原始json数据：

预期的 json 数据：

{ 
  "UniversalOne": "",
  "CommonOne": ""
  "Implementations":    [
    {

            ]

      },

                },
                {
                  "Orientation": "Female",
                  "Name": IJKL        
                }
              ],
        "State": [
                {          
                  "Address": "XYZ Street",
                  "ZipCode": "US"

  "ReadingHabits": {    
    "Type": "Fast"    
  },
  "FitnessHabits": {   
  },
  "UniversalThree": "",
  "CommonThree": ""

}

程序：

//Original JSON data in question.
var Implementations = {
  "UniversalOne": "",
  "CommonOne": ""
  "Implementations": [
    {      
      "Male": {
        "Gender": "Male"              
      },
      "Female": {
        "Gender": "Female"       
      },

      "Country": [
        {
          "Orientation": "Male",          
          "Name": ABCD
        },
        {
          "Orientation": "Female",
          "Name": EFGH
        },
        {
          "Orientation": "Female",
          "Name": IJKL        
        }
      ],
      "State": [
        {          
          "Address": "XYZ Street",
          "ZipCode": "US"
        }
      ]
    }
  ],
  "PersonalityTraits": [
    {
      "Type": "Positive"
    },
    {      
      "Type": "Negative" 
    }  
  ],
  "UniversalTwo": "",  
  "CommonTwo": "",  
  "EatingHabits": {    
    "Type": "Excessive"
  },
  "ReadingHabits": {    
    "Type": "Fast"    
  },
  "FitnessHabits": {   
  },
  "UniversalThree": "",
  "CommonThree": ""
}

// Program that make the conversion
var finalResult = [];
for (var i=0; i<Implementations.Implementations.length; i++) {
  var currentImplementation = Implementations.Implementations[i];
  var targetObj = {
    "Male": {
      "Gender": "Male",
      "Country": [],
      "State": currentImplementation.State
    },
    "Female": {
      "Gender": "Female",
      "Country": [],
      "State": currentImplementation.State
    }
  };
  for (var j=0; j<currentImplementation.Country.length; j++) {
    var currentCountry = currentImplementation.Country[j];
    if (currentCountry.Orientation === 'Male') {
      targetObj.Male.Country.push(currentCountry);
    } else if (currentCountry.Orientation === 'Female') {
      targetObj.Female.Country.push(currentCountry);
    }
  }
  finalResult.push(targetObj);
}

console.log(JSON.stringify(finalResult));

如何在当前程序的 Implementations 对象之外添加诸如 Personality Traits、Eating Habits、Reading Habits、Fitness Habits 等对象以及 Universal 和 common 等属性？

【问题讨论】：

向 JavaScript 对象添加属性是一件基本的事情。到目前为止，您尝试过什么？
for (var k=0; j

【解决方案1】：

如果我没有正确回答您的问题，我认为您的代码已经为您提供了预期的 JSON for Implementations 属性。

[
  {
    "Male": {
      "Gender": "Male",
      "Country": [
        {
          "Orientation": "Male",
          "Name": "ABCD"
        }
      ],
      "State": [
        {
          "Address": "XYZ Street",
          "ZipCode": "US"
        }
      ]
    },
    "Female": {
      "Gender": "Female",
      "Country": [
        {
          "Orientation": "Female",
          "Name": "EFGH"
        },
        {
          "Orientation": "Female",
          "Name": "IJKL"
        }
      ],
      "State": [
        {
          "Address": "XYZ Street",
          "ZipCode": "US"
        }
      ]
    }
  }
]

因此，如果您询问如何添加其余属性以实现您预期的 JSON，您可以这样做：

Implementations.Implementations = finalResult;

这会将原始 JSON 实现属性替换为您创建的属性。

所以说：

var Implementations = {
  "UniversalOne": "",
  "CommonOne": ""
  "Implementations": [
    {      
      "Male": {
        "Gender": "Male"              
      },
      "Female": {
        "Gender": "Female"       
      },

      "Country": [
        {
          "Orientation": "Male",          
          "Name": ABCD
        },
        {
          "Orientation": "Female",
          "Name": EFGH
        },
        {
          "Orientation": "Female",
          "Name": IJKL        
        }
      ],
      "State": [
        {          
          "Address": "XYZ Street",
          "ZipCode": "US"
        }
      ]
    }
  ],
  "PersonalityTraits": [
    {
      "Type": "Positive"
    },
    {      
      "Type": "Negative" 
    }  
  ],
  "UniversalTwo": "",  
  "CommonTwo": "",  
  "EatingHabits": {    
    "Type": "Excessive"
  },
  "ReadingHabits": {    
    "Type": "Fast"    
  },
  "FitnessHabits": {   
  },
  "UniversalThree": "",
  "CommonThree": ""
}

如果你执行 Implementations.Implementations = filteredResult; 实现将变为：

{
  "UniversalOne": "",
  "CommonOne": ""
  "Implementations": [
  {
    "Male": {
      "Gender": "Male",
      "Country": [
        {
          "Orientation": "Male",
          "Name": "ABCD"
        }
      ],
      "State": [
        {
          "Address": "XYZ Street",
          "ZipCode": "US"
        }
      ]
    },
    "Female": {
      "Gender": "Female",
      "Country": [
        {
          "Orientation": "Female",
          "Name": "EFGH"
        },
        {
          "Orientation": "Female",
          "Name": "IJKL"
        }
      ],
      "State": [
        {
          "Address": "XYZ Street",
          "ZipCode": "US"
        }
      ]
    }
  }
],
  "PersonalityTraits": [
    {
      "Type": "Positive"
    },
    {      
      "Type": "Negative" 
    }  
  ],
  "UniversalTwo": "",  
  "CommonTwo": "",  
  "EatingHabits": {    
    "Type": "Excessive"
  },
  "ReadingHabits": {    
    "Type": "Fast"    
  },
  "FitnessHabits": {   
  },
  "UniversalThree": "",
  "CommonThree": ""
}

否则，请多解释一下您想要实现的目标。

【讨论】：

该程序仅处理实现属性。如果您在我的预期响应中向下滚动，我如何在实施后添加人格特征、阅读习惯、饮食习惯、健身习惯？为了简短起见，我希望通过调整从有问题的预期 json 响应中获得准确的响应当前程序。目前，当我运行程序时，我看不到任何在人格特征到底部之后的任何内容。
originalJSON 是一个模块吗？我收到未定义错误。
能否在评论中添加sn-p？我完全不明白如何实施您的回复。我是否将整个 Json 添加到另一个变量中？
@Eva 我将制作一个更小的对象，因为我无法复制和粘贴您的 JSON 对象。 var x = {UniversalOne：“”，CommonOne：“”，实现：[]}；如果你这样做 x.Implementations = filteredResult;根据原始 x，它仍然具有 UniversalOne、CommonOne，但 x.Implementations 将替换为过滤结果。希望这是有道理的
知道了，现在说得通了——非常感谢！尝试上述方法后，我遇到了 for (var i=0; i
