jquery fullcalendar

Question

I am trying to integrate jquery full calendar plugin.. And I want to disable the past dates for selection.. So I can select only dates starting from current date. How is it possible? How can I filter the dates and specify a condition. I am new to jquery.

$(document).ready(function() {
    var date = new Date();
    var d = date.getDate();
    var m = date.getMonth();
    var y = date.getFullYear();

    var calendar = $('#calendar').fullCalendar({
        header: {
            left: 'prev,next today',
            center: 'title',
            right: 'month,agendaWeek,agendaDay'
        },
        selectable: true,
        selectHelper: true,
        select: function(start, end, allDay) {
            var title = prompt('Event Title:');
            if (title) {
                calendar.fullCalendar('renderEvent',
                    {
                        title: title,
                        start: start,
                        end: end,
                        allDay: allDay
                    },
                    true // make the event "stick"
                );
            }
            calendar.fullCalendar('unselect');
        },
        editable: true,
    });
});

Answer 1

In the select method, you are provided with the selected start and end date, and earlier in the method you got the current date in the date variable. So just compare them, and if it is less than date, handle the error.

select: function(start, end, allDay) {
  if(start < date)
  {
    // Do whatever you want here.
    alert('Cannot select past dates.');
    return;
  }

  var title = prompt('Event Title:');
  if (title) {
    calendar.fullCalendar('renderEvent', {
        title: title,
        start: start,
        end: end,
        allDay: allDay
      },
      true // make the event "stick"
    );
  }

  calendar.fullCalendar('unselect');
},

Note regarding Brandon's answer, the popup will also appear if you click on the current date. You would need to check if the user clicked on today's date also:

if (start < date && start.getDate() != date.getDate() ) {
    alert('Cannot select past dates.');
    return;
}
