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！！5 k* ]/ U: D% Q$ Z, f# b7 W# s. c( U$ E) c
x N4 d1 h8 y. ~* J9 h, I
9 W% H6 R% U- z方法一：( F$ o* b. p5 v4 d# Y. |2 R/ m; C) K1 |
2 n7 a- C7 \+ z
$ v/ C. L- R+ z& U 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：/ E4 U8 X* Z R# U+ H r
8 D* S+ `8 k5 j. [0 b8 ]<HTML>
# F4 u) F# a8 {" [<SCRIPT LANGUAGE="javascript">

NewWords = unescape(Words);
