Lodash:在json中获取具有多个键值匹配的新数组 [英] Lodash:Getting new array with multiple key-value matches in json

问题描述

我已经将JSON变成了这样

I have nessted JSON look like this

[
    {arrivalTime: "10:30 PM"
     availableSeats: 23
    boardingPoints: [{id: "3882"
    location: "abc"
    time: "02:30PM"},{id: "3882"
    location: "xyz"
    time: "02:30PM"}]
    busType: "Scania Metrolink"
    operatorName:"sham"
    commPCT: 8
    departureTime: "1:15 PM"
    droppingPoints: [{id: "3882"
    location: "dex"
    time: "02:30PM"},{id: "3882"
    location: "afg"
    time: "02:30PM"}]
    },
    {arrivalTime: "10:30 PM"
     availableSeats: 23
    boardingPoints: [{id: "3882"
    location: "def"
    time: "02:30PM"},{id: "3882"
    location: "jkl"
    time: "02:30PM"}]
    busType: "Scania "
    operatorName:"manu"
    commPCT: 8
    departureTime: "1:15 PM"
    droppingPoints: [{id: "3882"
    location: "ccd"
    time: "02:30PM"},{id: "3882"
    location: "eef"
    time: "02:30PM"}]
    }
    ]

我要从中获取与这些key值匹配的新数组. 这是钥匙.

From this i want to get new array that matches the these key values. Here is the keys.

1.BoardingPoints.

1.BoardingPoints.

2.DroppingPoints.

2.DroppingPoints.

3.busType.

3.busType.

4.OperatorName.

4.OperatorName.

例如: 如果输入是这样

Eg: if the input like this

BoardingPoints=['abc']

DroppingPoints=['ccd','eef']

busType=['Scania Metrolink']，

OperatorName=['manu']

它应该返回这两行

{到达时间:晚上10:30"可容纳座位:23登机点:[{id: "3882"位置:" abc "时间:"02:30 PM"}，{id:"3882"位置: "xyz"时间:"02:30 PM"}] busType:" Scania Metrolink " operatorName:"sham" commPCT:8出发时间:"1:15 PM" droppingPoints:[{id:"3882"位置:"dex"时间:"02:30 PM"}，{id: "3882"位置:"afg"时间:"02:30 PM"}]}，

{arrivalTime: "10:30 PM" availableSeats: 23 boardingPoints: [{id: "3882" location: "abc" time: "02:30PM"},{id: "3882" location: "xyz" time: "02:30PM"}] busType: "Scania Metrolink" operatorName:"sham" commPCT: 8 departureTime: "1:15 PM" droppingPoints: [{id: "3882" location: "dex" time: "02:30PM"},{id: "3882" location: "afg" time: "02:30PM"}] },

{到达时间:晚上10:30" 可用座位:23登机点:[{id:"3882"位置:"def"时间: " 02:30 PM}，{id:" 3882位置:" jkl时间:" 02:30 PM}] busType: 斯堪尼亚"操作员姓名:"手册" commPCT:8出发时间:"1:15 PM" droppingPoints:[{id:"3882"位置:" ccd "时间:"02:30 PM"}，{id: "3882"位置:" ef "时间:"02:30 PM"}]}]

{arrivalTime: "10:30 PM" availableSeats: 23 boardingPoints: [{id: "3882" location: "def" time: "02:30PM"},{id: "3882" location: "jkl" time: "02:30PM"}] busType: "Scania " operatorName:"manu" commPCT: 8 departureTime: "1:15 PM" droppingPoints: [{id: "3882" location: "ccd" time: "02:30PM"},{id: "3882" location: "eef" time: "02:30PM"}] } ]

注意

每个输入都作为数组传递，因为我需要匹配键中的多个值.

Each input is passed as an array because i need to match multiple values in the keys.

推荐答案

从预期结果来看，您似乎正在寻找与4个变量中的任何一个都匹配的对象.这是与它们匹配的过滤器:

From the expected result, it looks like you are looking for the objects that match any of the 4 variables. Here is the filter that will match them:

var bpLocations = ['abc'];
var dpLocations = ['ccdll', 'eef'];
var busTypes = ['Scania Metrolink'];
var operatorNames = ['manu'];

var result = _.filter(inputArray, function(obj) {
    return _(obj.boardingPoints).map('location').intersection(bpLocations).value().length > 0
        || _(obj.droppingPoints).map('location').intersection(dpLocations).value().length > 0
        || _.includes(busTypes, obj.busType)
        || _.includes(operatorNames, obj.operatorName);
});
