bootstrap date picker - changing via javascript not syncing with Calender

I have a element I'm using as a datepicker:
I set it up using the following script:
$('#fltProdFromQuo').datepicker({
format: "dd M yyyy",
todayBtn: "linked",
autoclose: true,
todayHighlight: true
});
And set the value to 1st June 2020:
$('#fltProdFromQuo').val('2020-06-01') ;
WHich seems to work until I click the field, and the calander shows todays date:
Does anyone have any idea what I've missed to make the calendar show the correct date?
Thank you in advance of any help given.

Found the answer. I didn't know that once I set the date I had to "Update" it to change the calender, never had to do this before:
$('#fltProdFromQuo').val('2020-06-01') ;
$('#fltProdFromQuo').datepicker('update');
Working tickety boo now!

bootstrap date picker returns NaN undefined NaN on click

I'm using a bootstrap datepicker to input dates in a input/text element. It works fine if I click an actual date in the graphic calendar, but if I click in a whitespace area on the graphic, it returns a value of 'NaN Undefined NaN' in the input box.
<Input type='text' id='startDatePicker' class='watchlistDateInput' name='startDatePicker' placeholder='<%= data.SearchStart %'>
Here's the JavaScript setup for the datepicker:
// build start datepicker ui
var startPicker = $('#startDatePicker').datepicker({
showOn: 'button',
buttonImage: 'img/calendar-blu.png',
buttonImageOnly: true,
showOtherMonths: false,
selectOtherMonths: true,
changeMonth: true,
changeYear: true,
dateFormat: 'dd M yy'
});
Any thoughts on how to fix this problem, or similar questions, dealing with the calendar click, not just typing the date in the input field?
Thanks

How to validate to allow only current and next date in the date picker using javascript

I have two date pickers one to select the start date and the other for end date.Now I need to validate so that the user can only select current and next date from the date picker and not the other dates.How to validate using javascript

If its about jQuery UI Datepicker, you can provide date selection range as:
$( "#datepicker" ).datepicker({ minDate: 0, maxDate: "+1D" });
In this minDate : 0 represents Today and maxDate: +1D is Tomorrow
Here is Demo for your requirement.

Jquery date time picker with 2013-05-30 19:02:51.497 format

You can check it by using jquery-ui-datetimepicker-plugin
$('#startDate, #endDate')
.datetimepicker({ dateFormat: 'yy-mm-dd', timeFormat: 'hh:mm:ss' });

I have followed this
but did not work and working one is
$("#startDate, #endDate").datetimepicker({ dateFormat: 'dd-mm-yy hh:mm:ss'});

jQuery Date Picker Pick Year First and then Month

What changes are needed to show the Years dropdown first and then the months dropdown as second field in jQuery so users can select which year they are born and then select the month in that year. We still want to restrict that calendar cannot display date greater than today.
If user selects 2011, they should not be allowed to select date greater than today.

I was looking for this also and got here but no solution so I get into jquery-ui.custom.min.js and found the an option. Its as below. Hope it helps although its a bit late..
$( "#datepicker_id" ).datepicker({
showOn: "button",
buttonImage: "images/calendar.png",
buttonImageOnly: true,
dateFormat:'mm-dd-yy',
changeYear: true,
changeMonth: true,
showMonthAfterYear: true, //this is what you are looking for
maxDate:0
});
But if you found that already you should have posted it here :)

For this simple use below line:
startView: 2
And add below line to prevent to select date greater than today:
endDate: new Date(),
