Disabling 180 days after the current date in Boots

问题:

Working on a form whereby am using bootstrap datepicker to display dates to the user. There are 2 input fields to show the dates mainly departure date and return date.

When the user selects a departure date (on the datepicker),, I want to capture the date selected and on the return date field disable 180 days after the departure date selected.

~ Please assist?

Departure date and return date

 <!-- Departure date-->
<div class="form-line registar2 love {{ $errors->has('departure_date') ? ' has-error' : '' }}">
    <input type="text" placeholder="Departure Date*" class="form-input dateTextBox" name="departure_date" id="departureDate" value="{{ old('departure_date') }}" required>
</div>
<!--End departure-->

<!-- Return date-->
<div class="form-line registar2 move {{ $errors->has('return_date') ? ' has-error' : '' }}">
         <input type="text" placeholder="Return Date*" class="form-input dateTextBox" name="return_date" id="returnDate" value="{{ old('return_date') }}" required>
</div>
<!-- End return date--> 

Javascript logic for the datepicker

 //Departure date
     $( function() {
      $( "#departureDate" ).datepicker({
        changeMonth: true,
        changeYear: true,
        //yy-mm-dd
        dateFormat: 'yy-mm-dd',
        minDate: '0',
        maxDate: "+20Y",
      });
    });

    //return date
    $( function() {
      $( "#returnDate" ).datepicker({
        changeMonth: true,
        changeYear: true,
        //yy-mm-dd
        dateFormat: 'yy-mm-dd',
        minDate: '0',
        maxDate: "+180D",
      });
    });
    //End dob

You have to use moment.js to calculate date in JavaScript. Refer the code to set another date picker according to the selected picker date.

$("#ret").hide();

$("#dep").datepicker({
    dateFormat: 'dd/mm/yy',
    minDate: 0,
    onSelect: function(dateText) {

        $("#ret").show();
        $("#ret").val('');

        var maxDate = moment(dateText, "DD/MM/YYYY").add(180, 'days').format("DD/MM/YYYY");

        $("#ret").datepicker('option', 'maxDate', maxDate);
        $("#ret").datepicker('option', 'minDate', dateText);

    }
});

$("#ret").datepicker({
    dateFormat: 'dd/mm/yy'
});

<p>Departure Date: <input type="text" id="dep" /></p>
<p>Return Date: <input type="text" id="ret" /></p>

Try this...

 $( function() {
  $( "#departureDate" ).datepicker({
    changeMonth: true,
    changeYear: true,
    //yy-mm-dd
    dateFormat: 'yy-mm-dd',
    minDate: '0',
    maxDate: "+20Y",
      }).on('changeDate', function (selected) {
        var minDate=new Date(selected.date.getFullYear(),selected.date.getMonth(),selected.date.getDate()+180)

        $('#returnDate').datepicker('setStartDate', minDate);
     });

  });

 $( function() {
      $( "#returnDate" ).datepicker({
        changeMonth: true,
        changeYear: true,
        //yy-mm-dd
        dateFormat: 'yy-mm-dd',
        minDate: '0',
        maxDate: "+180D",
      });
    });
