how to validate number format based on the locale defined in javascript

Question

I have input text field (type = string) which should accept number as input but the number format should be validated based on the defined locale code.

var number = '2,110.168';
if locale is en-in, this should be valid
if locale is nl-nl, this is not a valid format as it should be 2.110,168

What version of Angular is this, are you using reactive forms and what have you tried? — Reactgular, Jan 31 '19 at 13:55
Is the comma in 2,110.168 a requirement? Will there be a random amount of decimal places as well? — Eric Svitok, Jan 31 '19 at 14:00

You can use Number.toLocaleString() which returns the "language-sensitive representation" of a number.

If your input is in a form, you can create a custom validator to validate its value.
