jQuery UI Datepicker - Disable specific days

Question

Is there any (easy) way to set the jQuery UI Datepicker to disallow selection of specific, predetermined days?

I was able to get this approach working, however, it produces a null error which prevents it from displaying in IE.

'natDays[...].0' is null or not an object

Thanks in advance!

UPDATE: Might help if I included some code, right? Anyway, most of this was taken straight from the aforementioned thread:

natDays = [
        [7, 23], [7, 24], [8, 13], [8, 14], 
    ];

    function nationalDays(date) {
        for (i = 0; i < natDays.length; i++) {
            if (date.getMonth() == natDays[i][0] - 1
            && date.getDate() == natDays[i][1]) {
                return [false, natDays[i][2] + '_day'];
            }
        }
        return [true, ''];
    }

    function noWeekendsOrHolidays(date) {
        var noWeekend = $.datepicker.noWeekends(date);
        if (noWeekend[0]) {
            return nationalDays(date);
        } else {
            return noWeekend;
        }
    }


    $(function() { 
        $("#datepicker").datepicker({
            inline: true,
            minDate: new Date(2009, 6, 6), 
            maxDate: new Date(2009, 7, 14), 
            numberOfMonths: 2, 
            hideIfNoPrevNext: true,
            beforeShowDay: $.datepicker.noWeekends,
            altField: '#alternate',
        }); 
    });

Thanks again!

Here is a way to disable specific dates from being selected:

var unavailableDates = ["9-5-2011","14-5-2011","15-5-2011"];  function unavailable(date) {   dmy = date.getDate() + "-" + (date.getMonth()+1) + "-" + date.getFullYear();   if ($.inArray(dmy, unavailableDates) < 0) {     return [true,"","Book Now"];   } else {     return [false,"","Booked Out"];   } }  $('#iDate').datepicker({ beforeShowDay: unavailable });

Have you tried declaring natDays properly with the 'var' keyword in front?

Also - you have an extra comma at the end of your natDays definition.

natDays[i][2] won't work as your the arrays only have 2 items in them - try just ''

Additionally, you'll want to set your beforeShowDay function name correctly - doesn't look like it's even calling your custom function

You can use the beforeShowDay option. I needed to disable any day past the 28th of the month. Here is my code.

$('.datepicker').datepicker({
    dateFormat: "yy-mm-dd",
    beforeShowDay: function(date) {
        var day = date.getDate();
        if (day > 28) {
            return [false];
        } else {
            return [true];
        }
    }
});

Here is more information about it: http://api.jqueryui.com/datepicker/#option-beforeShowDay

The date variable passed into the beforeShowDay callback is a JavaScript date object, so it can be formatted using various libraries, a timestamp can be retrieved using date.getTime(), etc.
