Amsul DateTimePicker - How to unselect active date?

I am using amsul DateTime picker (https://amsul.ca/pickadate.js/date/) where if you see in the preview the today's date is highlighted in green. Now if you move the calendar to the next month or previous month. Every month's today's date is also highlighted.
How do I unhighlight any other dates then today's date?
$('.datepicker').pickadate()

I ran into this issue as well. As a workaround, I remove the
picker__day--highlighted class from every div with that class that
doesn't have today's timestamp as data-pick value:
var now = new Date();
var timestamp = new Date(now.getFullYear(), now.getMonth(), now.getDate()) / 1;
$('.datepicker').pickadate({
onRender: function() {
$('div.picker__day--highlighted').each(function(index, value) {
if ($(this).data('pick') !== timestamp) {
$(this).removeClass('picker__day--highlighted');
}
});
}
});

Display specific dates in bootstrap datepicker

I'm using bootstrap date picker in my project. It's a session booking project. From the admin panel, I add the sessions for specific dates and I want the user's of my website to be able to see the dates for which I have added a session. My frontend receives the data from database. The data contains all the dates for which I have added a session. I want my datepicker to display only these dates from the data and disable the other dates.
Currently I have temporarily used a select box to solve this issue. But a datepicker would be better as it looks good is easy to navigate.
See the picture below. This is how I have used a select box to temporarily solve the problem
Here is the desired output that I want
It should be a datepicker with only those dates enabled which I receive from the database. The other dates should be disabled
I tried searching it on google but I'm not able to find the solution. Is this possible using bootstrap date picker? If yes, please suggest a workaround.

You can use beforeShowDay function to enable only the dates returned from your back end system.
Documentation here
This function is executed for every date, it checks if it is present in the list of applicable dates, returns true if present and enables it, else returns false and disables it.
$(function () {
let enabledDates = ['2018-10-03', '2018-10-04', '2018-10-05', '2018-10-06', '2018-10-07', '2018-10-08'];
$('#datepicker').datepicker({
format: 'yyyy-mm-dd',
beforeShowDay: function (date) {
let fullDate = date.getFullYear() + '-' + (date.getMonth() + 1) + '-' + date.getDate();
return enabledDates.indexOf(fullDate) != -1
}
});
});
beforeShowDay function also allows you to return classes for custom styling
beforeShowDay: function (date) {
let fullDate = date.getFullYear() + '-' + (date.getMonth() + 1) + '-' + date.getDate();
if (enabledDates.indexOf(fullDate) != -1) {
return {
classes: 'enabled',
tooltip: 'You can select this date'
};
} else
return false
}
.enabled {
background: #DCDCDC;
}

None of the other solutions worked for me so here is my solution.
The documentation is not so clear and lacks of example but you can see a function that takes a date as a parameter and returns a Boolean, indicating whether or not this date is selectable
In this snippet, look at January 2020 for example in order to see only the active dates.
$(document).ready(function() {
var datesEnabled = [
'2021-01-01', '2021-01-11', '2021-01-21',
'2021-02-01', '2021-02-11', '2021-02-21',
'2021-03-01', '2021-03-11', '2021-03-21',
'2021-04-01', '2021-04-11', '2021-04-21',
'2021-05-01', '2021-05-11', '2021-05-21'
];
$("#datepicker-lorem").datepicker({
language: "fr",
autoclose: true,
todayHighlight: true,
todayBtn: true,
title: 'Test ;-)',
weekStart: 1,
format: 'dd/mm/yyyy',
// On n'active que les dates possibles
beforeShowDay: function(date) {
var allDates = date.getFullYear() + "-" + ('0' + (date.getMonth() + 1)).slice(-2) + "-" + ('0' + date.getDate()).slice(-2);
if (datesEnabled.indexOf(allDates) != -1) {
return {
classes: 'date-possible',
tooltip: 'Vous pouvez choisir cette date'
}
} else {
return false;
}
}
});
});
/* For better frontend result, add class to active date and add opacity to disabled date */
td.day.disabled {
opacity: 0.4;
}
td.date-possible {
background-color: red;
color: white;
}

jQuery - Get values from jQuery array got from field

First I have one field with daterangepicker.
I get value using $("#field").val().
I got like
{"start":"2018-03-23","end":"2018-03-29"}
But, I need start date and end date value from
{"start":"2018-03-23","end":"2018-03-29"}
My code is
<input id="field" type="text" value='' /><br/>
$(function() {
'use strict';
$("#field").daterangepicker({
dateFormat:'dd M',
datepickerOptions : {
numberOfMonths : 2
}
});
var curnt = moment().startOf('day').toDate();
var weeks = moment().subtract('days', 6).startOf('day').toDate();
$("#field").daterangepicker("setRange", {start: weeks, end: curnt});
});
function get_graph_data(){
var dates = JSON.parse($("#field").val());
console.log(dates.start);
console.log(dates.end);
var data = {
'action' : 'example_ajax_request',
'wp_graph': $("#field").val()
};
jQuery.post(ajax_url, data, function(response) {
alert('Got this from the server: ' + response);
});
}

What you get from the $("#field").val() is a JSON. You can easily do something like:
var dates = JSON.parse($("#field").val());
dates.start; // "2018-03-23"
dates.end; // "2018-03-29"
A snippet to help you:
$(function () {
var dates = JSON.parse($("#field").val());
console.log(dates.start); // "2018-03-23"
console.log(dates.end); // "2018-03-29"
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="field" type="hidden" value='{"start":"2018-03-23","end":"2018-03-29"}' />

You are using daterangepicker plugin so you should use it's methods instead of jQuery's val(). Select an input field and call data('daterangepicker'). Returned object contains startDate and endDate objects. Keep in mind that they are Date objects (not Strings), so you will need to format if you want to print them.
$('#field').daterangepicker({
locale: {
format: 'YYYY-MM-DD'
},
startDate: '2018-01-01',
endDate: '2018-12-31'
});
$("#getDateRange").click(function() {
var data = $("#field").data('daterangepicker');
var startDate = data.startDate.format('YYYY-MM-DD');
var endDate = data.endDate.format('YYYY-MM-DD');
alert('Start date: ' + startDate + ', end date: ' + endDate);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="//cdn.jsdelivr.net/momentjs/latest/moment.min.js"></script>
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/bootstrap/3/css/bootstrap.css" />
<script type="text/javascript" src="//cdn.jsdelivr.net/bootstrap.daterangepicker/2/daterangepicker.js"></script>
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/bootstrap.daterangepicker/2/daterangepicker.css" />
<input id="field" type="text" value='' />
<button type="button" id="getDateRange">Get start date</button>
It's always a good habit to check out official documentation of a plugin. You can check it out here.

unable to set calendar start date in pikaday calendar

When i trigger the start date input box, I want to show the future or past month in calendar popup as a starting date in end date calendar.

var picker = new Pikaday({

minDate: new Date(),
onSelect: function (date) {
picker2.setMinDate(date);
//picker2.???? to set the starting month of picker2 calendar
}
});
var picker2 = new Pikaday({

minDate: new Date(),
onSelect: function () {
console.log(this.getMoment().format('Do MMMM YYYY'));
}
});
</script>
</body>

please check the above example, based on start day selection i want to trigger the end date calendar starting month. please suggest.
JS bin link

As I understand your question, you want to set the selected month in picker to the picker2 object. use the API onOpen.
Example
var picker = new Pikaday({
field: document.getElementById('datepicker'),
format: 'D MMM YYYY',
minDate: new Date(),
onSelect: function(date) {
//console.log(this.getMoment().format('Do MMMM YYYY'));
console.log('test ' + date);
picker2.setMinDate(date);
//picker2.setStartRange(date)
}
});
var picker2 = new Pikaday({
field: document.getElementById('datepicker2'),
format: 'D MMM YYYY',
minDate: new Date(),
onOpen: function() {
picker2.gotoDate(picker.getDate())
},
onSelect: function() {
console.log(this.getMoment().format('Do MMMM YYYY'));
}
});

When I worked with Pikaday package in Vue.Js project I had to set default date to my date field in form. I tried many different versions of setting default date. But they didn't work for me. Finally I found the solution for my situation. The solution was to set prop like auto-default="autoDefault" here autoDefault is equels to true to Pikaday component like this...
<vue-pikaday v-model='date' auto-default="autoDefault" :options="pikadayOptions" />
data() {
return {
autoDefault : true,
pikadayOptions: {
format : 'YYYY/MM/DD',
minDate : moment().toDate(),
},
}
},

Disable some future dates in DateRangePicker

I'm trying to disable today date and 6 more days dates from today.
I know I can do that with maxDate but when I do, it disable all future dates.
My code:
$('input[name="datefilter"]').daterangepicker({
autoUpdateInput: false,
maxDate: new Date(),
"autoApply": true,
locale: {
"firstDay": 1,
"separator": " - "
}
});
I tried with maxDate: new Date(6) too but same error.
Any idea?

You can use the isInvalidDate function to return true/false if the date is valid or not:
invalid_dates = ['2017-01-11', '2017-01-12', '2017-01-13']
$(function() {
$('input[name="daterange"]').daterangepicker({
isInvalidDate: function(date)
{
return !!(invalid_dates.indexOf(date.format('YYYY-MM-DD')) > -1);
}
});
});

That's not an error, that's the expected behavior of the property you're using. You're telling it "don't allow any date beyond this". According to the docs, there is an option for isInvalidDate that Dekel found in his answer.
I was about to delete this answer, but decided against it due to pointing out that it wasn't an error, but the behavior of the property that was being used. Anyone should definitely upvote the other answer for finding that property first.
