now I begin learning regex, and I have set of string in format like "(9/13)", and I need get second number. I try this regex: /\(.*?[^\d]*(\d+?)\)/g, in online regex it works normally.

But here:

var d = "(9/13)";
var v = /\(.*?[^\d]*(\d+?)\)/g;
alert(d.match(v));

it returns "(9/13)" , what am I doing wrong?

  • You really could just use https://regex101.com/r/mFGYcA/2/codegen?language=javascript and keep only what you need. If you are using regex101, use all of its power. – Wiktor Stribiżew Aug 22 '17 at 11:03

const source = "(9/13)";

const re = /\/(\d+)\)/;

console.log('result', re.exec(source).pop())

you can use Regex.exec() to find the number 

const source = "(9/13)";

const re = /\(\d+\/(\d+)\)/;

console.log(re.exec(source)[1])
