Question

因此，下面注释掉的代码正在lodash中工作，只是想将其转换为es6以使其更简单，更清晰，所以它的抛出错误是未定义的。这里有什么帮助吗？

main.js

body {
  position: absolute;
  z-index: 0;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
  width: 100%;
  height: 100%;
  border: 0;
  margin: 0;
  padding: 0;
  min-width: 100px;
  min-height: 100vh;
  -ms-text-size-adjust: 100%;
  -webkit-text-size-adjust: 100%;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.map-overlay {
  flex-flow: row nowrap;
  justify-content: flex-start;
  width: 100vw;
  height: 30vh;
  bottom: 0;
  left: 0;
  margin: 0;
  overflow-x: scroll;
  overflow-y: hidden;
  -webkit-overflow-scrolling: touch;
  -ms-overflow-style: -ms-autohiding-scrollbar;
  display: flex;
  position: fixed;
  background-color: rgba(255, 150, 150, 0.3);
  font: 'Abel', 'Helvetica Neue', Arial, Helvetica, sans-serif;
  cursor: pointer;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
  color: #8e3433;
}

.scroll {
  overflow: auto;
}

.column {
  flex-direction: column;
}

.row,
.column,
.flex {
  display: flex;
  flex-wrap: wrap;
}

div {
  display: block;
}

html,
body,
#q-app {
  width: 100%;
  direction: ltr;
}

.mycard {
  flex: 1 1 auto;
  min-width: 47vw;
  margin: 3px 0 9px 2vw;
  justify-content: flex-end;
  border-radius: 2px;
  display: flex;
}

findErr方法

预期产量

由于const rejectMessagerrors = [45,67,87]; const drug = [{ "isBrand": true, "drugName": "Lipitor", "specialtyPrice": {} }, { "isBrand": false, "drugName": "Atorvastatin Calcium", "drugStrength": "80mg", "drugForm": "Tablet", "mailPrice": { "totalQuantity": 90, "rejectMessage": [{ "settlementCode": "45", "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": {} } ]; function priceFilterHandler(drug) { // const pricePath = ['mailPrice.rejectMessage', 'retailPrice.rejectMessage']; // // _.forEach(pricePath, function (path) { // const rejectMsg = _.get(drug, path); // const hasCode = rejectMsg && rejectMsg.find(i => !!~rejectMessagerrors.indexOf(+i.settlementCode)); // hasCode && delete drug[path.split('.').shift()]; // }); const retailHasCode = findErrCode(item.retailPrice.rejectMessage); const mailHasCode = findErrCode(item.mailPrice.rejectMessage); if (retailHasCode) { delete item.retailPrice; } if (mailHasCode) { delete item.mailPrice; } return item; } const filteredPrices = _.map(drug, priceFilterHandler);中包含了结清代码45，因此价格应与let findErrCode = data => { data.some(i => rejectMessagerrors.includes(+i.settlementCode)); }列表元素相匹配

mailPrice

Answer 1

这是您在代码中遇到的一些问题

findError函数没有返回值
某些元素在尝试访问mailPrice or retailPrice的地方没有item.mailPrice.rejetcMessage

const rejectMessagerrors = [45, 67, 87];
const drug = [{"isBrand": true,"drugName": "Lipitor","specialtyPrice": {}},{"isBrand": false,"drugName": "Atorvastatin Calcium","drugStrength": "80mg","drugForm": "Tablet","mailPrice": {"totalQuantity": 90,"rejectMessage": [{"settlementCode": "45","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": {}}];

let findErrCode = data => data && data.some(i => rejectMessagerrors.includes(+i.settlementCode));

let op = drug.map(item=> {
const retailHasCode = findErrCode(item.retailPrice && item.retailPrice.rejectMessage);
  const mailHasCode = findErrCode(item.mailPrice && item.mailPrice.rejectMessage);

  if (retailHasCode) {
    delete item.retailPrice;
  }

  if (mailHasCode) {
    delete item.mailPrice;
  }

  return item;
})

console.log(op)

尝试将lodash代码转换为es6方法；它抛出错误？
