How can I make first date max of second date

I would like to run this code but without success. I'm a beginner please!
Indeed, I have two dates date1 and date2. and I would like after selecting date date1 that date to be the max date of date date2. I tried with it but it does not work (Onchange)
$(document).ready(function() {
// Date1
$(".date1").datepicker({
todayBtn: 1,
autoclose: true,
}).on('changeDate', function(selected) {
var minDate = new Date(selected.date.valueOf());
$('.date2').datepicker('setStartDate', minDate);
});
// Date2
$(".date2").datepicker({
todayBtn: 1,
autoclose: true,
}).on('changeDate', function(selected) {
var minDate = new Date(selected.date.valueOf());
$('.date1').datepicker('setStartDate', minDate);
});
});

Bootstrap datetimepicker disable future date and time

I am trying to disable future hours within today using disabledTimeIntervals but it doesn't seem to work.
What I need to do is disable future hours in timepicker for today only, because disabling dates I can do with maxDate.
<input class="form-control input-sm pull-left " id="dp" placeholder="To" type="text">
$('#dp').datetimepicker({
maxDate: '0',
disabledTimeIntervals: [[moment(), moment().hour(24).minutes(0).seconds(0)]],
format: 'm/d/Y H:i A',
timepicker: true,
});
JSFIDDLE: https://jsfiddle.net/3oxmccjq/1/

You can use maxTime option and function onChangeDateTime to set the minTime according to the selected date.
The comparison between dates is up to you :-)
var today = new Date();
var options = {
maxDate: new Date(),
maxTime: new Date(),
disabledTimeIntervals: [
[moment(), moment().hour(24).minutes(0).seconds(0)]
],
format: 'm/d/Y H:i A',
timepicker: true,
onChangeDateTime: function(date) {
// Here you need to compare date! this is up to you :-)
if (date.getDate() === today.getDate()) {
this.setOptions({maxTime: new Date()});
} else {
this.setOptions({maxTime: false});
}
}
};
$('#dp').datetimepicker(options);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-datetimepicker/2.5.4/build/jquery.datetimepicker.full.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<input class="form-control input-sm pull-left " id="dp" placeholder="To" type="text">

The datetimepicker you are using in your jsfiddle have no options as disabledTimeIntervals and that's why it is not working. You should use disabledMinTime & disabledMaxTime
As for the solution I am guessing you want to disable all future hours for today but still want to allow future dates with all the possible time. Here is a jsfiddle for same :-
https://jsfiddle.net/sahilbatla/zpzL2po3/
Code looks like this :-
var today = new Date();
var todayEndOfDay = new Date().setHours(23,59,59,999);
$('#dp').datetimepicker({
disabledMinTime: today,
disabledMaxTime: todayEndOfDay,
format: 'm/d/Y H:i A',
timepicker: true,
onChangeDateTime: function(date) {
if (date.getDate() !== today.getDate()) {
this.setOptions({disabledMinTime: false, disabledMaxTime: false})
} else {
this.setOptions({disabledMinTime: today, disabledMaxTime: todayEndOfDay})
}
}
});

jQuery datepicker specific date disable is not working

I have code to disable specific dates on jquery datepicker. code runs fine on my local environment but not working on GoDaddy windows hosting
var disableddates = result; //result is array of dates ["1/7/2018","1/8/2018","1/9/2018"]
$("#txtFromdate").datepicker({
minDate: 0,
beforeShowDay : DisableSpecificDates
});
$("#txtTodate").datepicker({
minDate: 0,
beforeShowDay : DisableSpecificDates
});
function DisableSpecificDates(date) {
var string = jQuery.datepicker.formatDate('mm/dd/yy', date);
console.log(string); //this string return with leading zero 01/07/2018...
return [disableddates.indexOf(string) == -1];
}
This code run fine on local but when making it live it is not disabling specific dates in jQuery datepicker.

You do not need to format the date if it's already in a date format. For example, if result contains an array date like "1/7/2018", you can create a Date object from this:
var newDate = new Date(result[0]);
With this in mind, you can easily make and manipulate a Date. DatePicker passes a Date object to the function too. Here is a solution you might try:
$(function() {
var disableddates = ["1/7/2018", "1/8/2018", "1/9/2018"];
$("#txtFromdate, #txtTodate").datepicker({
minDate: 0,
beforeShowDay: DisableSpecificDates,
dateFormat: "m/d/yy"
});
$("#txtFromdate").change(function() {
$("#txtTodate").datepicker("option", "minDate", $(this).val());
});
function DisableSpecificDates(date) {
var result = [true];
$.each(disableddates, function(k, v) {
var exclude = new Date(v).toString();
var today = date.toString();
if (exclude == today) {
console.log("Match", exclude, today);
result = [false];
}
});
return result;
}
});
label {
width: 60px;
}
input {
width: 10em;
}

Hope that helps.

Is it possible to update unavailable days without destroy jquery datepicker

I have jQuery Datepicker with unavailable dates:
var disabledDates = ["23.05.2017", "24.05.2017"];
$("#datepicker").datepicker({
beforeShowDay: function(date) {
var string = jQuery.datepicker.formatDate('dd-mm-yy', date);
return [disabledDates.indexOf(string) == -1];
}
});
The only way i found to update disabledDates was to destroy datepicker, update unavailable dates and re-init.
// Destroy
$("#datepicker").datepicker("destroy");
// Update unavailable times
disabledDates = ["23.05.2017", "24.05.2017", "25.05.2017", "26.05.2017"];
// Re-init
$("#datepicker").datepicker({
beforeShowDay: function(date) {
var string = jQuery.datepicker.formatDate('dd-mm-yy', date);
return [disabledDates.indexOf(string) == -1];
}
});
Is there a other/better way to do it?

You don't need to destroy it, simply change the beforeShowDay property, see following please:
var disableddates = ["20-05-2017", "21-05-2017"];
function DisableSpecificDates(date) {
var string = jQuery.datepicker.formatDate('dd-mm-yy', date);
return [disableddates.indexOf(string) == -1];
}
$(function() {
$("#datepicker").datepicker({
beforeShowDay: DisableSpecificDates
});
});
$("#btn1").click(function(){
disableddates = ["01-05-2017", "02-05-2017"];
$("#datepicker").datepicker({
beforeShowDay: DisableSpecificDates
});
console.log("Disabled dates changed");
});
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<p>Date: <input type="text" id="datepicker"></p>
<input type="button" id="btn1" value="Change dates">
I hope it helps you, bye.

Air Datepicker inline javascript for enabling date 15 days from newDate

I am using air datepicker for a form element and want to set the calendar to show dates which are 15 days from the current date and disabling selection of all previous dates.
However, I haven't been able to find a solution to this.
The following is the input field code so far:
<input type="text" data-date-format="dd-mm-yyyy" data-range="true" data-multiple-dates-separator=" - " data-language="en" data-startDate= newDate(+new Date + 12096e5) class="datepicker-here" name="Schedule">
Any help will be really appreciated.

Using jQuery UI
var dateToday = new Date();
var dates = $("#date").datepicker({
defaultDate: "+15",
changeMonth: true,
minDate: "+15",
onSelect: function(selectedDate) {
var option = this.id == "from" ? "minDate" : "maxDate",
instance = $(this).data("datepicker"),
date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
dates.not(this).datepicker("option", option, date);
}
});

Using air Datepicker
set minDate while initializing datepicker
var dateToday = new Date();
var dates = $("#date").datepicker({
language: 'en',
minDate: getMinDate(15)
});
function getMinDate(days) {
var date = new Date();
date.setDate(date.getDate() + days);
return date;
}
