如何在变量内使用ID

Question

I have been making a user info commmand, and I have just figured out how to get an ID from a mention. This means people can mention others and see their information.

I have placed the ID inside a variable called userid1 , and swapped message.author in favour of userid1 , it runs numerous errors, and when it does work just displays everything as undefined.

I tried using parseInt(userid1) to see if that would change anything but the same issues arose.

My code looks like this:

userid1 = message.mentions.users.first().id;
let embed = new Discord.RichEmbed()
  .addAuthor(userid1.username);

I don't know if it's possible to use a variable as a placeholder for that, so if it is something else please tell me.

The User.id is a string, not the User object itself, so you can't access user properties.
Instead of storing the user id, you could store the user itself: when you need the id you use User.id , but in this way if you need other properties you can access them too.
Also, please note that RichEmbed.addAuthor() does not exist, use RichEmbed.setAuthor() .

Try this:

let target_user = message.mentions.users.first();
if (!target_user) target_user = message.author;
let embed = new Discord.RichEmbed()
  .setAuthor(target_user.username, target_user.avatarURL);
