如何在不和谐的消息中找到一个数字？

Question

I'm making a bot on discord and I want the bot to detect how much the person says in his message and who he mentioned, ex. >command @user 7853. I know that

message.mentions.users.first().id

finds the first-mentioned user but I don't know how to find the number that they said. Can someone tell me the correct script for that?

Answer 1

message.content is the content of the message so you only need to parse that like:

const args = message.content.slice(prefix.length).trim().split(/ +/);
const command = args.shift();

This will convert the message into an array like ['@user', '7853'] . Now you can just do args[1] and you will get the number.
