How do I get the 4 digit user ID of a discord user?

Question

I'm wondering how I can get the 4 digit user ID of a discord user from a message. For example, PruinaTempestatis#8487. Can someone help me?

Answer 1

If the number always appears after a single hash # then you can simply do a split on that string and get the second value of the array like this:

USING SPLIT

 var str = 'PruinaTempestatis#8487'; var digits = str.split('#')[1]; console.log(digits);

USING REGEX

 var str = 'PruinaTempestatis#8487'; var digits = str.replace( /^\D+/g, ''); console.log(digits);

USING SUBSTRING

 var str = 'PruinaTempestatis#8487'; var digits = str.substr(str.indexOf('#')+1, str.length); console.log(digits);

Answer 2

Using user.tag

message.channel.send(message.user.tag)

Answer 3

Split their tag into an array and get the last element.

member.user.tag.split('#')[-1];
