I need a single regex to check number comma and number

I need a regX which can match like 123,123 only. My regX is

var regX = /^\d*[0-9](|.\d*[0-9]|,\d*[0-9])*$/;

but its currently matching 123,123 and 123, as well

Valid case: 123,123 or 123,000 or 000,000 Invalid case: 123.123 or 123?123 or '123'.'123'

If your numbers are positive integers you can use: \d+,\d+ If you want floating point numbers as well: (\d|.)+,(\d|.)+ although this will also match malformed numbers with multiple or misplaced decimal points including .,. etc.

It looks like you're actually trying to match a number with thousand separators.

Try this: /\d{1,3}(?:,\d{3})*/

You might want to use the {x,y} quantifier. I matches at least X of the item, and at most Y. If you leave one out, it has no limit in that direction. If you just have one number, with no comma it matches exactly that amount.

Exactly three digits:

(\d{3}),(\d{3})

Three or more

(\d{3,}),(\d{3,})

Between 2 and 7 digits:

(\d{2,7}),(\d{2,7})

And so on...
