Detect change to selected date with bootstrap-datepicker

Try this:

$("#dp3").on("dp.change", function(e) {
    alert('hey');
});

Here is my code for that:

$('#date-daily').datepicker().on('changeDate', function(e) {
    //$('#other-input').val(e.format(0,"dd/mm/yyyy"));
    //alert(e.date);
    //alert(e.format(0,"dd/mm/yyyy"));
    //console.log(e.date); 
});

Just uncomment the one you prefer. The first option changes the value of other input element. The second one alerts the date with datepicker default format. The third one alerts the date with your own custom format. The last option outputs to log (default format date).

It's your choice to use the e.date , e.dates (for múltiple date input) or e.format(...).

All others answers are related to jQuery UI datepicker, but the question is about bootstrap-datepicker.

You can use the on changeDate event to trigger a change event on the related input, and then handle both ways of changing the date from the onChange handler:

changeDate

Fired when the date is changed.

Example:

$('#dp3').datepicker().on('changeDate', function (ev) {
    $('#date-daily').change();
});
$('#date-daily').val('0000-00-00');
$('#date-daily').change(function () {
    console.log($('#date-daily').val());
});
