处理对象并以有效方式存储

问题描述

我收到一个具有键和值的基本模式的对象（ Object1 ），然后我想在MongoDB中处理并保存输出，使其包含数组对象。本质上是动态的“位置”和“地址”。

请建议我采取任何有效的方法。

const Object1 = { 
                        date:'07-Sep-2020',Address_1_Ftime: 2,Address_1_Rtime: 0,Address_1_Stime: 49,Address_2_Ftime: 12,Address_2_Rtime: 40,Address_2_Stime: 9

                        Location1Name:'SAV2',Location1Val:30,Location2Name:'LT232',Location2Val:130,}


const Output = 
{
    date : '07-Sep-2020',Address:
    [
        {
            name:'Address_1',Ftime:2,Rtime:0,Stime:49
        },{
            name:'Address_2',Ftime:12,Rtime:40,Stime:9
        }
    ],Locations:[
    {
        text:Location1,name:SAV2,value:30
    },{
        text:Location1,name:LT232,value:130
    }
    ]
}

解决方法

尝试完成后，请检查以下代码。 并且让我知道您是否不关注那里的内容。

const Object1 = { 
  date:'07-Sep-2020',Address_1_Ftime: 2,Address_1_Rtime: 0,Address_1_Stime: 49,Address_2_Ftime: 12,Address_2_Rtime: 40,Address_2_Stime: 9,Location1Name:'SAV2',Location1Val:30,Location2Name:'LT232',Location2Val:130,};

// Initialize the output
const Output = {
  Address: {},Locations: {}
};

Object.keys(Object1).forEach(key => {
  const value = Object1[key];
  if (key === 'date') {
    Output.date = value;
  } else if (key.startsWith('Address')) {
    const addressName = key.substr(0,key.length - 6);
    const addressFieldKey = key.substr(key.length - 5);
    Output.Address[addressName] = Output.Address[addressName] || {};
    Output.Address[addressName][addressFieldKey] = value;
  } else if (key.startsWith('Location')) {
    const fieldKeyLength = key.endsWith('Name') ? 4 : 3;
    const locationName = key.substr(0,key.length - fieldKeyLength);
    const locationFieldKey = key.substr(key.length - fieldKeyLength);
    Output.Locations[locationName] = Output.Locations[locationName] || {};
    Output.Locations[locationName][locationFieldKey] = value;
  }
});

// At this point,Address and Locations of Output are still objects not array. So you need the following change.

Output.Address = Object.keys(Output.Address).map(key => ({
  name: key,...Output.Address[key]
}));

Output.Locations = Object.keys(Output.Locations).map(key => ({
  text: key,name: Output.Locations[key].Name,value: Output.Locations[key].Val
}));

console.log(Output);
