如何从JavaScript的boxes与items数组生成指定结构的final数组

原始数组 #

boxes数组 #

const boxes=[
    {
        "trolleyNo": "345A",
        "trolleyItems": [
            {
                "key": "02f2c8e0-cd40-11ed-8563-092a964acecc",
                "name": "Bar Cart - Liquor, Liqueur",
                "value": "Bar Cart - Liquor, Liqueur",
                "label": "Bar Cart - Liquor, Liqueur"
            },
            {
                "key": "02f2c8e0-cd40-11ed-8563-092a964acecc",
                "name": "Bar Cart - Beer & Wine",
                "value": "Bar Cart - Beer & Wine",
                "label": "Bar Cart - Beer & Wine"
            },
            {
                "key": "02f2c8e0-cd40-11ed-8563-092a964acecc",
                "name": "Bread Basket & Tongs",
                "value": "Bread Basket & Tongs",
                "label": "Bread Basket & Tongs"
            },
            {

                "name": "Crew Store - Cookies, juices, etc",
                "value": "Crew Store - Cookies, juices, etc",
                "label": "Crew Store - Cookies, juices, etc"
            }
        ],
        "cartType": "fullCart",
        "index": "FC-093"
    },
    {
        "trolleyNo": "560S",
        "trolleyItems": [
            {
                "key": "02f2c8e0-cd40-11ed-8563-092a964acecc",
                "name": "Bar Cart - Beer & Wine",
                "value": "Bar Cart - Beer & Wine",
                "label": "Bar Cart - Beer & Wine"
            },
            {
                "key": "02f2c8e0-cd40-11ed-8563-092a964acecc",
                "name": "Bread Basket & Tongs",
                "value": "Bread Basket & Tongs",
                "label": "Bread Basket & Tongs"
            },
            {
                "key": "02f2c8e0-cd40-11ed-8563-092a964acecc",
                "name": "Crockery - Full Plates",
                "value": "Crockery - Full Plates",
                "label": "Crockery - Full Plates"
            }
        ],
        "cartType": "halfCart",
        "index": "FC-093"
    }
]

items数组 #

const items= [
    {
        "_id": "646d96f669cad73dc5d14a25",
        "name": "Bar Cart - Beer & Wine",
        "customerId": "02f2c8e0-cd40-11ed-8563-092a964acecc"
    },
    {
        "_id": "646d96f669cad73dc5d14a24",
        "name": "Bar Cart - Liquor, Liqueur",
        "customerId": "02f2c8e0-cd40-11ed-8563-092a964acecc"
    },
    {
        "_id": "646d96f669cad73dc5d14a2b",
        "name": "Bread Basket & Tongs",
        "customerId": "02f2c8e0-cd40-11ed-8563-092a964acecc"
    },
    {
        "_id": "646d96f669cad73dc5d14a2d",
        "name": "Crew Meals",
        "customerId": "02f2c8e0-cd40-11ed-8563-092a964acecc"
    },
    {
        "_id": "646d96f669cad73dc5d14a31",
        "name": "Crew Store - Cookies, juices, etc",
        "customerId": "02f2c8e0-cd40-11ed-8563-092a964acecc"
    },
    {
        "_id": "646d96f669cad73dc5d14a32",
        "name": "Crockery - Full Plates",
        "customerId": "02f2c8e0-cd40-11ed-8563-092a964acecc"
    }
]

目标数组结构 #

const final= [
    {
        "cartId": "full",
        "itemsCategory": [
            {
                "categoryId": "645bbe9141332374a05919d2"
            },
            {
                "categoryId": "645bbf960e37e37b5c18e37e"
            }
        ]
    },
    {
        "cartId": "half",
        "itemsCategory": [
            {
                "categoryId": "645bc57dd374a392f8226708"
            },
            {
                "categoryId": "645bc588d374a392f8226709"
            }
        ]
    }
]

转换规则 #

• cartId映射规则：将boxes数组中元素的cartType字段转换，"fullCart"转为"full"，"halfCart"转为"half"
• itemsCategory生成规则：遍历boxes中每个元素的trolleyItems数组，将每个元素的name与items数组中对象的name匹配，取匹配对象的_id作为categoryId的值，组成itemsCategory数组
