Bootstrap datepicker return focus after select

If you initialize a bootstrap datepicker from eternicode with autoclose: true, two undesirable behaviors happen:

1. After the picker closes, when you tab into the next field, you'll start at the beginning of the document again. This can be quite cumbersome on long forms.
2. Because the picker changes the value programatically, any listeners that you have that care about the blur event on the input won't behave properly. The blur actually occurs when you select the picker value and the input's value hasn't changed. Then the bootstrap-datepicker programmatically updates the field so blur is never fired with the new value.

Here's a demo in stack snippets:
*select any field, select a value from the picker, and then hit <kbd>Tab</kbd>

<!-- begin snippet: js hide: false --> <!-- language: lang-js -->

$(".datepicker").datepicker({
  autoclose: true
});

According to the answer to Focus the field after selecting the jQuery UI datepicker, you can tap into the onClose or onSelect events, but the bootstrap picker doesn't offer those events.

Simply replacing them with hide doesn't seem to work either, since the refocusing will create an endless loop that always keeps the picker open any time you try to close it.

<!-- language: lang-js -->

$(".datepicker").datepicker({
  autoclose: true
})
.on('hide', function () {
  $(this).focus();
});

This is a little bit of a hack job, but you can conditionally hide and show the elements to avoid an infinite loop. On hide, check if this is the first time attempting to hide. If the input does not have focus (meaning they have used the dropdown and we've lost our tab order, then refocusing will cause the picker to show. We'll also catch this show and hide from there, entering back into our original code. We'll pass back and forth a property on the object so we can manage state.

That will look like this:

<!-- language: lang-js -->

$(".datepicker").datepicker({
  autoclose: true
})
.on('hide', function () {
  if (!this.firstHide) {
    if (!$(this).is(":focus")) {
      this.firstHide = true;
      // this will inadvertently call show (we're trying to hide!)
      this.focus(); 
    }
  } else {
    this.firstHide = false;
  }
})
.on('show', function () {
  if (this.firstHide) {
    // careful, we have an infinite loop!
    $(this).datepicker('hide'); 
  }
})

      this.focus();

  } else {
    this.firstHide = false;

    $(this).datepicker('hide');
