Question

I would like to a regular expression to use with javascript replace function that separe with a space each 2 number I type

Input Ex.: 01020304050607

Output Ex.: 01 02 03 04 05 06 07

How could I do it?

Answer 1

/(\\d{2})/g should do the trick. Example:

> "021651984984984984".replace(/(\d{2})/g, "$1 ").trim()
"02 16 51 98 49 84 98 49 84"

Answer 2

Something like this?

var numbers = "0203040506";
var numbersString = numbers.replace(/([0-9]{2})(?=.)/g,"$1 ");
