Disabled past months in monthpicker

I have a monthpicker something like datepicker and I want to disable past days or I have reserved day and and I want to give them to class.
My codes are below but I guess related code is this
$('#monthpicker').monthpicker().on('monthpicker-change-year', function(e, year) {
$('#monthpicker').monthpicker('disableMonths', [1, 2, 3, 4]); // (re)enables all
if (year === '2017') {
$('#monthpicker').monthpicker('disableMonths', [1, 2, 3, 4]);
}
if (year === '2019') {
$('#monthpicker').monthpicker('disableMonths', [9, 10, 11, 12]);
}
});
and this is the all code
(function($) {
var methods = {
init: function(options) {
return this.each(function() {
var
$this = $(this),

Javascript Datepicker - disabling future dates

Just a little bit of a disclaimer: I'm pretty much a noob at JavaScript and followed a bit of a guide for my datepicker. Please go easy on me.
I have developed a form (with my knowledge) and I have implemented a custom developed JavaScript datepicker for my 'date of incident' field.
For this field I have gotten the date to work but I need to code the datepicker so that the user cannot select any date after the currant date, only previous dates before the currant date and should also accept the currant date.
I am thinking if I could use 'minDate' or 'maxDate'? (If that's possible without jQuery)
Please note I am only using JavaScript and not jQuery or Bootstrap.
Here is the HTML and JavaScript for my datepicker code, I am not sure whether to create a new function or implement it in my currant one (It's a lot of code)
HTML:
<label>Date of Incident:</label><input id="datepick" placeholder="Enter the date of incident" type="text"/>
Javascript:

Custom function be called instead of getfullyear() in java script

I want my custom function be called instead of getfullyear() in java script how can I do this ? The point is to change a gregorian calendar to jallali in jomsocial.
for example when I write this
d=new Date(b.year,b.month,b.date+a);c.set("highlight",JalaliDate[d.getFullYear(),d.getMonth(),d.getDate()]
The result will be 2014/16/7, I want it to became 1393/6/25

jQuery Datepicker close datepicker after selected date

HTML:
<div class="container">
<div class="hero-unit">
<input type="text" placeholder="click to show datepicker" id="example1">
</div>
</div>
jQuery:
<script type="text/javascript">
$(document).ready(function () {
$('#example1').datepicker({
format: "dd/mm/yyyy"
});
});
</script>
I use bootstrap datepicker.
When I click to datepicker it opens and I select any date.
My question:
If I choose date from datepicker, I want to close datepicker popup.
Which event do i need to use in order to close datepicker on select date?
Edited:
I have found a solution
This works
$(document).mouseup(function (e) {
$('#example1').Close();
});
But this below does not work why ?
$('#example1').datepicker().on('changeDate', function (ev) {
$('#example1').Close();
});

Actually you don't need to replace this all (#Ben Rhouma Zied answere)....
There are 2 ways to do this. One is to use autoclose property, the other (alternativ) way is to use the on change property thats fired by the input when selecting a Date.
HTML
<div class="container">
<div class="hero-unit">
<input type="text" placeholder="Sample 1: Click to show datepicker" id="example1">
</div>
<div class="hero-unit">
<input type="text" placeholder="Sample 2: Click to show datepicker" id="example2">
</div>
</div>
jQuery
$(document).ready(function () {
$('#example1').datepicker({
format: "dd/mm/yyyy",
autoclose: true
});
//Alternativ way
$('#example2').datepicker({
format: "dd/mm/yyyy"
}).on('change', function(){
$('.datepicker').hide();
});
});
this is all you have to do :)
HERE IS A FIDDLE to see whats happening.
Fiddleupdate on 13 of July 2016: CDN wasnt present anymore
According to your EDIT:
$('#example1').datepicker().on('changeDate', function (ev) {
$('#example1').Close();
});
Here you take the Input (that has no Close-Function) and create a Datepicker-Element. If the element changes you want to close it but you still try to close the Input (That has no close-function).
Binding a mouseup event to the document state may not be the best idea because you will fire all containing scripts on each click!
Thats it :)
EDIT: August 2017 (Added a StackOverFlowFiddle aka Snippet. Same as in Top of Post)
$(document).ready(function () {
$('#example1').datepicker({
format: "dd/mm/yyyy",
autoclose: true
});
//Alternativ way
$('#example2').datepicker({
format: "dd/mm/yyyy"
}).on('change', function(){
$('.datepicker').hide();
});
});
.hero-unit{
float: left;
width: 210px;
margin-right: 25px;
}
.hero-unit input{
width: 100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

</div>
<div class="hero-unit">
<input type="text" placeholder="Sample 2: Click to show datepicker" id="example2">
</div>
</div>
EDIT: December 2018 Obviously Bootstrap-Datepicker doesnt work with jQuery 3.x see this to fix

This is my edited version : you just need to add an extra argument "autoClose".
example :
$('input[name="fieldName"]').datepicker({ autoClose: true});
also you can specify a close callback if you want. :)
replace datepicker.js with this:
!function( $ ) {
// Picker object
var Datepicker = function(element, options , closeCallBack){
this.element = $(element);
this.format = DPGlobal.parseFormat(options.format||this.element.data('date-format')||'dd/mm/yyyy');
this.autoClose = options.autoClose||this.element.data('date-autoClose')|| true;
this.closeCallback = closeCallBack || function(){};
this.picker = $(DPGlobal.template)
.appendTo('body')
.on({
click: $.proxy(this.click, this)//,
//mousedown: $.proxy(this.mousedown, this)
});
this.isInput = this.element.is('input');
this.component = this.element.is('.date') ? this.element.find('.add-on') : false;
if (this.isInput) {
this.element.on({
focus: $.proxy(this.show, this),
//blur: $.proxy(this.hide, this),
keyup: $.proxy(this.update, this)
});
} else {
if (this.component){
this.component.on('click', $.proxy(this.show, this));
} else {
this.element.on('click', $.proxy(this.show, this));
}

There is another code that's works for me (jQuery).
$(".datepicker").datepicker({
format: "dd/mm/yyyy",
autoHide: true
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.css" />
Date: <input type="text" readonly="true" class="datepicker">

Answer above did not work for me on Chrome. The change event was been fired after I clicked out of the field somewhere, which did not help because the datepicker window is also closed too when you click out of the field.
I did use this code and it worked pretty well. You can place it after calling .datepicker();
HTML
<input type="text" class="datepicker-input" placeholder="click to show datepicker" />
JavaScript
$(".datepicker-input").each(function() {
$(this).datepicker();
});
$(".datepicker-input").click(function() {
$(".datepicker-days .day").click(function() {
$('.datepicker').hide();
});
});

Just add this option to Datepicker component:
forceParse: false
Example:
$('.datepicker').datepicker({
format: 'mm/dd/yyyy',
defaultDate: 'now',
forceParse: false,
endDate: "today"
});

In the above code do i want to add something more or want to change something..?
Please let me know..
Thanks in advance,
Sree ram.

The following code should prevent any dates prior to the current date from being selectable.
$('#element').datepicker({
minDate: new Date()
});
Hopefully this answers your question.
