Bootstrap datepicker - Display in M YYYY, Send data to server in MMYYYY format

Using bootstrap datepicker to pick a date. Everything works fine as expected. But, because of server restriction we need to send data on submit like "022021" instead of "Feb 2021" now.
Not sure how to send data after formatting from original? Can help to provide any documentation or hints?
Thanks
$.fn.datepicker.defaults.format = 'M yyyy';
$('[data-key="from_date"]').datepicker({
format: 'M yyyy',
viewMode: 'months',
minViewMode: 'months',
autoclose: true,
todayHighlight: true,
endDate: new Date()
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input name="from_date" data-key='from_date' />
<input type="submit" class="submit-date">

I test it in Fiddle.
Bootstrap v4.5.2
Datepicker for Bootstrap v1.9.0
This code should work.
<input type="text" class="form-control" id="date">
And this is the simple Javascript
$('#date').datepicker({
format: 'mmyyyy',
});
The result is
022021

Here you can set 2 formats 1 for display and 1 for getting data from backend.
$('.datepicker').datepicker({
format: {
toDisplay: function (date, format, language) {
var d = new Date(date);
d.setDate(d.getDate() - 7);
return d.toISOString();
},
toValue: function (date, format, language) {
var d = new Date(date);
d.setDate(d.getDate() + 7);
return new Date(d);
}
},
autoclose: true
});

Datepicker should be close after selecting a Date

I am using Two types of datepicker in my page in one field I am using jQuery Multidatepicker and on another input field I am using datepicker. Both are working fine but the problem is datepicker is not hiding after selecting a date.
HTML
<div>
<label>Start Date:</label> <br />
<s:textfield type="text" readonly="true" id="startDate" name="startDate"
class="form-control" autocomplete="off"/>
</div>
JAVASCRIPT
In below code I used autoclose: true, but not working.
$("#startDate").datepicker({
prevText : "click for previous months",
nextText : "click for next months",
showOtherMonths : true,
dateFormat : 'dd/mm/yy',
selectOtherMonths : false,
maxDate : new Date(),
autoclose: true
});
In below code I used autoHide: true, still not working
$("#startDate").datepicker({
prevText : "click for previous months",
nextText : "click for next months",
showOtherMonths : true,
dateFormat : 'dd/mm/yy',
selectOtherMonths : false,
maxDate : new Date(),
autoHide: true
});
I wants to close calendar after selecting date automatically.
Please tell me what is the problem.

Check this code:
$(document).ready(function () {
$('#startDate').datepicker({
prevText : "click for previous months",
nextText : "click for next months",
showOtherMonths : true,
dateFormat : 'dd/mm/yy',
selectOtherMonths : false,
maxDate : new Date()
}).on('change', function(){
$('.datepicker').hide();
});
});

The datepicker should be closed automatically after user picking a date.
I think maybe the bug is caused by some where else in your code,
or you can simply try this first
$("#startDate").datepicker({});

How to have a dynamic maximum end date in Bootstrap Date Picker

I am using the following date picker on my website for a start and end date selection:
https://bootstrap-datepicker.readthedocs.org/en/latest/index.html
The rules are:
start date can be between today and + 30 days, no more
end date can be no more than 1 year after the selected start date
So when the form loads, I've set the endDate option to "+1y -1d" which works great. But if the customer picks a start date of +30 days for example, I need the endDate option on the second field to extend to "current start date +1y -1d" again.
I've started the code but really not sure how to acheive this:
<script type="text/javascript">
$(function() {
$(".startdate").datepicker({
format: 'd MM yyyy',
startDate: '+0d',
endDate: '+30d',
autoclose: true,
startView: 0,
minViewMode: 0,
todayHighlight: true,
orientation: "top"
});
$(".enddate").datepicker({
format: 'd MM yyyy',
startDate: '+1d',
endDate: '+1y -1d',
autoclose: true,
startView: 0,
minViewMode: 0,
todayHighlight: true,
orientation: "top"
});
$("#startdate").change(function() {
var startdate = new Date ( $("#startdate").val() ) ;
//alert(startdate);
var newendatemaximum;
$(".enddate").datepicker({
endDate: ???????
});
});
});
</script>
Work In Progress Solution:
$(".startdate").change(function() {
//alert("start date change");
var newendatemaximum = new Date ( $(".startdate").val() ) ;
newendatemaximum.setYear(newendatemaximum.getFullYear() + 1);
alert(newendatemaximum);
$(".enddate").datepicker("option", "endDate", newendatemaximum);
});

You don't have to use json to set datepicker options. You can set them directly. Once you have the new max date that you want to use as a javascript date, you can just set that option directly:
$("#startdate").change(function() {
var newendatemaximum = new Date ( $("#startdate").val() ) ;
newendatemaximum.setYear(newendatemaximum.getFullYear() + 1);
$(".enddate").datepicker("option", "endDate", newendatemaximum);
});

Put age restriction of 18 years - Bootstrap Datepicker

I am using Bootstrap Datepicker.
I want to put an Age Restriction of 18 Years.
Dates less than Age 18 Years from current date should be disabled.
Here is my Fiddle:
http://jsfiddle.net/kGGCZ/17/
JS:
$(function()
{
$('#datepicker').datepicker(
{
viewMode: "years",
defaultDate: '-2yr',
}
);
});

Simply put endDate: '-18y' if you only want to allow user whose age is 18 years and above.
<input type="text" class="datepicker">
<script>
$('.datepicker').datepicker({
endDate: '-18y'
});
</script>
Working Example: https://jsfiddle.net/sparshturkane/w46euf5q/1/
Please refer Bootstrap Date picker docs for more options and instructions

This is the JavaScript you are after:
var dt = new Date();
dt.setFullYear(new Date().getFullYear()-18);
$('#datepicker').datepicker(
{
viewMode: "years",
endDate : dt
}
);
But your fiddle is using coffeescript so here is the same in coffee:
dt = new Date()
dt.setFullYear new Date().getFullYear() - 18
$("#datepicker").datepicker
viewMode: "years"
endDate: dt
working example: http://jsfiddle.net/Ln5x6/1/

You can use yearRange, to let users choose only years which comes under 18+ from current year. Like,
jQuery('#dateob').datepicker({
changeMonth: true,
changeYear: true,
yearRange: '-110:-18',
showButtonPanel: true
});

datetimepicker and dateFormat: unexpected format

I would like the date in the following format:
yyyy-mm-dd HH:mm:ss (2013-02-01 12:12:12)
This is how I'm trying:
$('#start_date,#end_date, #date').datetimepicker({
dateFormat: 'yyyy-mm-dd',
timeFormat: 'HH:mm:ss',
onSelect: function(value){
alert(value);
}
});
The problem is that onSelect i get: yyyyyyyy-mm-dd HH:mm:ss (20132013-02-01 12:12:12)
what am I doing wrong?

Try the following
dateFormat: 'yy-mm-dd',
