問題描述

我使用 discord.js 制作了一個不和諧機器人，并嘗試執行幫助命令向用戶顯示所有可用命令.

i made a discord bot with discord.js and tried to do a help command to show the user all available commands.

示例命令:avatar.js

module.exports.run = async(bot, message, args) => {
    let msg = await message.channel.send("doing some magic ...");
    let target = message.mentions.users.first() || message.author;

    await message.channel.send({files: [
        {
            attachment: target.displayAvatarURL,
            name: "avatar.png"
        }
    ]});

    msg.delete();
}

module.exports.help = {
    name: "avatar",
    description: "show the avatar of a user",
    usage: "[@user]"
}

然后我嘗試發送帶有完整命令列表的消息，例如:

Then i tried to send a message with the complete list of the commands like:

• 命令 1
• 說明
• 用法
• 命令 2
• 說明
• 用法
• ...

help.js

const fs = require("fs");
const Discord = require("discord.js");

module.exports.run = async(bot, message, args, con) => {
    fs.readdir("./cmds/", (err, files) => {
        if(err) console.error(err);

        let jsfiles = files.filter(f => f.split(".").pop() === "js");
        if(jsfiles.length <= 0) {
            console.log("No commands to load!");
            return;
        }

        var namelist = "";
        var desclist = "";
        var usage = "";

        let result = jsfiles.forEach((f, i) => {
            let props = require(`./${f}`);
            namelist = props.help.name;
            desclist = props.help.description;
            usage = props.help.usage;
        });

        message.author.send(`**${namelist}** 
${desclist} 
${usage}`);
    });
}

module.exports.help = {
    name: "help",
    description: "show all commands",
    usage: ""
}

我的代碼有點工作，但它只發送第一個命令.

my code is kinda working but it only sends the first command.

我對 javascript 很陌生，我找不到解決方案.我試圖用谷歌搜索所有關于 foreach 地圖不和諧集合和東西的東西，但我找不到將結果組合在一起的例子.

Im pretty new to javascript and i can't find a solution to this. I tried to google everything on foreach maps discord collections and stuff but i cant find a example where the results get combined together.

如果有人可以幫助我或給我一個提示，我可以在哪里搜索類似的東西.會很棒.

If anybody can help me or give me a hint where i can search for something like this. Would be awesome.

推薦答案

你的代碼只發送一個命令的原因是你的代碼只調用 message.author.send('...' 一次.您成功地使用每個文件中的數據設置了變量 namelist、desclist 和 usage，但您的 .forEach(... 循環只是在移動到下一個文件時覆蓋所有數據.

The reason your code is only sending the one command is because your code only calls message.author.send('...' once. You successfully set the variables namelist, desclist, and usage with data from every file, but your .forEach(... loop just overwrites all of the data when it moves to the next files.

嘗試在 .forEach(... 循環的每次迭代中發送數據，如下所示:

Try to send data inside each iteration of the .forEach(... loop like this:

var namelist = "";
var desclist = "";
var usage = "";

let result = jsfiles.forEach((f, i) => {
    let props = require(`./${f}`);
    namelist = props.help.name;
    desclist = props.help.description;
    usage = props.help.usage;

    // send help text
    message.author.send(`**${namelist}** 
${desclist} 
${usage}`);
});
