Question

如果对象rejectMessage包含我在checkErrorCodes方法中指定的代码，则尝试返回布尔值。如果定居代码与其未返回的布尔值匹配，则它应该返回true，它正在重新调整整个isError函数。有什么想法或更好的方法可以做到这一点吗？

transformPrice.js

function transformPrice(oldDrugPrice) {
      let drugPrice =  {
            "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"
            }
        },

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

      }

      return drugPrice;
    }

isErrorPresent方法

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

  return isError;
}

checkErrorCodes方法

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

  for (const err of errorCodes){

    if (err === el.settlementCode){

      bRet = true;
    }
  }
   return bRet;
}

Answer 1

如何调用is错误方法

const mailErr =isErrorPresent(mailPriceMsg).call();

或更改isErrorPresent方法

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

Answer 2

在isErrorPresent函数中，您永远不会调用isError函数。要调用它，您应该：

return isError(price)

这将调用带有参数price的函数所以在您的示例中，它看起来像：

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

  return isError(price);
}

Answer 3

您在这里所做的是创建一个返回另一个函数的函数：

return isError

仔细观察，您会发现isErrorPresent(price)(element)实际上是在返回对函数的引用，而不是在调用函数后返回结果。

您可以像这样调用两个函数：function isErrorPresent (price, element) { const bRet = checkErrorCodes(element); return (element.hasOwnProperty('settlementCode') && bRet); }

或这样定义函数：

isErrorPresent(price, element)

然后将其命名为{{1}}。

Answer 4

您可以使用类似的东西：

function isErrorPresent (obj) {

  if(checkErrorCodes(obj) && obj.hasOwnProperty('settlementCode')){ //error code checked
    return obj; //return obj
  }
  return false; //no error found

}

function checkErrorCodes(el){
  const errorCodes = [
    10015,
    2356,
    225,
    224,
      99
  ]
  return errorCodes.includes(el.settlementCode);
}

这就是我要解决的方法。希望这会有所帮助。

Answer 5

我已经运行了您的代码，发现了几个问题：

isErrorPresent方法返回isError方法不是值
在transformPrice方法中，您遇到一些问题，例如：
- If语句前缺少分号
- rejectMessage是您应该通过索引访问的数组。
- 您没有为retailRejecrMsg和mailPriceMsg检查null

我也不知道检查错误后想要什么，所以我将值添加到drugPrice.mailErr和drugPrice.retailErr。

我已解决，希望对您有所帮助。

function transformPrice() {
      let drugPrice =  {
            "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"
            }
        };

      if (drugPrice.retailPrice.rejectMessage || drugPrice.mailPrice.rejectMessage.length ){
        const retailRejecrMsg = drugPrice.retailPrice.rejectMessage ? drugPrice.retailPrice.rejectMessage[0]: null;
        const mailPriceMsg = drugPrice.mailPrice.rejectMessage ? drugPrice.mailPrice.rejectMessage[0]: null;
        drugPrice.retailErr = !retailRejecrMsg ? true : isErrorPresent(retailRejecrMsg);
        drugPrice.mailErr = !mailPriceMsg ? true : isErrorPresent(mailPriceMsg);
      }

      return drugPrice;
}

function isErrorPresent (price) {
    const bRet = checkErrorCodes(price);
    return (price.hasOwnProperty('settlementCode') && bRet)
}

function checkErrorCodes(el){
  let bRet = false;
  const errorCodes = [
    10015,
    2356,
    225,
    224,
    99
  ]

  for (const err of errorCodes){
    if (err === el.settlementCode){
      bRet = true;
    }
  }
   return bRet;
}
console.log(transformPrice())
