Hi all,

I have a javascript DatePicker and I need to customise the date selection. I want to have available only fridays for selection and when the date is greater that the 15 it enables the first friday of next month as well.

So for example if the todays date is less than the 15 i want to be able to select only this months fridays if it is greater that the 15 i want to be able to select this months fridays and the first friday of next month.

Thanks for your help. I tried this code out but it didn't work

function pageLoad() {
           $(function () {
               $("#dp").datepicker({ dateFormat: 'dd/mm/yy', beforeShowDay: nextMonthFriday, onSelect: function (dateText, inst) { __doPostBack('DatePicker', '') } });
           })
       }

       function nextMonthFriday(date) {
       var d = new Date();
       var d1 = new Date();

       d = now.getDate();
       var d2 = d.getDay();
       if (d >= 15)
       {
           d1 = new Date(now.getFullYear(), now.getMonth() + 1, 1);
           d2 = d1.getDay();


           return[(d2 == 5 && (d1.getDate() <= 7)),''];
       }

       return [(false), ''];
       }


       function onlyFridays(date) {
           var day = date.getDay();
           var d = date.getDate();

           if (day == 5 )
               return [(date <= FridayWeek()), ''];




           return [(false), ''];
       }


       function FridayWeek()
       {
           var d = new Date();

           while (d.getDay() != 5)
           {
               d.setDate(d.getDate() + 1);
           }

           d.setDate(d.getDate() + 7);

           return d;
       }
