I've been using the Datepicker plugin from jQuery UI. I want to be able to validate if the input textbox it is attached to currently has a valid date or not.

For example:

If someone decides to type in 02/30/2010 I'd like to be able to somehow ask the plugin if that current input value is a valid date (which it is not in this case).

Does anyone know how this can be done?
