regex for money values in JavaScript

rated 0 times [ 95] [ 7] / answers: 1 / hits: 33809 / 12 Years ago, fri, august 3, 2012, 12:00:00

Been out of the regex game for a while. Trying to come up with something that will allow the user to enter a money value either with/without dollar sign or with/without commas. For example, all the of the following values should be valid:

5

5.1

5.10

$5

500,000

500,000.1

500,000.10

$100,000,000.50

etc....

Could someone please help me out?

This should work:

isValid = str.search(/^$?[d,]+(.d*)?$/) >= 0;

A little more strict with comma placement (would reject 3,2.10, for example):

isValid = str.search(/^$?d+(,d{3})*(.d*)?$/) >= 0;

To get a number out of it:

if(isValid) {

  var num = Number(str.replace(/[$,]/g, ''));

  ...

}
