eval(function(p,a,c,k,e,d) 加密破解和格式化JS代码最新算法
红色加粗部分将是要修改的地方.

其实这个eval(function(p,a,c,k,e,d){}))中自带解码函数e(). while(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c])}}return p while循环产生的每个p就是解码后的函数代码,我们删掉源码中的return p,不用将结果返回, 而是直接输出在一个文本区域中,如document.getElementById(”textareaID”).innerText=p.

保存为html文件,运行. 格式化文本区域中的JavaScript代码,代码如下:

修正以后发现一个更简单的方法..将eval直接替换成document.write,将代码输出,但是要注意一点.在输出前,先输出一个<xmp>标记 如:
document.write("<xmp>");
/*eval*/document.write("function(){.....代码}");
document.write("</xmp>");
输出后是一堆代码. 把Javascript格式化一下 格式化的网页工具 http://tool.chinaz.com/Tools/JsFormat.aspx
