You assign the return value and use that for example. str = str.replace(/[^0-9]/g,'');

or waiting for the original line to change?

String functions do not modify the original string, they return modified strings.

It worked, try pasting in your browser's location field:

javascript:alert("item number:237728".replace(/[^0-9]/g,""))

As Neil says, I suspect your problem might be a string mutability issue. Make sure you grab the return value from replace()
