javascript - 将对象转换为对象的对象

Question

我有一个对象:

{
"Results": {
    "circle": 0.06879016757011414,
    "quad": {
        "exp": 0.8039023876190186,
        "actual": 0.19609761238098145
    },
    "square": 0.8266428709030151
 }
}

我想将其转换为:

{
"Results": {
    "circle": {
        "circle": 0.06879016757011414
    },
    "quad": {
        "exp": 0.8039023876190186,
        "actual": 0.19609761238098145
    },
    "square": {
        "square": 0.8266428709030151
    }
  }
}

尝试过这段代码:

var modData = {};
data = data.Results;
for (var key in data) {
  if (data.hasOwnProperty(key)) {
    modData[key] = data[key];
    for (var innerKey in data[key]) {
      modData[key] = data[key];
    }
  }
}
console.log("Modified is:", modData);

不幸的是，这仍然返回原始对象，我做错了什么？

jquery 解决方案也很好。

使用for .. in循环属性，如果任何属性不是对象，请将其替换为对象。像这样:

let x = {
  "Results": {
    "circle": 0.06879016757011414,
    "quad": {
      "exp": 0.8039023876190186,
      "actual": 0.19609761238098145
    },
    "square": 0.8266428709030151
  }
}
for (key in x.Results) {
  if (typeof x.Results[key] !== 'object')
    x.Results[key] = {
      [key]: x.Results[key]
    }
}

console.log(x);

如果您想保留原始对象，请执行以下操作:

let data = {
  "Results": {
    "circle": 0.06879016757011414,
    "quad": {
      "exp": 0.8039023876190186,
      "actual": 0.19609761238098145
    },
    "square": 0.8266428709030151
  }
}

data = data.Results;
modData = {};

for (key in data) {
  if (typeof data[key] !== 'object')
    modData[key] = { [key]: data[key] }
  else
    modData[key] = { [key]: data[key] }
}

console.log(modData);
