Commas messing with number input in Javascript

Question

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

Answer 1

maybe

 parseint(ny9000withCommas.replace(/\,/g,""))

lets talk about the restriction :

you can/should allow the user to enter both 9000 & 9,000

you can check validy via REGEX.

in the server side - you should eleminate the commas and treat it as integer.

Answer 2

Or even better, given the general unreliability of user input, use this to get rid of all non-numeric characters:

var s = "9,Ljk876";
var t = parseInt(s.replace(/[^0-9]/g, ''));
alert ("s:" + s + ", t:" + t);

Answer 3

or even better

var s="jdjsghd0182.99";
var str = parseFloat(s.replace(/[^0-9 | ^.]/g, ''));

Answer 4

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);
