[jQuery] Quick Question about the ui.datepicker

[jQuery] Quick Question about the ui.datepicker


Hi there's a couple of things that id like to ask.
Here is my code:
$(function()
{
    $('#deliverydate').datepicker({
minDate: +1,
maxDate: '+1Y',
changeMonth: true,
             changeYear: true,
             showOn: 'both',
             buttonImage: '../../images/general_images/calendar.jpg',
buttonImageOnly: true,
altField: '#actualDate',
altFormat: 'yy-mm-dd',
});
});
basically I want the user to see the date in the 'dd-mm-yy
format' (this already happens) but i want the post information to be
in the 'yy-mm-dd format'.
The document (http://docs.jquery.com/UI/Datepicker/datepicker#options)
suggests:
Display one date format and send another from a different field.
$(".selector").datepicker({
altField: '#actualDate', altFormat: 'yy-mm-dd' })
Which i've added, but how would i access that data when the form is
posted?
Thanks for any help
