jQuery Ui beforeShowDay - Disable Certain Dates - php

Question

I am using an Ajax call to PHP to return a string of dates that a user is available, To make it dynamic.
I am returning the string back to my jQuery as :
['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 I initialise the datePicker, That string of dates does not load.
I am not too sure as to why, I suspect its my success function after my Ajax call.
My jQuery code looks like this :
$('.vendor_id').change(function()
{
var vendor_id = $('option:selected', this).attr('title');
var url = "/admin/po/get_user_dates/" + vendor_id;
$.ajax({
type : "POST",
url : url,
success: function(unavaildates)
{
var disabledDays = unavaildates;
function disableAllTheseDays(date) {
var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
for (i = 0; i < disabledDays.length; i++) {
if($.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 someone call help me on this.
Quick Update.. On assigning disabledDays to ['7-15-2013','7-16-2013','7-17-2013','7-18-2013','7-19-2013','7-20-2013','7-21-2013','7-22-2013'] the datePicker works...?
Thanks in advance.

Answer 1

Because you are retrieving a string and not an array from the server.
I would suggest to return the 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'" from the server and create the array like this :
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(',');
