Javascript 如何使用另一个json的顺序对json对象进行排序

我有一个公园列表（park_list），可以按距离和面积排序

我已成功使用以下代码按距离排序：

sortList(index){
  return function(a, b){
    return (a[index] === b[index] ? 0 : (a[index] < b[index] ? -1 : 1));
  }
}

我的区域列表如下所示：

[
    {
        "parkName" : "park4",
        "area_id" : "4"
    },
    {
        "parkName" : "park2",
        "area_id" : "2"
    },
    {
        "parkName" : "park1",
        "area_id" : "1"
    },
    {
        "parkName" : "park3",
        "area_id" : "3"
    },

]

{
    "cityId": "1",
    "areaId": "1",
    "areaName": "area1"
}, {
    "cityId": "1",
    "areaId": "2",
    "areaName": "area2"
}, {
    "cityId": "1",
    "areaId": "3",
    "areaName": "area3"
}, {
    "cityId": "1",
    "areaId": "4",
    "areaName": "area4"
}

{
    "cityId": "1",
    "areaId": "2",
    "areaName": "area2"
}, {
    "cityId": "1",
    "areaId": "4",
    "areaName": "area4"
}, {
    "cityId": "1",
    "areaId": "1",
    "areaName": "area1"
}, {
    "cityId": "1",
    "areaId": "3",
    "areaName": "area1"
}

[
    {
        "parkName" : "park2",
        "area_id" : "2"
    },
    {
        "parkName" : "park4",
        "area_id" : "4"
    },
    {
        "parkName" : "park1",
        "area_id" : "1"
    },
    {
        "parkName" : "park3",
        "area_id" : "3"
    },

]

我需要根据区域ID在区域列表中的顺序对公园列表进行排序

如果我的区域列表是这样的：

[
    {
        "parkName" : "park4",
        "area_id" : "4"
    },
    {
        "parkName" : "park2",
        "area_id" : "2"
    },
    {
        "parkName" : "park1",
        "area_id" : "1"
    },
    {
        "parkName" : "park3",
        "area_id" : "3"
    },

]

{
    "cityId": "1",
    "areaId": "1",
    "areaName": "area1"
}, {
    "cityId": "1",
    "areaId": "2",
    "areaName": "area2"
}, {
    "cityId": "1",
    "areaId": "3",
    "areaName": "area3"
}, {
    "cityId": "1",
    "areaId": "4",
    "areaName": "area4"
}

{
    "cityId": "1",
    "areaId": "2",
    "areaName": "area2"
}, {
    "cityId": "1",
    "areaId": "4",
    "areaName": "area4"
}, {
    "cityId": "1",
    "areaId": "1",
    "areaName": "area1"
}, {
    "cityId": "1",
    "areaId": "3",
    "areaName": "area1"
}

[
    {
        "parkName" : "park2",
        "area_id" : "2"
    },
    {
        "parkName" : "park4",
        "area_id" : "4"
    },
    {
        "parkName" : "park1",
        "area_id" : "1"
    },
    {
        "parkName" : "park3",
        "area_id" : "3"
    },

]

我的park_列表应按如下方式排序：

[
    {
        "parkName" : "park4",
        "area_id" : "4"
    },
    {
        "parkName" : "park2",
        "area_id" : "2"
    },
    {
        "parkName" : "park1",
        "area_id" : "1"
    },
    {
        "parkName" : "park3",
        "area_id" : "3"
    },

]

{
    "cityId": "1",
    "areaId": "1",
    "areaName": "area1"
}, {
    "cityId": "1",
    "areaId": "2",
    "areaName": "area2"
}, {
    "cityId": "1",
    "areaId": "3",
    "areaName": "area3"
}, {
    "cityId": "1",
    "areaId": "4",
    "areaName": "area4"
}

{
    "cityId": "1",
    "areaId": "2",
    "areaName": "area2"
}, {
    "cityId": "1",
    "areaId": "4",
    "areaName": "area4"
}, {
    "cityId": "1",
    "areaId": "1",
    "areaName": "area1"
}, {
    "cityId": "1",
    "areaId": "3",
    "areaName": "area1"
}

[
    {
        "parkName" : "park2",
        "area_id" : "2"
    },
    {
        "parkName" : "park4",
        "area_id" : "4"
    },
    {
        "parkName" : "park1",
        "area_id" : "1"
    },
    {
        "parkName" : "park3",
        "area_id" : "3"
    },

]

我真的很难过。我非常感谢任何帮助。

创建一个对象，使用方法保存每个

区域id的索引，然后使用该对象进行排序

const area_list_index = area_list.reduce((obj, { areaId }, i) => {
  obj[areaId] = i;
  return obj;
}, {})


park_list.sort((a, b) => area_list_index[a.area_id] - area_list_index[b.area_id])


let park_list=[{
“公园名称”：“公园4”，
“区域id”：“4”
},
{
“公园名称”：“公园2”，
“区域id”：“2”
},
{
“公园名称”：“公园1”，
“区域id”：“1”
},
{
“公园名称”：“公园3”，
“区域id”：“3”
},
]
让区域_列表=[{
“城市ID”：“1”，
“区域ID”：“2”，
“区域名称”：“区域2”
}, {
“城市ID”：“1”，
“区域ID”：“4”，
“区域名称”：“区域4”
}, {
“城市ID”：“1”，
“区域ID”：“1”，
“区域名称”：“区域1”
}, {
“城市ID”：“1”，
“区域ID”：“3”，
“区域名称”：“区域1”
}]
常量区域列表索引=区域列表。减少（（obj{
面积
}，i）=>{
obj[areaId]=i；
返回obj；
}, {})
park_list.sort（（a，b）=>区域列表索引[a.area_id]-区域列表索引[b.area_id]）
控制台日志（驻车列表）您可以为想要的顺序取一个，并按同一键的索引排序


var park_list=[{parkName:“park4”，area_id:“4”}，{parkName:“park2”，area_id:“2”}，{parkName:“park1”，area_id:“1”}，{parkName:“park3”，area_id:“3”}，
area_list=[{cityId:“1”，areaId:“2”，areaName:“2”}，{cityId:“1”，areaId:“4”，areaName:“area4”}，{cityId:“1”，areaId:“1”}，{cityId:“3”，areaName:“area1”}，
顺序=新地图（area_list.Map（{areaId}，i）=>[areaId，i]）；
park_list.sort（{area_id:a}，{area_id:b}）=>order.get（a）-order.get（b））；
控制台日志（驻车列表）
作为控制台包装{max height:100%！important；top:0；}
您想要什么样的解决方案（您添加了angular和ionic3作为标记）？。此外，您是否对列表结构或格式有任何控制权？
