How to set max 9 days after datepicker 1 selected by Daterangepicker

Question

Hi i want to set default maxDate 9 days after I select input first. here is my code HTML

<input type="text" placeholder="Date" name="daterange" class="form-control date-picker form-date" id="date-picker" />
<input type="text" placeholder="Date" name="daterange" class="form-control date-picker-2 form-date" id="date date-picker-2"/>

and JS

  $('.date-picker').daterangepicker({
    singleDatePicker: true,
    showDropdowns: true,
    minDate: moment().subtract(1, 'years'),
    maxDate: moment().subtract(1, 'days'),
    locale: {
      format: 'DD-MM-YYYY'
    }
  }
var departpicker = $('.date-picker').val();
$('.date-picker-2').daterangepicker({
  minDate: departpicker,
  //here is the bug
  maxDate: moment().add(9, 'days')
});

In my mind is how to departpicker + 9 days. I try departpicker.add(9, 'days') doesnt work. Any body help? For example when I select 1 July 2018 on first input and maxDate on second input is 10 July 2018 my full code https://jsfiddle.net/dedi_wibisono17/Lmjv9hp2/7/ Thank you

Answer 1

You should specify the date format before adding 9 days.

$('.date-picker-2').daterangepicker({
  minDate: departpicker,
  //here is the bug
  maxDate: moment(departpicker, 'DD-MM-YYYY').add(9, 'days');
});

You can use the maxSpan option

"maxSpan": {
    "days": 9
},
