jquery date picker split into multiple fields

Question

I have the usual Jquery datepicker working fine. But I want to feed it into a set of selectboxes rather than one textfield. I have had success feeding it into one select field with a specific format but am unsure how to feed all three into different fields with different formats.

$(document).ready(function(){
  $("#search_startdate").datepicker({showOn: 'button', 
                                     buttonImage: '/images/cal/calendar.gif', 
                                     buttonImageOnly: true, 
                                     minDate: 0, 
                                     maxDate: '+6M +10D', 
                                     showAnim: 'fadeIn',
                                     altField: '#startdate_month', 
                                     altFormat: 'MM',
                                     altField: '#startdate_day',
                                     altFormat: 'dd'});
    //$("#datepicker").datepicker({showOn: 'button', buttonImage: 'images/calendar.gif', buttonImageOnly: true});

});

This doesn't work, it works on the last field, but ignores the first. If I remove the second set of altField and altFormat lines, the first works.

I also tried putting them in a series,

altField: '#startdate_month', '#start_day', altFormat: 'MM', 'dd'

The problem is the same as here:

Any ideas?

Thanks,

I'd suggest using your set up with a single alternate field to get the first select, then using an onClose handler to parse the date and fill the other selects.

$(document).ready(function(){
  $("#search_startdate").datepicker({showOn: 'button', 
                                     buttonImage: '/images/cal/calendar.gif', 
                                     buttonImageOnly: true, 
                                     minDate: 0, 
                                     maxDate: '+6M +10D', 
                                     showAnim: 'fadeIn',
                                     altField: '#startdate_month', 
                                     altFormat: 'MM',
                                     onClose: function(dateText,picker) {
                                                 $('#startdate_day').val( dateText.split(/\//)[1] );
                                              }
                                    });
});

This is simpler I think:

$('#datePickerField').datepicker({
    onClose: function (dateText) {
                var objDate = new Date(dateText);
                $('#year_field').val(dateText.length ? objDate.getFullYear() : '');
                $('#month_field').val(dateText.length ? objDate.getMonth() + 1 : '');
                $('#day_field').val(dateText.length ? objDate.getDate() : '');
            }
});

and if you want changes made to day,month,year fields update the main datapicker:

$('#year_field,#month_field,#day_field').change(function() {
    $('#datePickerField').datepicker('setDate', new Date(
        parseInt($('#year_field').val(), 10),
        parseInt($('#month_field').val(), 10) - 1,
        parseInt($('#day_field').val(), 10)));
});
