I did it in a way too complicated way, but it does not involve regex so it's probably better to understand:

let str = "url(#123456)";
str = str.split("#");
str = str[1].split(")");
str = str[0];
console.log(str);

Using only Array methods:

console.log("url(#123456)".split('#').pop().slice(0, this.length -1))
