Validate and change

I am trying to set up my page to validate that the Currency input the user
put in is valid and to also change the field to readable format. I would
like to do this without going back to the server and make the change when
the user tabs out of the field.

For example:

I want to be able to recognize:
10000
$10000
10,000
10,000.00
10K

I would like to reformat the above as
10,000 or as $10,000.

I assume I would have to do this in Javascript, but not sure how to connect
it to the field to do this as he is leaving and not postback.

Thanks,

Tom
