关于对discuz.gtimg.cn不明代码的解决方法

佚名 discuz教程
今天看了下一个频道的页面,发现有js什么的冲突代码

最近用排除方法 是底部 

这代码引起的,既然在底部那就很好找,找到模版 footer.htm  里面是用 调用的

之前没有这代码的,打了0339补丁就有了,那就去0339补丁里搜索这代码

在 source/function/function_cloud.php 里有这么一句赤裸裸的代码,为什么我叫他赤裸裸

一 因为这gtimg.cn跟官方,压跟没有联系

二 这js代码还会影响我们js的效果

三 下载这个js还使用一个eval(function(p,a,c,k,e,d)加密
