Question

我正在尝试根据字符串rank在数据集中的位置对它们进行排序。我尝试将indexOf与排序一起使用只能获得有限的成功。我确实找到了另一篇类似的文章，尽管它与我的问题无关（对于任何重复的记者）。

数据集：

[
    {
    "_id": {
        "$oid": "5b535f6eddfad00564b103db"
    },
    "notes": [
        "Very attractive"
    ],
    "warns": [],
    "username": "Saddy",
    "avatar": "https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/3c/3ce7fd0c1a5225790d67d90d4f1e60d2d29d2037_full.jpg",

    "rank": "Administrator",
    "__v": 0
},
{
    "_id": {
        "$oid": "5b54d085ed4855275f4cea63"
    },
    "notes": [],

    "enactedBans": 0,
    "currentTickets": 0,
    "totalTickets": 0,
    "rank": "Moderator",
    "__v": 0
}
]

尝试失败：

console.log(arr.sort(function(a){ 
    return ["Owner", "Administrator", "Moderator"].indexOf(a.rank)
}))


arr.sort(function(a,b){ 
let sort = Object.assign({}, a, b);
    return["Owner", "Administrator", "Moderator"].indexOf(sort.rank)
})

都只是用我的替换所有数据。谢谢您的协助

您需要在提供给a的参数中同时使用b和sort-通过["Owner", "Administrator", "Moderator"]数组中它们的索引差异进行比较。

const input=[{"_id":{"$oid":"5b535f6eddfad00564b103db"},"notes":["Very attractive"],"warns":[],"username":"Saddy","avatar":"https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/3c/3ce7fd0c1a5225790d67d90d4f1e60d2d29d2037_full.jpg","id":"76561198151478478","dateHired":{"$date":"2018-07-21T16:29:34.563Z"},"profile":"https://steamcommunity.com/id/dpitt/","enactedBans":0,"currentTickets":0,"totalTickets":0,"rank":"Administrator","__v":0},{"_id":{"$oid":"5b54d085ed4855275f4cea63"},"notes":[],"warns":[],"username":"meme master nick","avatar":"https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/f6/f61f5d62b79b22c9183c049521a4c587ab9334cd_full.jpg","id":"76561198353773365","dateHired":{"$date":"2018-07-22T18:44:21.814Z"},"profile":"https://steamcommunity.com/profiles/76561198353773365/","enactedBans":0,"currentTickets":0,"totalTickets":0,"rank":"Owner","__v":0},{"_id":{"$oid":"5b567169e7179a32d9cc2abe"},"notes":[],"warns":[],"username":"DarkGamer2k16","avatar":"https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/3d/3dd1f81fc4556ae984ebe2312e1b9fc4ba54b5ea_full.jpg","id":"76561194018842253","dateHired":{"$date":"2018-07-21T16:29:34.563Z"},"profile":"https://steamcommunity.com/id/DarkGamer2k16/","enactedBans":0,"currentTickets":0,"totalTickets":0,"rank":"Moderator","__v":0}]

const ranks = ["Owner", "Administrator", "Moderator"];
input.sort((a, b) => ranks.indexOf(a.rank) - ranks.indexOf(b.rank));
console.log(input);

根据数组中字符串值的索引对对象数组进行排序
