才发现的破解javascript各种加密的反向思维方法,大家有好的方法都跟帖啊
最近发现了一个代码，加密了5层左右，我将破解到最后一步，而且不用javascript解密程序 

用到的软件列表  
  1、迅雷（下载网页）直接浏览会执行的，看不到源代码 
  2、或用firefox这个软件可以直接浏览网址，由于firefox的特殊性，也推荐用这个浏览器 
一、目标网址 http://www.e9ad.cn/pcdd/80-806.htm 
我们用迅雷下载这个页面或用firefox浏览器浏览得到如下代码 
复制代码 代码如下:
 
<script language=javascript>var DFQC=function(a){return String.fromCharCode

对于这个的解密呢，分析下 
大家看下document.write(DFQC(42)+DFQC(126)..... 
这个DFQC(42)，的DFQC就是解密var DFQC=function(a){return String.fromCharCode(a^22)} 
下面我的解密代码也想好了，这个方法基本上可以破解好多的类似代码，大家可以看下这个代码
