Datepicker for web page that can allow only specific dates to be clicked

however, when I implement it, I get the following error: TypeError: Result of expression 'date.getMonths' [undefined] is not a function.

I'm testing using the same versions of jquery (1.4.4) and jquery ui on jquery ui's official site any help is greatly appreciated!

$.datepicker.setDefaults({maxDate: (new Date(2011, 3, 2))});

    $('#Date').datepicker({

    // called for every date before it is displayed
    beforeShowDay: function(date) {

        var date_str = [
            date.getFullYear(),
            date.getMonths() + 1,
            date.getDay()
        ].join('-');

        if (dates_allowed[date_str]) {
            return [true, 'good_date', 'This date is selectable'];
        } else {
            return [false, 'bad_date', 'This date is NOT selectable'];
        }
    }
});

That would be because it's .getMonth, singular.

Most likely a typo.

use date.getMonth()
