Bootstrap DatePicker - Onchange

Question

I am using the Bootstrap 3 Datepicker plugin. When the user chooses a date, I want to update various parts of my UI. I'm basically trying to create a function that is called when the date changes. However, I've been unsuccessful in my attempts. Currently, I'm trying the following

$('#myDatePicker').datetimepicker({
  change: function() {
    alert('date has changed!');
  }                  
});

Unfortunately, the change function never fires. How do I call a function when the date is changed in the date picker?

Answer 1

You can try this:

$("#myDatePicker").datetimepicker().on('changeDate', function(e) {
    alert('date has changed!');
});

Bootstrap doc reference: changeDate

Answer 2

Bootstrap 4

The eonasdan datepicker plugin is no longer supported in Bootstrap 4, but there is a new plugin: https://tempusdominus.github.io/bootstrap-4

"Tempus Dominus is the successor to the very popular Eonasdan/bootstrap-datetimepicker"

To detect the change event, use:

$("#datetimepicker1").on("change.datetimepicker", function (e) {
    if (e.oldDate !== e.date) {
        alert('You picked: ' + new Date(e.date).toLocaleDateString('en-US'))
    }
})

Bootstrap 3 (original answer)

According to the docs, the event is dp.change:

$('#myDatePicker').datetimepicker().on('dp.change',function(e){
    console.log(e)
})

Answer 3

OnChange : Function(data)
{
valueAccessor()(data);
}

Answer 4

For the Bootstrap datepicker the event is changeDate in case people are looking for that: Docs

$("input[name='Date']").datepicker().on('changeDate', function (e) {
  console.log(e); //Where e contains date, dates and format
});
