str.replace(/[^0-9]/g, '')

let str = "url(#123456)";
console.log(str.replace(/[^0-9]/g, ''))

another way to do it

let str = "url(#123456)";

console.log(str.match(/\d+/)[0])

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))
