Question

I didn’t get a suitable regex that enable to split such string:

72 g tocirah snaeb 101 sgge 108 g darl 111 spuc loi 32 sinihccuz

into strings basing on numbers first occurences like so:

72 g tocirah snaeb, 101 sgge, 108 g darl, 111 spuc loi, 32 sinihccuz 

How can i do that:

var str="72 g tocirah snaeb 101 sgge 108 g darl 111 spuc loi 32 sinihccuz";
var regex="/  /";
var result=str.match(regex);

Answer 1

Use:

var result=str.replace(/ (\d+)/gm, ", $1");

Search pattern: search an space char followed by one or more numbers and capture the number.

 / (\d+)/gm

Replace: replace by a , followed by the captured number.

, $1
