遗留问题1：由于JScript.Encode无法动态生成，就涉及瓶颈问题，解密代码是显而易见的。

遗留问题2：Netsuite中如何类似系统那样动态在页面生成之前添加类似"

<script type\='text/javascript' src\='[/core/media/media.nl?id=7314&c=853509&h=19b09b403823dbebdf71&\_xt=.js](view-source:https://system.netsuite.com/core/media/media.nl?id=7314&c=853509&h=19b09b403823dbebdf71&_xt=.js)'\></script\>


"这类的代码。

必须页面在客户端生成之前产生。
