Convert String with Dot or Comma as decimal separator to number in JavaScript

Question

An input element contains numbers a where comma or dot is used as decimal separator and space may be used to group thousands like this:

\'1,2\'

Answer 1

You could replace all spaces by an empty string, all comas by dots and then parse it.

var str = "110 000,23";
var num = parseFloat(str.replace(/\s/g, "").replace(",", "."));
console.log(num);

I used a regex in the first one to be able to match all spaces, not just the first one.
