了助手函数。path接受一个节点名称数组和一个对象，并返回对象中该路径处的值，如果任何节点不存在，则返回undefined。例如，应用于{foo: {bar: {baz: 42}, qux: 99}, corge: -1}的path (['foo', 'bar', 'baz'])会产生42。

getPaths是一个生成器函数，它为您提供指向对象叶节点的路径。因此，getPaths ({foo: {bar: {baz: 42}, qux: 99}, corge: -1})生成["foo", "bar", "baz"]，然后是["foo", "qux"]和["corge"]。

定制的transform函数遍历Name/Value对的数组，如果Value是字符串，则返回它们，否则使用getPaths将值转换为Condensed|Path|Names /值对的数组。使用flatMap将这些连接到单个列表中。

​

const path = (ps = [], obj = {}) =>
  ps .reduce ((o, p) => (o || {}) [p], obj)

function * getPaths(o, p = []) {
  if (Object(o) !== o || Object .keys (o) .length == 0) yield p 
  if (Object(o) === o)
    for (let k of Object .keys (o))
      yield * getPaths (o[k], [...p, Number.isInteger (Number (k)) ? Number (k) : k])
}

const transform = (orig) => 
  orig .flatMap (({Name, Value}) => 
    typeof Value == 'string' 
      ? {Name, Value}
      : [... getPaths (Value)] .map (
          route => ({Name: Name + '|' + route .join ('|'), Value: path (route, Value)})
        )
  )

const orig = [{Name: "ZoneName", Value: "Box A"}, {Name: "AirSide", Value: {JZCleanTipFlowResults: {LeakageAirFlowRate: 2.0519336991674058, LeakageAirFlowRate_Uncertainty: .05755421849942835, LeakageAirFlowRate_lbmhr: 16285.188088630204, LeakageAirFlowRate_lbmhr_Uncertainty: 456.779511900225}, UsedAmbientTemperatureForCombustion: true, SubStoichWarning: false}}, {Name: "FuelSide", Value: {Fuels: {"Header 0": {CleanTipResults: {HR: 10776333.422366736, HR_Uncertainty: 14383.420657232984, HR_MMBTUhr: 36.77037592294784}}}, CleanTipResults: {HR: 10776333.422366736, HR_Uncertainty: 14383.420657232984}}}];

console .log (transform (orig))

.as-console-wrapper {min-height: 100% !important; top: 0}

Answer 2

如果你只是在寻找一个复制/粘贴的答案，我不会费心提供太多的解释。但我不介意完成拼图和分享我的作品-

1. 如果输入是对象，则
2. 将其“展平”。
3. 否则，输入不是对象。返回“扁平”结果。

​

const transform = (o = {}, path = []) =>
  Object(o) === o   // 1
    ? Object        // 2
        .entries(o)
        .flatMap(([ k, v ]) => transform(v, [...path, k]))
    : [ { path: path.join("|"), value: o } ] // 3

const data =
  [{Name:'ZoneName',Value:'Box A'},{Name:'AirSide',Value:{JZCleanTipFlowResults:{LeakageAirFlowRate:2.0519336991674058,LeakageAirFlowRate_Uncertainty:0.05755421849942835,LeakageAirFlowRate_lbmhr:16285.188088630204,LeakageAirFlowRate_lbmhr_Uncertainty:456.779511900225},UsedAmbientTemperatureForCombustion:true,SubStoichWarning:false}},{Name:'FuelSide',Value:{Fuels:{'Header 0':{CleanTipResults:{HR:10776333.422366736,HR_Uncertainty:14383.420657232984,HR_MMBTUhr:36.77037592294784}}},CleanTipResults:{HR:10776333.422366736,HR_Uncertainty:14383.420657232984}}}]

const result =
  transform(data)

console.log(JSON.stringify(result, null, 2))

​
