如何在JS中删除属性并映射新对象？

Question

想要删除具有匹配errorCode的属性并在完成所有筛选后转换新对象，我不会低于预期的响应率吗？下面的代码是什么问题？

如果解决方案代码与drugPriceErrors匹配，则findErrCode应该返回true。

main.js

const data = [{
            "isBrand": true,
            "drugName": "Lipitor",
            "mailPrice": {
                "totalQuantity": 90,
                "rejectMessage": [{
                    "settlementCode": "99",
                    "settlementDesc": "Sorry, the system is temporarily:Lo sentimos,Intente(Código de error 85)"
                }]
            },
            "retailPrice": {
                "totalQuantity": 30,
                "rejectMessage": [{
                    "settlementCode": "85",
                    "settlementDesc": "Sorry, the system is temporarily:Lo sentimos,Intente(Código de error 85)"
                }]
            },
            "specialtyPrice": {}
        },
        {
            "isBrand": false,
            "drugName": "Atorvastatin Calcium",
            "drugStrength": "80mg",
            "drugForm": "Tablet",
            "mailPrice": {
                "totalQuantity": 90,
                "rejectMessage": [{
                    "settlementCode": "99",
                    "settlementDesc": "Sorry, the system is temporarily:Lo sentimos,Intente(Código de error 85)"
                }]
            },
            "retailPrice": {
                "totalQuantity": 30,
                "rejectMessage": [{
                    "settlementCode": "99",
                    "settlementDesc": "Sorry, the system is temporarily:Lo sentimos,Intente(Código de error 85)"
                }]
            },
            "specialtyPrice": {}
        }
    ];

const drugPricesErrors = [99,45,89];

function filterDrugs (data) { 
  const response = [];
const _drugPrice = data.map(item => {
        const retailHasCode = findErrCode(item.retailPrice.rejectMessage);
        const mailHasCode = findErrCode (item.mailPrice.rejectMessage);

        if(retailHasCode) {
            delete item.retailPrice;
        }

        if(mailHasCode) {
            delete item.mailPrice;
        }

  return item;

    });

    _.forEach(_drugPrice, function(drug) {
        if(drug.retailPrice !== undefined || drug.mailPrice !== undefined){
            response.push(drug);
        }
    });

  return response;
}

function findErrCode(data) {
    const filterMessage = data.filter( message => drugPriceErrors.includes(item.settlementCode));
    return filterMessage;
}

            "drugName": "Lipitor",
            "retailPrice": {
                "totalQuantity": 30,
                "rejectMessage": [{
                    "settlementCode": "85",
                    "settlementDesc": "Sorry, the system is temporarily:Lo sentimos,Intente(Código de error 85)"
                }]
            },
            "specialtyPrice": {}
        }
    ]

将您的findErrCode更新为以下内容：

let findErrCode = data => 
  data.some(i => drugPriceErrors.includes(Number(i.settlementCode)))

关键是使用Number转换您的settlementCode以便Array.some工作。 也请使用Array.some因为您只关心结果是true还是false（布尔值）。 Array.filter实际上会返回记录等。
