[javascript] Get the value of bootstrap Datetimepicker in JavaScript

I need to get the value of Datetimepicker in my JavaScript function. I have made something like this, but it doesn't work:

$("#date").click( function(){
    alert(document.getElementById('datetimepicker1').value);
});

It gives me 'undefined'

This is working for me using this Bootsrap Datetimepiker, it returns the value as it is shown in the datepicker input, e.g. 2019-04-11

$('#myDateTimePicker').on('click,focusout', function (){
    var myDate = $("#myDateTimePicker").val();
    //console.log(myDate);
    //alert(myDate);
});

It seems the doc evolved.

One should now use : $("#datetimepicker1").data("DateTimePicker").date().

NB : Doing so return a Moment object, not a Date object

I'm using the latest Bootstrap 3 DateTime Picker (http://eonasdan.github.io/bootstrap-datetimepicker/)

This is how you should use DateTime Picker inline:

var selectedDate = $("#datetimepicker").find(".active").data("day");

The above returned: 03/23/2017

Or try:

$("#datetimepicker").data().date;

To call the Bootstrap-datetimepikcer supported functions, you should use the syntax:

$('#datetimepicker').data("DateTimePicker").FUNCTION()

So you can try the function:

$('#datetimepicker').data("DateTimePicker").date();

Documentation: http://eonasdan.github.io/bootstrap-datetimepicker/Functions/

Since the return value has changed, $("#datetimepicker1").data("DateTimePicker").date() actually returns a moment object as Alexandre Bourlier stated:

NB : Doing so return a Moment object, not a Date object

Therefore, we must use .toDate() to change this statement to a date as such:

$("#datetimepicker1").data("DateTimePicker").date().toDate();

I tried all the above methods and I did not get the value properly in the same format, then I found this.

$("#datetimepicker1").find("input")[1].value;

The above code will return the value in the same format as in the datetime picker.

This may help you guys in the future.

Hope this was helpful..
