已经困扰我10天了~~~~  老师，高手们来看看呀~~~~

用神器解密，直接运行脚本。

:kaka1: 老师一句话完事

是这样么老师？里面没有eavl函数呀，提示无法运行，是不是需要把代码加工一下？

http://bbs.ikaka.com/showtopic.aspx?topicid=8694694&page=2
19楼我说的很清楚了

老师，您说的也太简略了吧~~~
按照您的解释尝试了一下，与楼上是同样的结果
等待老师给出详细的解释
困惑中~~~:kaka8:

1、在那一期的下载文件中没有document。write函数啊~~~~:kaka4:
2、怀疑是这段代码里有“终止符”导致一些工具获取不全代码。那么这个“终止符”又是什么呢？
3、直接用alert输出，完全没有对话框出现:kaka18: 真的是欲哭无泪了~~~~
4、难道这和浏览器版本有关系啊啊？？

感谢大牛，在此膜拜~~~~~:kaka9:

怎么觉得很像有B64~~？是不是要先换B64，再提取地址呢？

地址呢:kaka6: 还有你的代码全不全？

不过好像已经失效了，也看出代码不全~如7楼~  谢谢老师回答~

没有失效呀，里面不是有个document.write嘛。使用神器解密的时候需要删除script标签。

老天啊  谢谢老师，用了各种工具  终于把这个顽固的马给弄出来了，为什么FreShow会获取代码不全呢？？

终止符的关系

终止符的关系 :kaka2:  啥叫终止符。
