How To Disable Specific Days and Dates Using BeforeShowDay In jQueryUiDatepicker? - datepicker

Question

I already have functioning code in jQueryUiDatepicker that disables Fridays and Saturdays and all previous days (plus 2 days). My issue is trying to add 2 specific dates to this existing Datepicker code that will also disable these dates.
This is my existing code on starting line 92 in jQueryUiDatepicker:
beforeShowDay: function(date) {
var show = true;
if(date.getDay()==5||date.getDay()==6) show=false
return [show];
},
beforeShow: function(){
var dateTime = new Date();
var hour = dateTime.getHours();
//If Hour is greater or equals to 8AM
if(hour >= 08){
//Disable all past days including tomorrow and today
$(this).datepicker( "option", "minDate", "+2" );
}
},
I am trying to disable 18th and 19th October 2017 and failing, this is the code I have added directly underneath the above code:
beforeShowDay: var array = ['18/10/2017', '19/10/2017']
$('input').datepicker({
beforeShowDay: function(date){
var string = jQuery.datepicker.formatDate('dd/mm/yy', date);
return [ array.indexOf(string) == -1 ]
},
My question is how can I disable all previous dates, all Fridays and Saturdays and these 2 dates in the October?
Note# This coding has to be done in jquery.ui.datepicker, not a script in html

Hope this helps
use inArray instead of indexOf and you can also disable all previous dates using minDate
var array = ["18/10/2017", "19/10/2017"];
$(function() {
$('input').datepicker({
minDate: new Date(),
beforeShowDay: function (date) {
$thisDate = date.getDate() + "/" + (date.getMonth() + 1) + "/" + date.getFullYear();
var day = date.getDay();
if ($.inArray($thisDate, array) == -1&&day!=5&&day!=6) {
return [true, ""];
} else {
return [false, "", "Unavailable"];
}
}
});
});
