配置网页成为可以拖拽到脚本：
<img src="images/image1.jpg" style="float:left" class="dragableElement"> <div id="keyText" class="dragableElement">You can drag this box as well as the images on this page</div>
配置客户端记住拖拽后的位置：
<script type="text/javascript">
var rememberPositionedInCookie = true;
var rememberPosition_cookieName = 'demo';
</script>
