  encode|编码|脚本编码示例


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">

//-->
</SCRIPT>
</HEAD>
<BODY onload="getAppropriatePage()">
</BODY>
</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。
