Question

我有2个对象，在这个mydata对象中我必须将国家/地区代码转换为国家/地区名称。国家名称我必须从国家/地区对象中选择它。

countries = [
  {
    "name": "Afghanistan",
    "code": "AF",
    "localizationLang": "en"
  },
  {
    "name": "Albania",
    "code": "AL",
    "localizationLang": "en"
  }
];

mydata = [{
    "orgCode": "ZC27693542",
    "orgName": "B - Sedex Conference Demo Purpose Only",
    "siteCode": null,
    "siteName": null,
    "countryCode": "AF",
    "state": null,
    "product": [],
    "productArea": [],
    "lastDateAudit": null,
    "saqPercentage": 0.0,
    "auditCode": null
},...
];

我希望输出对象应该是

[{
    "orgCode": "ZC27693542",
    "orgName": "B - Sedex Conference Demo Purpose Only",
    "siteCode": null,
    "siteName": null,
    "countryCode": "Afghanistan",
    "state": null,
    "product": [],
    "productArea": [],
    "lastDateAudit": null,
    "saqPercentage": 0.0,
    "auditCode": null
},...
]

我需要将国家/地区代码更改为国家/地区名称。

Answer 1

简单：）

mydata.map(x=>{
x.countryCode = countries.find(c=>c.code === x.countryCode).name; 
return x;
})

Answer 2

试试吧

var countries = [{
  "name": "Afghanistan",
  "code": "AF",
  "localizationLang": "en"
}, {
  "name": "Albania",
  "code": "AL",
  "localizationLang": "en"
}];

var mydata = [{
  "orgCode": "ZC27693542",
  "orgName": "B - Sedex Conference Demo Purpose Only",
  "siteCode": null,
  "siteName": null,
  "countryCode": "AF",
  "state": null,
  "product": [],
  "productArea": [],
  "lastDateAudit": null,
  "saqPercentage": 0.0,
  "auditCode": null
}, {
  "orgCode": "ZC27695039",
  "orgName": "Sonata-AB-Member",
  "siteCode": "ZS27695161",
  "siteName": "UEM group",
  "countryCode": "AL",
  "state": null,
  "product": [],
  "productArea": ["50203200", "50201700", "50202300"],
  "lastDateAudit": null,
  "saqPercentage": 13.0,
  "auditCode": null
}];

var newArr = mydata.map(function(value) {
  var country = countries.find(function(countrie) {
    return countrie.code == value.countryCode;
  });

  value.countryCode = country.name;
  return value;
});

console.log(newArr)
