命令 DM 提到的用户

Question

Here's my code to DM the mentioned members.

const { MessageEmbed } = require("discord.js");

module.exports = {
  name: "dm",
  category: "moderation",
  usage: "DM <@mention> <message>",
  description: "DM server members!",
  run: async (client, message, args) => {
    if (!message.member.hasPermission("MANAGE_ROLES")) {
      return message.channel.send(
        "Access restricted!"
      );
    }

    const targets = message.mentions.members;

    if (!targets) {
      return message.channel.send(
        "Please Mention the person to who you want to DM!"
      );
    }

    if (message.mentions.users.bot) {
      return message.channel.send("You cannot DM bots");
    }

    const reason = args.slice(0).join(" ");

    if (!reason) {
      return message.channel.send(
        "Place provide the message to send!"
      );
    }

    message.channel.send(`DM sent succesfully!`);
      
      let embed = new MessageEmbed()
.setColor('#0099ff')
    .setTitle(`Message from ${message.guild.name}`)
    .setDescription(`${reason}`)
    .setThumbnail('https://i.ibb.co/PCnBZ8w/IMG-20210205-191207.jpg')
    .setFooter(`Sent by ${message.member.user.tag}`)
    
      targets.forEach(target => target.send(embed));
      message.delete();
  }
};

It is used like so: prefixdm the message @mention1 @mention2... . But in the DM received by the users they also get the mentions of the command due my declaration of reason . How can I fix it so that they don't see the mentions in the message?

You can clean up the message using regex. MessageMentions has a USERS_PATTERN property that contains the regular expression that matches the user mentions (like <@82043902196179341> ). You can use it with JavaScript's .replaceAll() method to replace all occurrences of the mention with an empty string:

const reason = args
  .slice(0)
  .join(' ')
  .replaceAll(MessageMentions.USERS_PATTERN, '')
  .trim();

Don't forget to import MessageMentions from discord.js :

const { MessageEmbed, MessageMentions } = require("discord.js");

Update: You can also use .replace() instead of .replaceAll() as the regex globally matches user mentions. Source .
