javascript - 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 ?

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("-");
    }
}
