javascript又一解密过程,推荐的，会这个基本上好多都能解决了
[常规准备]

1、首先尝试掌握代码的大体结构。

这需要一定的经验。首先是做hutia已经做了的事情（虽然这一步在这个具体的情况下也可以跳过，但是不推荐如此），先把编码的文字显形。有很多办法可选，有一种办法是把编码的字符串写到textarea里。

于是就得到了如下代码:

window["eval"]("XXX") 其实就是 window.eval("XXX")的另一种写法。

我们要关心的是作为eval()方法的参数的代码的结构。

把这些代码稍微整理一下（可用带语法高亮的编辑器，也可通过批量替换字符进行代码的格式化，使成对的{}、''和""显得突出），这样就能够看出代码的大致结构如下。
复制代码 代码如下:
function(j1,J2,picknick,La4,oddver,outputver)
{

oddver=function(picknick)
{
return(picknick35?String.fromCharCode(picknick+29):picknick.toString(36))
}

if(true)
{
while(picknick--)outputver[oddver(picknick)]=La4[picknick]||oddver(picknick);

La4=[function(oddver){return outputver[oddver]}];

oddver=function()
{
return 'w+'
}
picknick=1
}
while(picknick--)if(La4[picknick])j1=j1.replace(new RegExp('b'+oddver(picknick)+'b','g'),La4[picknick]);

return j1
}(……)

那么整个代码的结构就相当于这个样子：
复制代码 代码如下:
