Javascript regex for accepting only number without "," or "." character

Question

I'm looking for a regex javascript expression for allowing only numbers at this format 1234. Not 1,234 or 1.234. I'm having this regex now but it does not seem to work properly /[a-z]/i

Sorry, but what does `/[a-z]/i` regex has to do with numbers? What was your intent? How did you use it? — Wiktor Stribiżew, Jun 14 '17 at 06:09

var reg = /^\d+$/;

should do it. The original matches anything that consists of exactly one digit.
