Javascript discord.js 排行榜

问题描述

所以现在我正在尝试制作 XP 排行榜，但我很困。我能够将它放在将 XP 放置的位置，但我无法弄清楚如何使用 XP 来按顺序传递其他信息，例如用户名等。老实说，我可能正朝着完全错误的方向前进。我现在的代码是：

        let obj = {
            '737903775691309127': {
                authorid: '737903775691309127',username: 'Vibe Development',serverID: '789259215868395552',xp: 391,level: 1,message: 50,avatarURL: 'https://cdn.discordapp.com/avatars/737903775691309127/91fa0efafb801dcbea4a669a67c6602e.webp'

                authorid: '632293976661164052',username: 'Paisley Park',message: 2,avatarURL: 'https://cdn.discordapp.com/avatars/632293976661164052/55146c900a44874dcb75d13df16ceb68.webp'
            },'368362411591204865': {
                authorid: '368362411591204865',username: 'Melijn',avatarURL: 'https://cdn.discordapp.com/avatars/368362411591204865/9326b331e0e42f185318bb305fdaa950.webp'
            },'716293342740348948': {
                authorid: '716293342740348948',username: 'Pokedi',xp: 32,avatarURL: 'https://cdn.discordapp.com/avatars/716293342740348948/2ef9cd6588c333a3299f694a23e4fa4d.webp'
            }
        };

        const res = await Object.values(obj);
        var levels = [];
        for (let index = 0; index < res.length; index++) {

            levels.push(res[index].xp);
        }
        levels.sort((a,b) => b - a);
        console.log(levels)
       // [ 753,391,32,29,14,13,8,3 ]

对象是：

let obj = {
            'userid': {
                authorid: 'userid',username: 'username',serverID: 'server id',avatarURL: 'users avatar'
            },

我也想得到的是返回的数组看起来像

            [
                {
                    authorid: '455139054464270345',avatarURL: 'https://cdn.discordapp.com/avatars/455139054464270345/a_9ab406e25e688594f8316909f0c470b5.gif'
                },{
                    authorid: '737903775691309127',avatarURL: 'https://cdn.discordapp.com/avatars/737903775691309127/91fa0efafb801dcbea4a669a67c6602e.webp'
                },... and so on 
            ]

希望这一切都有意义。谢谢！

解决方法

要获取按属性排序的对象数组（在本例中为 xp），而不仅仅是属性本身，您应该直接在 xp 属性上使用 Array.sort，而无需先创建 levels 数组。类似的东西：

const sortedObjects = 
    Object.values(obj) // get an array of the objects themselves
    .sort((a,b) =>
        b.xp - a.xp // sort by xp from greatest to least
    );

或者只是：

const sortedObjects = Object.values(obj).sort((a,b) => b.xp - a.xp)

将返回按其 xp 属性排序的对象数组。
