Javascript Regex for Indian price validation

Question

I want to validate price format which can have values as eg. ₹ 3.50L,₹ 3.50, ₹ 3.50Cr,₹ 99.50L, ₹ 3L,₹ 300.50Cr, ₹ 350Cr, ₹ 3,50,000 ,₹ 1

I have tried this Regex : ^₹ ([0-9]+(,[0-9]+)*|[0-9]+(.[0-9]+)*(L|Cr))+$ which should fail for price ₹ 3,50L but it still show as pass.

What changes I need to make

Could you describe your rules in human-readable sentences? Also I don't quite get your use of point and comma. — Hubert Grzeskowiak, Jan 11 '17 at 11:05
Why do you think it should fail for the price `₹ 3,50L`? According to the regex you have there `([0-9]+(,[0-9]+)` and it fits the `3,50` — Dekel, Jan 11 '17 at 11:09
Maybe [`^₹ [0-9]+(?!,[0-9]+(?:L|Cr)?$)(?:,[0-9]+)*(?:\.[0-9]+)?(?:L|Cr)?$`](https://regex101.com/r/LVKHz7/2)? — Wiktor Stribiżew, Jan 11 '17 at 11:10
price ₹ 3.50 is equivalent to $ 3.50 and if number has comma(,) then if should not be follwed by L or Cr. Also, number could either have . or , at a time followed by any number. — Software test engineer, Jan 11 '17 at 11:11
As already commented by Hubert Grzeskowiak, describe your rules in human-language so it will be possible to write the relevant regex according to what you are looking for. — Dekel, Jan 11 '17 at 11:16

Hi @WiktorStribiżew , your regex works for all cases except price ₹ 3,500 — Software test engineer, Jan 11 '17 at 11:18
@WiktorStribiżew cases below ₹ 3,50L should not match: https://regex101.com/r/LVKHz7/4 — Software test engineer, Jan 11 '17 at 11:37

Following regex will get your work done:

^₹ (([0-9]+\,[0-9]+)|([0-9]+[.]?[0-9]*(?:L|Cr)?))$

([0-9]+\,[0-9]+) : Will match values where ',' is used without L or Cr.

([0-9]+[.]?[0-9]*(?:L|Cr)?) : Will match values with L or Cr. Here '.' may or may not be used.
