php - jQuery Ui beforeShowDay - Disable Certain Dates -

i using ajax call php return string of dates user available, make dynamic.

i returning string jquery :

['7-15-2013','7-16-2013','7-17-2013','7-18-2013','7-19-2013','7-20-2013','7-21-2013','7-22-2013'] 

however when initialise datepicker, string of dates not load.

i not sure why, suspect success function after ajax call.

my jquery code looks :

$('.vendor_id').change(function()     {         var vendor_id = $('option:selected', this).attr('title');          var url = "/admin/po/get_user_dates/" + vendor_id;          $.ajax({             type : "post",             url  : url,             success: function(unavaildates)             {                 var disableddays = unavaildates;                  function disableallthesedays(date) {                     var m = date.getmonth(), d = date.getdate(), y = date.getfullyear();                     (i = 0; < disableddays.length; i++) {                         if($.inarray((m+1) + '-' + d + '-' + y,disableddays) != -1) {                             return [false];                         }                     }                     return [true];                 }                   $('.booking-date').datepicker(                         {                             beforeshowday: disableallthesedays,                             numberofmonths: 2,                             dateformat: 'dd, d mm, yy',                             showbuttonpanel: true                         }                 )              }         })     }) 

hope call me on this.

quick update.. on assigning disableddays ['7-15-2013','7-16-2013','7-17-2013','7-18-2013','7-19-2013','7-20-2013','7-21-2013','7-22-2013'] datepicker works...?

thanks in advance.

because retrieving string , not array server.

i suggest return string without square brakets "'7-15-2013','7-16-2013','7-17-2013','7-18-2013','7-19-2013','7-20-2013','7-21-2013','7-22-2013'" server , create array :

var unavaildates = "'7-15-2013','7-16-2013','7-17-2013','7-18-2013','7-19-2013','7-20-2013','7-21-2013','7-22-2013'" var disableddays = unavaildates.split(',');
