Datepicker - 1

Answer 1

Set an onSelect handler to the first datepicker, within the handler update minDate option of the second datepicker. Where use getDate method to get the selected Date object.

$(function() {
  let $dt1 = $("#datepicker1").datepicker({
    minDate: 0,
    dateFormat: "yy-mm-dd",
    // attach handler
    onSelect: function(dateString, instance) {
      // update minDate option of second datepicker
      // create a Date instance using datepicker instance
      // where increment the day value
      // $dt2.datepicker('option', 'minDate', new Date(instance.selectedYear, instance.selectedMonth, ++instance.selectedDay));

      // or you can get Date from jQuery object
      // or get jquery instance from instance
      // like : instance.input or $("#datepicker1")

      let date = $dt1.datepicker('getDate');
      // or let date = instance.input.datepicker('getDate');

      // increment day
      date.setDate(date.getDate() + 1)

      $dt2.datepicker('option', 'minDate', date);
      // to set min date as datepickers 1 value simply use
      // $dt2.datepicker('option', 'minDate', dateString );

      // incrementing day from a customized data string is hard that's the reason for using datepicker instance
    }
  });

  // cache the reference of input element
  var $dt2 = $("#datepicker2").datepicker({
    dateFormat: "yy-mm-dd"
  });
});
