循环显示帮助命令

Question

实际上，我尝试使用 discord.js 创建一个机器人并尝试执行帮助命令。

我不明白为什么我的循环会这样做（我知道这不是一个好方法）

let i = 0;
const embed = new RichEmbed();

if (args.length < 1) {
  embed.setColor('#5B4DCA');
  while (i < list_groups.length) {
    let x = 0;
    embed.setTitle(`${list_groups[i]}`)
    while (x < groups.length) {
      if (groups[x] === list_groups[i]) {
        embed.addField('test1', 'test2')
      }
      x++;
    }
    message.channel.send(embed)
    i++;
  }
}

“Modérations”应该显示一个命令，“level & rank”也是，“Outils”4 命令和“Sondage”也是

我认为你的解决方法不对。如果您将有超过 10 个组，机器人将发送垃圾邮件命令列表。如果args.length===0，则显示所有类别列表的第一种方法，如果 args !==0 您尝试查找此类别中的所有命令。要嵌入不和谐，您只能添加 18 个字段，因此如果您在 categroy 中有超过 18 个命令，您将收到 api 错误。所以你需要将命令拼接到页面上。

如果 args.length === 0，或命令组未罚款，此代码将显示所有类别。 如果组被罚款机器人在组中发送带有命令的嵌入消息（最多 10 个），如果页面超过 1，则响应消息，因此用户可以通过响应更改页面。

   const {Discord,RichEmbed} = require('discord.js');
    const {prefix,token,classic_roles} = require('../config.json');

            let commandCategories = bot.commands.map(command => `!help ${command.help.groups}`).filter(onlyUnique).join('\n') //find all categories and get onlyUnique
            let helpMessage = `**The list of command groups:**\n\n ${commandCategories}`
            let Embed = new Discord.RichEmbed()
                .setAuthor(message.author.tag, message.author.displayAvatarUrl)

            let commandsInCategory = bot.commands.filter(command => command.help.groups === args.join(' ').toLowerCase())
            if(commandsInCategory.size === 0) {
