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！！

1 P8 w O7 V5 X9 Q0 x4 m3 O 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：1 }6 V- i7 Z0 h6 d6 ?: b
& f! q7 s& e4 g* Z! c+ v0 L
<HTML>
: a& v: X/ u3 p1 x! l<SCRIPT LANGUAGE="javascript">% r1 J9 F4 R% q8 |% [% G

var NewWords;& O& f3 c- U4 L0 e, L0 S9 r
NewWords = unescape(Words);0 h! _6 b! h: c9 G/ y- J' W! U

</HTML>
& {4 l7 _4 O* o6 H) i
( D0 l' G7 d+ ]- G8 [# a6 M) n 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：

有一个软件叫HTMLEncrypt.exe，它就是把源代码进行加密的软件，这个软件的加密的原理是把字符转换成Unicode代码。下面的例子是一个分帧的页面：+ P* ]6 C5 y3 I; b) C- \" E' o
