title: prevent validation while the datepicker has focus
body: <p>I'm using the jQuery-ui <a href="http://jqueryui.com/datepicker/" rel="nofollow noreferrer">datepicker</a> together with Jörn Zaefferer's <a href="http://docs.jquery.com/Plugins/Validation" rel="nofollow noreferrer">validate</a> plugin.</p>
  <p>It's well known that validate does not automatically fire <em>after</em> a datepicker changes the content of an input field.</p>
  <p>What I find curious is that validate <em>does</em> fire when the year dropdown is clicked, when the month dropdown is clicked and when the day is clicked. And, in none of these cases has the value of the input field been changed.  You can try for yourself here: <a href="http://jsfiddle.net/ECku3/12/" rel="nofollow noreferrer">http://jsfiddle.net/ECku3/12/</a> There are console.log events that show when the validation method is called and the value of the validated field when <code>$.validator.showErrors()</code> is called.</p>
  <h2>tl;dr</h2>
  <p>I would like to find a way to prevent validation while the datepicker has focus. But I do not want to prevent validation when a user types a date instead of using the datepicker. So I can't just set <code>$.validator.settings.onfocusout = false</code>.</p>
  <p>Ideas?</p>
