JQuery UI Datepicker loses focus when selecting date with mouse

Thanks for the suggestion Jeff, I modified your onSelect function to use the attribute filter to retrieve only elements with the tabindex specified by "nexttab".

$(function(){
  $(".date").datepicker({
      onSelect: function(){
          currenttab = $(el).attr("tabindex");
          nexttab = currenttab * 1 + 1;
          $("[tabindex='" + nexttab + "']").focus();
      }
  });
});

PS: If you don't have tabindexes specified in your code, like I neglected to do earlier, simply add the following code:

$('input, select').each(function(i, val){
    $(this).attr('tabindex', i + 1);
});

Subscribe to the onClose or the onSelect event:

$("#someinput").datepicker(
{
    // other options goes here
    onSelect: function ()
    {
        // The "this" keyword refers to the input (in this case: #someinput)
        this.focus();
    }
});

Or in the case of onClose:

$("#someinput").datepicker(
{
    onClose: function ()
    {
        this.focus();
    }
});

Similar to Jimmy's approach, but this sets the focus to the calendar icon (assuming your calender uses an icon), I found this way more appropriate when I had multiple date pickers next to each other.

Set the date default options so that they set focus to the icon when the calendar popup closes:

    $(".date").datepicker({
        onClose: function() {
            $(this).next('a').focus(); 
        }
    });

Add a tag to the calendar icon so that it's focusable:

    $(".date").each(function() {
        $($(this).next('img')).wrap($("<A/>").attr("href","#"));
    });
