Hello,

i am using this code found in this forum :

$('#startsession').datepicker({ 
         minDate : 0,
         maxDate : '+1D',
         firstDay : 0,
          dateFormat: 'yy-mm-dd', 
          buttonImage: '../datepicker/calendar.gif',  
          showOn: 'both', 
          onSelect: function(date) { 
            var daystart = $("#startsession").datepicker("getDate");
            daystart.setDate(daystart.getDate());

            $("#endsession").datepicker("option","minDate",daystart).datepicker("setdate", daystart).val(date);

      }         
       }); 

        $('#endsession').datepicker({      
         minDate : 0,
         maxDate : '+1D',
         firstDay : 0,
         dateFormat: 'yy-mm-dd', 
         buttonImage: '../datepicker/calendar.gif',  
         showOn: 'both'        
       }); 

If today is 2010-02-09, when i choose a date (session beginning. ex.: 2010-02-18) in the first datepicker then i can't choose the same day (2010-02-18) or the following day (2010-02-19) in the second datepicker (session ending). I could change the maxDate in the init of the two datepickers to a number of days high enough to solve all possibilities but it permits to choose a date after the real end of a session. 

Ex. : a user choose 2010-02-18 in the first datepicker then i would like that he can only choose a date between 2010-02-18 and 2010-02-19 for a session of one or two days.

In the future the number of session days will be between 1 and 105 then the max number of days will be set by a variable.


I tried to set a maxDate after the date is selected in the first datepicker like the way i set minDate but it did not work.

I calculate the date of the session end, put it in a variable endmaxdays and tried to set maxDate this way :

$("#endsession").datepicker("option","maxDate",  endmaxdays);

It did not work.

i also tried to set maxDate with a value :

$("#endsession").datepicker("option","maxDate",  "2010-02-19");

I tried many other ways, none worked.

So i think that i am doing a basic mistake.

Help will be appreciated.

Thanks
