Is it possible in javascript regex, to match string inside the string matched by my capture group?

-3

I have following string dfed operator 11 - 145. I am trying to match string operator 11 and inside this matched string, i am trying to match string 11. Currently I successfully matched operator 11 with regex ((O|o)perator(i|I)?s*)d+(?=s*(-|_)s*d+). As I am in javascript, I can not use lookbehinds.

Is my approach correct? Is there any way to accomplish this in regex? How can i match string 11 inside previously matched string operator 11?

Thank you

@PoulBak If OP uses match with g, OP won't have the access to captured values. Thus, OP must learn how to do it, hence the link is provided.

You can modify your regex by creating a group for the first number in the matched string:

const str = 'dfed  operator  11 -  145';

const regex = /([O|o]perator)[i|I]?s*(d+)*[?=s*(-|_)s*d+]/;

const found = str.match(regex);



console.log(found);

console.log(found[1]); // <-- group for string

console.log(found[2]); // <-- group for number

The match twice is just for the code example

You could use (mind the case insensitive flag in the demo):

operatorD+(d+)
