Ecode解密方法(源代码) - 王朝网络宽屏版

Encode，实际是一种不完全的Unicode 文本（见过Unicode 吗？汉字全是%uxxxx的），当表示英文或数字时，它与普通文本并无区别。但在表示各种控制符、特殊符号、扩展ASCII 字符（如汉字）甚至空格时，它就把它们全变成了%xx%xx的形式。

解密ENCODE有很多方法,我所提供的是一个网页的解密代码,代码如下：

<html>

<head>

<style>

td,select,input{font-size:10.5pt; color:#000000; height:16pt}

textarea{font-size:14; color:#000000}

a:link {text-decoration:none; color:#555555}

a:hover {text-decoration:underline; color:#555555; background-color:ffff00}

a:visited {text-decoration:none; color:#555555}

</style>

</head>

<BODY>
