当有人对表情符号（discord.js）做出反应时，如何编辑消息？

Question

我想创建一个帮助屏幕，您可以使用反应滚动浏览。

---

例如，

1. 如果您对信息表情符号做出反应，机器人的消息将被编辑以显示信息页面。
2. 现在，当有人发送以“;help”开头的消息时，我可以发送帮助消息，并且我可以让机器人对消息做出反应。

但是，我无法让我的机器人删除用户的反应，也无法让其编辑我的消息。

这里是代码。提前感谢您的帮助！

client.on('message', message => {
    if (message.author !== null && message.author.bot) return;
    if (message.toString().startsWith(';help')) {
        const helpPi = new Discord.MessageEmbed()
        .setTitle('Help and commands')
        .setColor('0004ff')
        .setDescription('This is the help menu for available commands. Here is the table of contents:\n> 1 - Commands\n> 2 - More info.')
        const helpP1 = new Discord.MessageEmbed()
        .setTitle('Help and commands')
        .setColor('0004ff')
        .setDescription('Command A\nCommand B')
        const helpP2 = new Discord.MessageEmbed()
        .setTitle('Help and commands')
        .setColor('0004ff')
        .setDescription('More info.')
        message.channel.send(helpPi).then(sentMessage => {
            sentMessage.react('ℹ️')
            sentMessage.react('1️⃣')
            sentMessage.react('2️⃣')
            client.on('messageReactionAdd', reaction => {
                if (reaction == '1️⃣') {
                    sentMessage.edit(helpP1)
                }
                else if (reaction == '2️⃣') {
                    sentMessage.edit(helpP2)
                }
                else if (reaction == 'ℹ️') {
                    sentMessage.edit(helpPi)
                }
            })
        })
    }
});

这可以使用reactionCollectors 来完成。

let mainEmbed;
let penguinEmbed;
let sparklesEmbed;

const sentEmbed = await channel.send(mainEmbed)
await sentEmbed.react('?')
await sentEmbed.react('?')
await sentEmbed.react('✨')
// Adding await will guarantee that everything is in the right order, but it also slows down the operation

// This filter: only accepts the following emojis, and rejects the bot's own reactions
const filter = (reaction, user) => (['?', '?', '✨'].includes(reaction.emoji.name) && !user.bot)
// Define a collector based on that filter for 60s
const collector = sentEmbed.createReactionCollector(filter, {
  time: 60000
}) // for 60s

// Launch it!
collector.on("collect", (reaction, user) => {
  switch (reaction.emoji.name) {
    case '?':
      sentEmbed.edit(mainEmbed);
      break;
    case '?':
      sentEmbed.edit(penguinEmbed);
      break;
    case '✨':
      sentEmbed.edit(sparklesEmbed);
      break;
  }
});

// When it ends, do something.
collector.on("end", (collected) => {

  sentEmbed.edit(
    sentEmbed.embeds[0].setFooter(`This embed is inactive`)
  );

  sentEmbed.reactions.removeAll(); // You can also just remove your bot's reactions, or anything else...
});

这是我很久以前写的代码。我没有编写很多基本的东西来保持代码尽可能小（例如嵌入的定义）
