<div id="selector">
  <p>Drag me around and click me.</p>
  <p>I change color when I receive a "click" event.</p>
</div>

<script type="text/javascript" src="http://threedubmedia.googlecode.com/files/jquery.event.drag-2.0.js"></script>

CSS

.red { background: rgba(255, 0, 0, .6); }

#draggable { width: 150px; height: 100px; padding: 0.5em; border: 1px solid black; position: relative; }

JavaScript

function log() {  // Logs text in the page (instead of console.log())
    $("#console").append($("<p/>", {
        text: Array.prototype.join.call(arguments, ", ")
    }));
}
// getter
var appendTo = $( ".selector" ).draggable( "option", "appendTo" );
 
// setter
$( ".selector" ).draggable( "option", "appendTo", "body" );
