Jquery UI datepicker. Disable array of Dates

IE 8 doesn't have indexOf function, so I used jQuery inArray instead.

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [$.inArray(string, array) == -1];
    }
});

$('input').datepicker({
   beforeShowDay: function(date){
       var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
       return [ array.indexOf(string) == -1 ]
   }
});

You can use beforeShowDay to do this

The following example disables dates 14 March 2013 thru 16 March 2013

var array = ["2013-03-14","2013-03-15","2013-03-16"]

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [ array.indexOf(string) == -1 ]
    }
});

Demo: Fiddle


If you also want to block Sundays (or other days) as well as the array of dates, I use this code:

jQuery(function($){

    var disabledDays = [
       "27-4-2016", "25-12-2016", "26-12-2016",
       "4-4-2017", "5-4-2017", "6-4-2017", "6-4-2016", "7-4-2017", "8-4-2017", "9-4-2017"
    ];

   //replace these with the id's of your datepickers
   $("#id-of-first-datepicker,#id-of-second-datepicker").datepicker({
      beforeShowDay: function(date){
         var day = date.getDay();
         var string = jQuery.datepicker.formatDate('d-m-yy', date);
         var isDisabled = ($.inArray(string, disabledDays) != -1);

         //day != 0 disables all Sundays
         return [day != 0 && !isDisabled];
      }
   });
});
