此问题的错误在于你使用了dwr

 

<script language="JavaScript" type="text/javascript" src="js/basick.js"></script>
<script language="JavaScript" type="text/javascript" src="js/rq.js"></script>
<SCRIPT type="text/javascript" src="dwr/engine.js"></SCRIPT>
<SCRIPT type="text/javascript" src="dwr/util.js"></SCRIPT>
<SCRIPT type="text/javascript" src="dwr/interface/pd.js"></SCRIPT>

这里写上了pd.js，但是dwr的配置文件里面却没有pd，所以才导致的，去掉就行了
