regex for numbers comma and space

Question

I have a text area and a user can input US zip codes in it separated by a comma or (comma and space).

It could be like 12345,45678, 89654

The following regex is working and is removing not allowed characters:

$object.val($object.val().replace(/[^\d\, ]/g, ''));

I would like to enhance it, so that

i always should have 5 digits in the beginning
after 5 digits, there should be a comma or comma and space
comma or (comma and space) should not be at the very end of the string. It must be 5 digit number at the end.

This needs to tackle the copy paste as well. The user may copy paste invalid length for the zip code.

Thanks

Have you thought about the jQuery maskedinput plugin? It works great for me, and I've had no conflicts. http://digitalbush.com/projects/masked-input-plugin/ — TimSPQR, Sep 27 '13 at 14:56
have you tried searching SO for possible answers that could help you accomplish this? how about the one here - http://stackoverflow.com/questions/160550/zip-code-us-postal-code-validation/160583#160583 — Zathrus Writer, Sep 27 '13 at 14:57
Instead of cropping input texts, I would recommend just to show when they are invalid. — Bergi, Sep 27 '13 at 14:58
You are ignoring the new 9 digit (preferred) zip code:12345-5432 . Is that a good idea? — Floris, Sep 27 '13 at 14:58

Use this regex: ^\d{5}(, ?\d{5})*$

It specifies 5 digits at the beginning: ^\d{5} and any number of other comma, space, and 5 digit combinations: (, ?\d{5})*

You can use:

var s='12345,45678, 12345';
var m = s.match(/^(?:\d{5},\s?)*\d{5}$/);

I need to restrict not allowed chars while the user is entering the numbers. This is good for validation on blur or submit. – learning... Sep 27 '13 at 15:36
Didn't get your comment. This will not allow any not-allowed character. – anubhava Sep 27 '13 at 15:38
