ABN Validation

Hi thanks for your time.

I am wondering if you might be able to help me. Do you know of a JQuery solution that can validate an Australian Business Number (ABN). Here is a Javascript version that I have managed to find, but I can not seem to find a JQuery version. It would be preferable if it was contained in the one field rather than over 4.
