jQuery UI Datepicker enable only specific days in array

Question

I am trying to disable all dates in a datepicker and only enable dates which are in an array. This is the code I have so far http://jsfiddle.net/peter/yXMKC/ the problem is only May 14th shows up as enabled. The others are all disabled. Any ideas?

var availableDates = ["9-5-2011","14-5-2011","15-5-2011"];

function available(date) {
  dmy = date.getDate() + "-" + (date.getMonth()+1) + "-" + date.getFullYear();
  if ($.inArray(dmy, availableDates) == 1) {
    return [true, "","Available"];
  } else {
    return [false,"","unAvailable"];
  }
}

$('#date').datepicker({ beforeShowDay: available });

Answer 1

$.inArray(dmy, availableDates) returns the index of the element, so when you compare with 1 only 14-5-2011 will match. Check for not equal to -1. Should work.

Fiddle - http://jsfiddle.net/yXMKC/4/

var availableDates = ["9-5-2011","14-5-2011","15-5-2011"];

function available(date) {
  dmy = date.getDate() + "-" + (date.getMonth()+1) + "-" + date.getFullYear();
  console.log(dmy+' : '+($.inArray(dmy, availableDates)));
  if ($.inArray(dmy, availableDates) != -1) {
    return [true, "","Available"];
  } else {
    return [false,"","unAvailable"];
  }
}
