javascript - Bootstrap 3 datetimepicker events not firing up

Question

I am using Bootstrap 3 DateTimePicker and I am trying example 8 (Linked datetimepicker).

$('#dpStart').datetimepicker({
  pickDate: true, //en/disables the date picker
  pickTime: false,
  format: "DD-MM-YYYY",
  useMinutes: false, //en/disables the minutes picker
  useSeconds: false
});

$('#dpEnd').datetimepicker({
  pickDate: true, //en/disables the date picker
  pickTime: false,
  format: "DD-MM-YYYY",
  useMinutes: false, //en/disables the minutes picker
  useSeconds: false
});

$("#dpStart").on("dp.change", function(e) {
  alert('hey');
  $('#dpEnd').data("DateTimePicker").setMinDate(e.date);
});

$("#dpEnd").on("dp.change", function(e) {
  $('#dpStart').data("DateTimePicker").setMaxDate(e.date);
});

Answer 1

This may seem silly, but did you check you're using the same bootstrap-datetimepicker.js plugin that you're referring to in your question?

There are two versions I know of which are very similar:

1. The version you provided in your question: http://eonasdan.github.io/bootstrap-datetimepicker/
2. A slightly different version: http://www.eyecon.ro/bootstrap-datepicker/

The first version responds to change.dp, while the second version responds to dp.change.

Just check the comments at the top of the bootstrap-datetimepicker.js to see which one you're using.
