how to add a day to a date using jquery datepicker

I have 2 textboxes on my site for pickup date and drop off date both using the jquery date picker.

I am having trouble setting the drop off date value to be one day ahead of the pickup date that was selected.

Here is what I have:

$('.pickupDate').change(function() {
    var date2 = $('.pic开发者_运维知识库kupDate').datepicker('getDate', '+1d'); 
    $('.dropoffDate').datepicker('setDate', date2);
});

The above will execute but the value in the drop off textbox will match the pickup value instead of being one day ahead. eg: if I select 01-01-2010 the above code returns 01-01-2010 in the drop off box instead of 02-01-2010.

Any thoughts?

Thanks for your help, Rich

Try this:

 $('.pickupDate').change(function() {
  var date2 = $('.pickupDate').datepicker('getDate', '+1d'); 
  date2.setDate(date2.getDate()+1); 
  $('.dropoffDate').datepicker('setDate', date2);
});

This answer really helped me get started (noob) - but I encountered some weird behavior when I set a start date of 12/31/2014 and added +1 to default the end date. Instead of giving me an end date of 01/01/2015 I was getting 02/01/2015 (!!!). This version parses the components of the start date to avoid these end of year oddities.

 $( "#date_start" ).datepicker({

   minDate: 0,
   dateFormat: "mm/dd/yy",

   onSelect: function(selected) {
         $("#date_end").datepicker("option","minDate", selected); //  mindate on the End datepicker cannot be less than start date already selected.
         var date = $(this).datepicker('getDate');
         var tempStartDate = new Date(date);
         var default_end = new Date(tempStartDate.getFullYear(), tempStartDate.getMonth(), tempStartDate.getDate()+1); //this parses date to overcome new year date weirdness
         $('#date_end').datepicker('setDate', default_end); // Set as default                           
   }

 });

 $( "#date_end" ).datepicker({

   minDate: 0,
   dateFormat: "mm/dd/yy",

   onSelect: function(selected) {
     $("#date_start").datepicker("option","maxDate", selected); //  maxdate on the Start datepicker cannot be more than end date selected.

  }

});

The datepicker('setDate') sets the date in the datepicket not in the input.

You should add the date and set it in the input.

var date2 = $('.pickupDate').datepicker('getDate');
var nextDayDate = new Date();
nextDayDate.setDate(date2.getDate() + 1);
$('input').val(nextDayDate);

var today = new Date();
date = today.getDate() >= 10 ? `${today.getDate()}` : `0${today.getDate()}`;
month = today.getMonth()+1 >= 10 ? `${today.getMonth()+1}` : `0${today.getMonth()+1}`;
year = `${today.getFullYear()}`;
$('#datepicker_input_id').attr('value', `${month}/${date}/${year}`);
