Initialize JQuery Datepicker with a blank value
<p>This code still sets the field to today's date</p>

<pre><code>&lt;script type="text/javascript"&gt;
    $(document).ready(function () {
        $('.date').datepicker({ dateFormat: "mm/dd/yy", changeMonth: true,
            changeYear: true, yearRange: '1900:2020', defaultDate: ''
        });

    });

&lt;/script&gt;
</code></pre>

<p>How do I universally configure the field to start as blank?  </p>
