之前开了一个帖子求教如何decode代码：
http://bbs.csdn.net/topics/390294314cn00439804兄提供了结果，B_Lee兄提供了方法。但菜鸟如我依然毫无思路。现在就想请教高手，如果这样的代码自己动手解压，怎么做？如果自己的代码也想这样压缩，怎么做？算是两个问题吧，但分开开两个帖子似乎有点罗嗦。希望100分别嫌少呀，呵呵

JS混淆加密压缩
就可以得到压缩代码
解压嘛 就是这个函数
function (p, a, c, k, e, d) {
e = function (c) {
return (c < a ? '' : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if (!''.replace(/^/, String)) {
while (c--) {
d[e(c)] = k[c] || e(c)
}
k = [function (e) {
return d[e]
}];
e = function () {
return '\\w+'
};
c = 1
};
while (c--) {
if (k[c]) {
p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c]) //主要是在这一句
}
}
return p
}
输出p的值就行了
e = function (c) {
return(c35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if(!''.replace(/^/, String)) {
while(c--) {
d[e(c)] = k[c] || e(c)
}
k = [function (e) {
return d[e]
}];
e = function () {
return '\\w+'
};
c = 1
};
while(c--) {
if(k[c]) {
p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c])
}
}
return p
}
网上有些文章教怎么解就是把return p的这个值直接输出就能看到。但这个代码如果使用此方法就会出现c35 is undefined错误。
恩，输出当然可以用alert啦 但问题是一开始不知道原理 知道了返回的是p就不是问题了 但，问题就是，你们引用的那个加密程序和我说的不是一个，你自己动手试试我的那个就知道了，出错，出了错就不会alert了，明白？

hujife兄，请你手把手啊 上面的指导 相当于告诉为A可以得出B 我是想知道A如何得出B呀，你有点太跳跃了 当然，也许是我太没悟性 你就多费心讲一下过程吧 我按照之前你说的把 return p修改为alert(p)，但出错了，不能直接输出呀 应该怎么做一下就能输出解码后的代码呢？
看来CSDN网友很强大，估计站长看到这么多人关注他的代码，知道肯定hold不住了，索性放开了吧主要不是偷窥人家的代码，是想学习一下这个方法
Afunction(p, a, c, k, e, d) {
e = function(c) {
return (c35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if (!''.replace(/^/, String)) {
while (c--) {
d[e(c)] = k[c] || e(c)
}
k = [function(e) {
return d[e]
}];
e = function() {
return '\\w+'
};
c = 1
};
while (c--) {
if (k[c]) {
p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c])
}
}
return p
}
Bfunction(p, a, c, k, e, d) {
e = function(c) {
return (c < a ? "": e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if (!''.replace(/^/, String)) {
while (c--) d[e(c)] = k[c] || e(c);
k = [function(e) {
return d[e]
}];
e = function() {
return '\\w+'
};
c = 1;
};
while (c--) if (k[c]) p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c]);
return p;
}看出差别了吧
c35=c < a ? "": e(parseInt(c / a))) + ((c = c % a) > 35;
<script>
eval(function (p, a, c, k, e, d) {
e = function (c) {

return (c < a ? "": e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if(!''.replace(/^/, String)) {
while(c--) {
d[e(c)] = k[c] || e(c)
}
k = [function (e) {
return d[e]
}];
e = function () {
return '\\w+'
};
c = 1
};
while(c--) {
if(k[c]) {
p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c])
}
}
