jQuery UI Datepicker Problem with arrival - depart dates

Argh.. I am stumped....

I have a reservation module that is running the jQuery date-picker UI. I have an arrival date field and a departure date field each with a date-picker object initiated on both.

I want the default arrival date to be todays date I achieved this by doing the following:

   <script type="text/javascript">
      $(document).ready(function(){

          $(".arrive").datepicker();
          $(".depart").datepicker();

          $(".arrive").datepicker('setDate', new Date());

      });
   </script> 

That works perfectly however when a user selects an arrival date I then want the departure default date to be set as one day after the users selected arrival date. I tried using the onSelect events for the date-picker object and tried to pull the value from the arrival field and add a day but to no avail. I have seen this functionality before, I don't think it is very difficult I am just beyond stumped on this one. Any ideas? My html for the text fields is as follows:

<ul>
  <li>  
    <label>Arriving</label>     
    <span class="dateinput">                           开发者_高级运维                        
        <input class="arrive" type="text" value="" name="startDate" />                                  
        <img id="arrive"  src="images/calendar_icon.png"  />
        <div class="clear"></div>
    </span>
  </li>

  <li>  
    <label>Departing</label>        
    <span class="dateinput">                                
        <input class="depart" name="endDate" value="" type="text"  />               
        <img src="images/calendar_icon.png" />
        <div class="clear"></div>
    </span> 
  </li>
</ul>

Thanks a bunch to whoever can help me with this issue.

Using the documentation as inspiration:

<script type="text/javascript">
  $(document).ready(function(){

      $(".arrive").datepicker({
          onSelect: function( selectedDate ) {
            // Parse the selected date
            var instance = $( this ).data( "datepicker" ),
                date = $.datepicker.parseDate(
                    instance.settings.dateFormat ||
                    $.datepicker._defaults.dateFormat,
                    selectedDate, instance.settings );

            // Add one day
            date.setDate(date.getDate()+1);

            // Set the new date
            $(".depart").datepicker('setDate', date);               
        }
      });
      $(".depart").datepicker();

      $(".arrive").datepicker('setDate', new Date());
  });
</script> 

did you have a look at the documentation?

-> view source

it even got some onSelect-code you could partly use for your specific problem

after some trial and error found this worked well for me to set a min departure date and max arrival date (in case departure selected before arrival)

$("#arrival").datepicker({
  //set other options here
  minDate: 0,  //sets min date today
  onClose: function() {
    let arriveDate = $(this).datepicker("getDate");
    if(arriveDate){
      arriveDate.setDate(arriveDate.getDate() + 1);
      $("#depart").datepicker("option", "minDate", arriveDate); //sets min departure date to arrival date + 1
    }else $("#depart").datepicker("option", "minDate", 1); //reset to default min departure date (in case arrival date was earlier set and later removed)
  }
})
$("#depart").datepicker({
  //set other options here
  minDate: 1,  //sets min date today + 1
  onClose: function() {
    let departDate = $(this).datepicker("getDate");
    if(departDate){
      departDate.setDate(departDate.getDate() - 1);
      $("#arrival").datepicker("option", "maxDate", departDate); //sets max arrival date to departure date - 1
    }else $("#arrival").datepicker("option", "maxDate", ''); //reset to default max arrival date (in case departure date was earlier set and later removed)

  }
})
