Question

I have two datePickers in the same page and I wanna change the second datepicker’s minDate depending the first one. Here is my code:

$("#datepickerDepart" ).datepicker({
        dateFormat: "mm-dd-yy", 
                minDate: 0,
        onSelect: function(dateText, inst) {
          var m = dateText.substring(0,2);
          var d = dateText.substring(3,5);
          var y = dateText.substring(6,10);
          console.log(d);
          console.log(m);
          console.log(y);
          var newDate = new Date(y,m-1,d);
          console.log(newDate);
          $('#datepickerReturn').val("");
                      $('#datepickerReturn').datepicker({
              dateFormat: "mm-dd-yy",
              minDate: newDate
          })
             }
});

But I have a question, the first time I select a date in the first datePicker, the minDate of second one will be set according to this, but when I reselect the first one, the second datePicker’s minDate won’t change anymore, it will remain. I don’t know why. Please help!!

I just wanna the minDate of the second one will change as long as the selected date of the first one change.

$("#strStartDate").datepicker({ 
  dateFormat: 'dd/mm/yy', 
  constrainInput: true,
  firstDay: 1,
  hideIfNoPrevNext: true,
  onSelect: function(){
        if ($("#strStartDate").val() > $("#strEndDate").val()){
            $("#strEndDate").val($("#strStartDate").val());
        }
  }

});

$("#strEndDate").datepicker({ 
  dateFormat: 'dd/mm/yy', 
  constrainInput: true,
  firstDay: 1,
  hideIfNoPrevNext: true,
  beforeShow: function (input, inst) {
        inst.settings.minDate = $("#strStartDate").val();
 }

});
