编码示例
如下是一个包含需要保护的 jscript 代码的简短示例：
<html>
<head>
<title>脚本编码器示例页</title>
<script language="jscript">
<!–//
//copyright© 1998 microsoft corporation. all rights reserved.
//**开始编码**
function verifycorrectbrowser(){
if(navigator.appname == "microsoft internet explorer")
if (navigator.appversion.indexof ("5.") >= 0)
return(true);
else
return(false);
}
function getappropriatepage(){
var str1 = "had this been an actual web site, a page compatible with ";
var str2 = "browsers other than ";
var str3 = "microsoft internet explorer 5.0 ";
var str4 = "would have been loaded.";
if (verifycorrectbrowser())
document.write(str1 + str3 + str4);
else
document.write(str1 + str2 + str3 + str4);
}
//–>
</script>
</head>
<body onload="getappropriatepage()">
</body>
</html>
该页在经脚本编码器运行后如下所示：
<html>
<head>
<title>脚本编码器示例页</title>
<script language="jscript.encode">

<body onload="getappropriatepage()">

</html>
要点 ：经过编码后，如果您改动编码后的文本，哪怕只改动一个字。脚本的完整性就会丢失，从而不能再使用。
