当你在浏览网页时，看到一个很漂亮的特效，你查看源代码时看到的是一队乱码，那多扫兴呀！根据本人的研究，总结出了三种解密方法，与大家分享！！. p7 U5 h& M, D( t7 R

# ~8 p+ X" n+ u9 O& E) K# G' f
2 S! O, V4 y; y/ r& p" t$ ?0 G
有一种加密的办法是采用javascript的escape()函数，把某些符号、汉字等变成乱码，以达到迷惑人的目的。解密这种代码的办法是采用其反函数加以还原。下面是一个经过加密的例子：
( [+ d% A% U1 F1 J+ h4 K" G( \" w9 t6 Y# l! E4 N6 Z
<HTML>
9 W- B% F4 m0 V$ }0 ?<SCRIPT LANGUAGE="javascript">" a/ |/ r! n. p8 X& N

var NewWords;
2 R* P' X! n' M# D2 `; qNewWords = unescape(Words);
3 m# B* }$ U% ^) X" ^document.write(NewWords)

</BODY>
( M- r; A" c/ ?0 [& M9 R</HTML>' Z# h6 f0 r" @. F& ~# M- E
- m1 y: m* p( B3 R
这种文件最好解密，一看就明白，关键是unescape()函数起了还原源代码的作用。要想看到加密前的代码是什么样子，可以用下面的办法：2 j) \' l- N' [+ n8 x2 [

从上面可以看出，浏览器解释这写代码前，进行了还原，从而可以得到破解的方法如下：
