如何将`control`数组中其余项的`currencyId`和`currencyCode`分叉

如何解决如何将`control`数组中其余项的`currencyId`和`currencyCode`分叉

我想将currencyId数组中其余项目的currencyCode和control分叉。 现在它给出的输出是：

[{
  channels: {ANDROID: 0,EMAIL: 0,INBox: 0,IOS: 0,SMS: 0,TELEGRAM: 0,currencyCode: "CFA",currencyId: 11},currency: {currencyCode: "CFA",currencyId: 11} 
}]

但是我想要输出：

[{
  channels: {ANDROID: 0,TELEGRAM: 0},currencyId: 11} 
}]

到目前为止，这是我的代码：

let chargesData = [
          {
            "SMS": 0,"IOS": 0,"ANDROID": 0,"EMAIL": 0,"currencyId": 11,"currencyCode": "CFA","TELEGRAM": 0,"INBox": 0
          },{
            "SMS": 10,"IOS": 10,"ANDROID": 10,"EMAIL": 10,"currencyId": 12,"currencyCode": "IND","TELEGRAM": 10,"INBox": 10
          }
        ]


    let control = [];
    let currency;
    for(let charges of chargesData) {
      let chargesChannels = Object.keys(charges)
      
      let currencyCode = chargesChannels.indexOf("currencyCode");
      let currencyId = chargesChannels.indexOf("currencyId");
      chargesChannels.splice(currencyCode,1);
      chargesChannels.splice(currencyId,1);
      
      currency = { currencyCode: charges.currencyCode,currencyId: charges.currencyId };
      control.push({
        channels: charges,currency: currency
      })
    }
    console.log(control);
  

该怎么做？

解决方法

您可以使用.map和destructuring进行此操作：

let chargesData = [
  {
    "SMS": 0,"IOS": 0,"ANDROID": 0,"EMAIL": 0,"currencyId": 11,"currencyCode": "CFA","TELEGRAM": 0,"INBOX": 0
  },{
    "SMS": 10,"IOS": 10,"ANDROID": 10,"EMAIL": 10,"currencyId": 12,"currencyCode": "IND","TELEGRAM": 10,"INBOX": 10
  }
]

const arr = chargesData.map(e => {
  const {currencyCode,currencyId,...channels} = e;
  return {
    channels: channels,currency: {currencyCode,currencyId}
  }
});

console.log(arr);

,

您可以使用in运算符遍历数组，然后遍历对象属性，然后根据需要分离出对象。

let chargesData = [
    {
    "SMS": 0,"INBOX": 0
    },"INBOX": 10
    }
];

const controls = [];
chargesData.forEach(charges=>{
    const control={
        channels:{},currency:{}
    }
    for (const key in charges) {
        if(["currencyCode","currencyId"].includes(key)){
            control.currency[key]=charges[key];
        }else{
            control.channels[key]=charges[key];
        }
    }
    controls.push(control);
});
console.log(controls);
