<h1 style="color:#ffa500; text-align:center">JScript.Encode 脚本在线解密</h1> 
<b style="color:#f6f">用途</b>:
 
  1. 解密英文信函（如果您想加密/解密中文信函等等，请查阅 <a href="uniendecode.htm" style="color: #f90;" target=_blank>文本 Unicode 码加密与解密</a> ）；
 
  2. 秘密数字信息；
 
  3. BBS 等上面发布英文、数字留言；
 
  4. 网页解密。

此类 JScript.Encode 码解密，只解密英文、符号，对中文文字不解密。
 
  使用本页面可以解密 javascript 函数，将 script 标记中的内容复制后进行解密(可多次解密),然后将标记修改为 <em><script language="javascript"></em> 即可。

<b>使用方法</b>：
 
   <font color=#ff66ff>解密</font>：源代码粘贴在下面的框内，<font color=#ff66ff>请在解密前先备份您的网页</font>
 
   <font color=#ff66ff>解密方法</font>：将引号内的乱码贴入按解密即可

如果下面无法解密，常见的是以下两种情况：
 
  1. 是 unescape 码加密解密，请访问  <a href="uniendecode.htm" style="color: #f90;" target=_blank>文本 Unicode 码加密与解密</a> ）；
 
  2. 多次加密，那么您就多按几次解密直到可以阅读为止，Unicode 解密也有这种情况。

<P >  <b style="color:#f6f">说明</b>：解密时应只解密脚本部分，加密脚本标记为 <em><script language="JScript.Encode"></em> ，解密后脚本标记应改为：<em><script language="javascript"></em></P> 
<P><u><b style="color:#f6f">特别注意</b></u>：<b style="color:#f6f">本页面以及您解密后的 jscript 一般只可以在 IE 中运行</b>。此页为 JScript.Encode 解密及加密(暂只能用 M$ 的编码器 Script Encoder 加密)，但是个别动态网页脚本加密后不能使用。</P>
