如何使用 javascript

基于对象和数组列表获取对象数组

return基于两个条件的对象数组

1.if arrobj value is equal to obj valueid 和 cid value should not include only listcode 值

2.else 如果 arrobj value is equal to obj valueid 和 codevalue is equal to cid

其他return[]

应遵循上述条件，return arrayobject 使用 javscript

var listcode =["IN","FI", "FR"];
var arrobj =[
  {id:1, name: "jan", cid: "IN", value: "1234"},
  {id:2, name: "feb", cid: "SG", value: "2468"},
  {id:3, name: "mar", cid: "SP", value: "2468"},
  {id:4, name: "apri", cid: "FI", value: "2345"},
]
var obj={
  id:5, name: "zen", codevalue: "SP", valueid:"2468"
}

Expected Output
[
  {id:2, name: "feb", cid: "SG", value: "2468"},
  {id:3, name: "mar", cid: "SP", value: "2468"},
]

var listcode =["IN","FI","FR"];
var arrobj1 =[
  {id:1, name: "jan", cid: "IN", value: "1234"},
  {id:2, name: "feb", cid: "FI", value: "2468"},
  {id:3, name: "mar", cid: "IN", value: "2468"},
  {id:4, name: "apri", cid: "FI", value: "2345"},
]
var obj1={
  id:5, name: "zen", codevalue: "SP", valueid:"2468"
}
Expected Output
[]

const result = arrobj.filter(e => e.value === obj.valueid
      && listcode.includes(e.cid));
``

Answer 1

你做的都对，只是在!includes

前加一个否定

// data1
var listcode1 = ["IN","FI", "FR"];
var arrobj1 = [
  {id:1, name: "jan", cid: "IN", value: "1234"},
  {id:2, name: "feb", cid: "SG", value: "2468"},
  {id:3, name: "mar", cid: "SP", value: "2468"},
  {id:4, name: "apri", cid: "FI", value: "2345"},
]
var obj1 = { id:5, name: "zen", codevalue: "SP", valueid:"2468"}


// data2
var listcode2 = ["IN","FI","FR"];
var arrobj2 = [
  {id:1, name: "jan", cid: "IN", value: "1234"},
  {id:2, name: "feb", cid: "FI", value: "2468"},
  {id:3, name: "mar", cid: "IN", value: "2468"},
  {id:4, name: "apri", cid: "FI", value: "2345"},
]
var obj2 = { id:5, name: "zen", codevalue: "SP", valueid:"2468"}

function getNewArray(inputList, obj, listCodes) {
  const result = inputList.filter(x => x.value === obj.valueid && (!listCodes.includes(x.cid) || x.cid === obj.codevalue))
  return result;
}


console.log(getNewArray(arrobj1, obj1, listcode1))
console.log(getNewArray(arrobj2, obj2, listcode2))

Answer 2

可以通过过滤 arrobj.

来实现

var listcode =["IN","FI", "FR"];
var arrobj =[
  {id:1, name: "jan", cid: "IN", value: "1234"},
  {id:2, name: "feb", cid: "SG", value: "2468"},
  {id:3, name: "mar", cid: "SP", value: "2468"},
  {id:4, name: "apri", cid: "FI", value: "2345"},
]
var obj={
  id:5, name: "zen", codevalue: "SP", valueid:"2468"
}

const result = arrobj.filter((item) => {
  return item.value === obj.valueid &&
    (
      !listcode.includes(item.cid)
      || item.cid === obj.codevalue
    )
})
