bootstrap datepicker change date event doesnt fire up when manually editing dates or clearing date

Question

<script type="text/javascript">
    // When the document is ready
    $(document).ready(function () {
        $('.datepicker').datepicker({
            format: "yyyy-mm-dd",
        }).on('changeDate', function(ev){
            // do what you want here
            $(this).datepicker('hide');
        }).on('changeDate', function(ev){
            if ($('#startdate').val() != '' && $('#enddate').val() != ''){
                $('#period').text(diffInDays() + ' d.'); 
            } else {
                $('#period').text("-");
            }
        });
    });
</script>

So here's what my datepicker looks like. So basically when I change date by clicking mouse it works good, however when I manually change date with keyboard or manually clear the date change date event doesn't get called. Is this a bug or am I doing something wrong here ?

Answer 1

You have to use the change event on the input itself if you want to respond to manual input, because the changeDate event is only for when the date is changed using the datepicker.

Try something like this:

$(document).ready(function() {
    $('.datepicker').datepicker({
        format: "yyyy-mm-dd",
    })
    //Listen for the change even on the input
    .change(dateChanged)
    .on('changeDate', dateChanged);
});

function dateChanged(ev) {
    $(this).datepicker('hide');
    if ($('#startdate').val() != '' && $('#enddate').val() != '') {
        $('#period').text(diffInDays() + ' d.');
    } else {
        $('#period').text("-");
    }
}

Could you give me an example ? – Marceline

.change(...).on('changeDate') causing double firing. – Jerrylee

Instead of 'changeDate' try 'dp.change' that worked for me – Oyer

I have value for input datepicker e.g 08-16-2017. When page is refreshed the value 08-16-2017 is assigned to input field. Is it possible to trigger changeDate via code after assigning value. – Rozanna

I had to add a keydown event to check for the tab key in IE. I found the delete and enter keys triggered the change, but the tab key did not. – Logos

In version 2.1.5

• bootstrap-datetimepicker.js
• http://www.eyecon.ro/bootstrap-datepicker
• Contributions:
• Andrew Rowls
• Thiago de Arruda
• updated for Bootstrap v3 by Jonathan Peterson @Eonasdan

changeDate has been renamed to change.dp so changedate was not working for me

$("#datetimepicker").datetimepicker().on('change.dp', function (e) {
            FillDate(new Date());
    });

also needed to change css class from datepicker to datepicker-input

<div id='datetimepicker' class='datepicker-input input-group controls'>
   <input id='txtStartDate' class='form-control' placeholder='Select datepicker' data-rule-required='true' data-format='MM-DD-YYYY' type='text' />
   <span class='input-group-addon'>
       <span class='icon-calendar' data-time-icon='icon-time' data-date-icon='icon-calendar'></span>
   </span>
</div>

Date formate also works in capitals like this data-format='MM-DD-YYYY'

it might be helpful for someone it gave me really hard time :)

As of version 4.7.14, the correct event reference is "dp.change" – Ostap

Answer 3

The new version has changed.. for the latest version use the code below:

$('#UpToDate').datetimepicker({
        format:'MMMM DD, YYYY',
        maxDate:moment(),
        defaultDate:moment()            
    }).on('dp.change',function(e){
        console.log(e);
    });

Answer 5

I found a short solution for it. No extra code is needed just trigger the changeDate event. E.g. $('.datepicker').datepicker().trigger('changeDate');

Answer 6

Try with below code sample.it is working for me

var date_input_field = $('input[name="date"]');
    date_input_field .datepicker({
        dateFormat: '/dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
    }).on('change', function(selected){
        alert("startDate..."+selected.timeStamp);
    });

Answer 7

This should make it work in both cases

function onDateChange() {
   // Do something here
}

$('#dpd1').bind('changeDate', onDateChange);
$('#dpd1').bind('input', onDateChange);

Depending which date picker for Bootstrap you're using, this is a known bug currently with this one:

Code: https://github.com/uxsolutions/bootstrap-datepicker

(Docs: https://bootstrap-datepicker.readthedocs.io/en/latest/)

Here's a bug report:

If anyone has a solution/workaround for this one, would be great if you'd include it.

I have this version about datetimepicker https://tempusdominus.github.io/bootstrap-4/ and for any reason doesn`t work the change event with jquery but with JS vanilla it does

I figure out like this

document.getElementById('date').onchange = function(){ ...the jquery code...}

I hope work for you

I was using AngularJS and AngularStrap 2.3.7 and trying to catch the 'change' event by listening to a <form> element (not the input itself) and none of the answers here worked for me. I tried to do:

$(form).on('change change.dp dp.change changeDate' function () {...})

And nothing would fire. I ended up listening to the focus and blur events and setting a custom property before/after on the element itself:

// special hack to make bs-datepickers fire change events
// use timeout to make sure they all exist first
$timeout(function () {  
    $('input[bs-datepicker]').on('focus', function (e){
        e.currentTarget.focusValue = e.currentTarget.value;
    });        
    $('input[bs-datepicker]').on('blur', function (e){
        if (e.currentTarget.focusValue !== e.currentTarget.value) {
            var event = new Event('change', { bubbles: true });
            e.currentTarget.dispatchEvent(event);
        }
    });
})

This basically manually checks the value before and after the focus and blur and dispatches a new 'change' event. The { bubbles: true } bit is what got the form to detect the change. If you have any datepicker elements inside of an ng-if you'll need to wrap the listeners in a $timeout to make sure the digest happens first so all of your datepicker elements exist.

Hope this helps someone!

if($('.single_datetime').length){
        $('.single_datetime').dateRangePicker({ format: 'DD.MM.YYYY HH:mm', language: 'tr', autoClose: true, singleDate : true, showShortcuts: false, time: {enabled: true}
        }).bind('datepicker-change',function(event,obj){caclDay();});
