给他发了短消息，还没有回复我，我急着想要，谢谢！
顺便问问他的示例里：
<HEAD>
<TITLE> tester </TITLE>
<meta http-equiv='Content-Type' content='text/html; charset=gb2312'>
<script src="http://writeblog.csdn.net/scripts/jsframework.js"></script>
</HEAD>

<BODY>
<SCRIPT LANGUAGE="JavaScript">
Using("System.Web.UI.WebControls.MzTreeView");
var a = new System.Web.UI.WebControls.MzTreeView();

这里的/jsframework.js没看懂，是什么技术？
