disable past dates on datepicker

Question

How to disable past dates from the current date on a datetimepicker? I tried few posts for similar question but was unable to achieve it, Below is what I tried

Answer 1

If you want to set date on page load then use this:

 $('#datetimepicker1').datetimepicker({
  minDate: new Date()
  });

This will set today's date as start date on page load itself and disable all the previous dates.
But if you want to set date on click of particular text-box instead of setting it on page load then use this: $('#datetimepicker1').datetimepicker(); $("#datetimepicker1").on("click", function (e) { $('#datetimepicker1').data("DateTimePicker").minDate(new Date()); });

In place of new Date(), we can use any string specifying Date in a format specified by us if we don't want to set current date as minimum date. e.g:

$('#datetimepicker1').data("DateTimePicker").minDate("10/15/2018");
