Setting selected date in calendar to null on Bootstrap datetime picker

I'm using the bootstrap datetime picker, the documentation of which can be found here: https://eonasdan.github.io/bootstrap-datetimepicker/Options/
I'm trying to set the selected date to null. I'm able to blank out the date (i.e. 2/10/2019) within the input field, but when I click on the input field and the calendar opens, the old date is still selected in blue. WiThis is my code to de-select all dates within the calendar.
$(document).ready(function() {
$('.removedate').on('click', function(){
$("#id_booking_date").val('') //this correctly removes date from input field
$('.input-group').datetimepicker({
date: new Date(null)
});
});
This code isn't working. Do you know what I should try?
Thanks!

Can you please try to use "useCurrent" option for this? Check it out here https://eonasdan.github.io/bootstrap-datetimepicker/Options/#usecurrent

Please try this, they have clearly mentioned here
Working example:
$('#datetimepicker4').datetimepicker({
useCurrent: false,//
});

Tempus Dominus - setting date with javascript

I am using Tempus Dominus Bootstrap-4 datetime picker in a modal window that is shown when user double clicks on a specific row of a table:
$('#btn_modal').on('click', function() {
//
// .... some irrelevenat code, like geting data of a specific row,
// .... filling other fields
//
$('#modal_datetimepicker').datetimepicker({
defaultDate: moment(row['date_rkw'], "YYYY-MM-DD"),
viewMode: 'days',
format: 'YYYY-MM-DD',
extraformats: [ 'YYYY-MM-DD' ]
});
$('#modal').modal();
});
The date is properly set first time the modal is shown, but next time the modal is shown (selecting other row to edit), it keeps the previous value,
completely ignoring the above call with new value to defaultDate.
What is the proper way to set datetimepicker to a specific date?
I tried calling destroy with
$('#modal_datetimepicker').datetimepicker('destroy')
or even
$('#modal_datetimepicker').val(row['date_rkw'])
but with no luck.

You can try destroying datepicker when modal is hidden
$('#modal').modal('show')
.on('hidden.bs.modal',function(){
$('#modal_datetimepicker').datetimepicker('destroy')
});
Have a look at this reference - https://getbootstrap.com/docs/4.0/components/modal/

Why Date picker clear my input and select after clicked?

I have a problem in datepicker. My form has input and select option. After click input datepicker, my input and select always reset to first load page. What is my problem?
$('.myClassDate').datepicker({
format: "yyyy-mm-dd",
todayBtn: 'linked',
todayHighlight : true,
autoclose: true
});

maybe button in your form has not type="button" and your page will reload after click button

Show Jquery Date time picker onclick

I am using a ASP.NET GRIDVIEW. The column I am interested in is the "CHECKED IN" column that contains a checkbox and a label.
Grid View Image
The grid can bring back many lines of data from the database:
Columns of grid
Here's what I need to do:
When the 'Checked IN' checkbox is clicked. I would like the DataTime picker to appear.
[Checkbox is checked and Datatime picker appears][3]
checked in Checkbox
2. When the user has selected a date and time, I would like the value to appear in the label next to the Checked in checkbox.
DateTime to show only when it has been selected.
[Label is updated][4]
Hope this makes sense?
The only issue is that the GridView creates itself dynamically.

Thanks for your message.
I did resolve this, however I slightly changed what I was doing.
Here's my code...
$(".CheckOut").each(function () {
$(this).datetimepicker({
dateFormat: 'dd/mm/yy',
onClose: function (selectedDateTime) {
return Validate(this, this.id);
}
});
});
This code is exactly what I needed for the date/time picker to work within a GridView.

Update bootstrap datetimepicker after every step/click

I'm using this extension of Bootstrap's datepicker. It works well enough, but I've come upon a usability issue - when selecting a date/time, the text field the datepicker is attached to does not update unless all the steps (year/month/day/hour/minute) are selected to the end. Clicking away from the datepicker before clicking all the steps yields no change to the date in the text field.
How do I make it so that when the user clicks away mid-selection (maybe because they just want to change the date, but find the already-present hour and minute to be acceptable), the text field is updated appropriately?
For example:
Initial date in field: 2015/10/10 10:00
Click on 2015/10/15 -> click away -> date in field: 2015/10/15 10:00
Is that even possible?

Check this updated fiddle - https://jsfiddle.net/4cqLcxcm/8/
Added on changeDay event on datepicker, which will trigger on change of date and set that value into input box.
Below is the code I have changed.
$(document).ready(function() {
var now = new Date();
$('#send-time').datetimepicker({
format: 'yyyy/mm/dd hh:ii',
startDate: now
})
.on('changeDay', function(ev){
$('#send-time').datetimepicker('update',ev.date);
});
console.log('test');
});
