Question

尝试从基于rejectMessage数组中的resolveCode的数组中删除元素，我觉得使用ES6或lodash可以更好。

有人可以帮我使用这种方法吗？

数据

const data = [
  {
        "drugName": "Metformin",
        "mailPrice": {
            "copayEmployer": "N/A",
            "totalQuantity": "90.0",
            "rejectMessage": [{
                "settlementCode": "99",
                "settlementDesc": "Not Covered: Call us - System could not process your request. Call us at the toll-free number on your benefit ID card.||Sin cobertura: Llámenos - El sistema no pudo procesar su solicitud. Llame al número gratuito que figura en su tarjeta de identificación de beneficios."
            }]
        },
        "retailPrice": {
            "copayEmployer": "N/A",
            "totalQuantity": "30.0"
        }
    },
    {
        "drugName": "CALCIUM",
        "mailPrice": {
            "copayEmployer": "N/A",
            "totalQuantity": "90.0"
        },
        "retailPrice": {
            "copayEmployer": "N/A",
            "totalQuantity": "30.0"
        }
    }
]

transform.js

    function transformPrice(drugPrice) {

          if (drugPrice.retailPrice.rejectMessage.length || drugPrice.mailPrice.rejectMessage.length ){
            const retailRejecrMsg = drugPrice.retailPrice.rejectMessage;
            const mailRejectMsg = drugPrice.mailPrice.rejectMessage;
            const retailErr = isErrorPresent(retailRejecrMsg);
            const mailErr =  isErrorPresent(mailRejectMsg);
          }

          if(retailErr){
            delete drugPrice.retailPrice;
          }

          if( mailErr){
            delete drugPrice.mailPrice;
          }

          return drugPrice;
        }

        function isErrorPresent (price) {
          const isError = function (element) {
            const bRet = checkErrorCodes(element);
            return (element.hasOwnProperty('settlementCodes') && bRet)
          }

          return price.some(isError);
        }

        function checkErrorCodes(el){
          let bRet = false;
          const errorCodes = [
            10015,
            2356,
            225,
            224,
              99
          ] 
          for (const err of errorCodes){

            if (err === ele.settlementCode){

              bRet = true;
            }
          }
           return bRet;
        }

transformPrice(data);

预期结果

[{
    "drugName": "Metformin",
    "retailPrice": {
      "copayEmployer": "N/A",
      "totalQuantity": "30.0"
    }
  },
  {
    "drugName": "CALCIUM",
    "mailPrice": {
      "copayEmployer": "N/A",
      "totalQuantity": "90.0"
    },
    "retailPrice": {
      "copayEmployer": "N/A",
      "totalQuantity": "30.0"
    }
  }
]

您的意思是这样吗？

import _ from 'lodash';

const drugPrice = data.map(item => {
  const errorCodes = [10015, 2356, 225, 224, 99];
  const f = ["mailPrice.rejectMessage", "retailPrice.rejectMessage"];

  f.forEach(path => {
    const rejectMsg = _.get(item, path);

    if (rejectMsg) {
      const y = path.split(".").shift();
      const hasCodeOrWrong = rejectMsg.find(i => {
        return !!~errorCodes.indexOf(+i.settlementCode)
            || !!~i.settlementDesc.indexOf(':');
      });

      hasCodeOrWrong && delete item[y];
    }
  });

  return item;
});

有没有办法在es6过滤器或lodash中获得相同的结果？
