Commas messing with number input in Javascript

I have a page with some elements that are controlled by the user. One of these is a text input field, where the user is supposed to input a number. Everything works well if the user only inputs digits (EG 9000), but is the user uses comma notation (the being 9,000) javascript doesn't take the input as an integer.

How can I remove the commas and/or force the input to an integer? I tried using parseint(), but it doesn't seem to work with commas.

Use a global regular expression to replace all commas with an empty string:

var str = 12,345,678;

str = str.replace(/,/g, );

parseInt(str, 10);
