Answer 2

有报错饿..Uncaught ReferenceError: c35 is not defined

})();http://blog.csdn.net/superwfei/article/details/38436179 这里可以看到解密内容，只需要在 
var b = a;  
后面加上一句
b = b.replace(/\\x[0-9a-f]{2}/gi,function(m){eval(m.replace('\\x','var asc=0x'));return String.fromCharCode(asc);});

Answer 4

关键位置是把 c35 替换成 c<a?'':e ( parseInt ( c/a)))+ ( ( c=c%a)>354 楼回复有错误
