編碼示例
如下是一個包含需要保護的 JScript 代碼的簡短示例:
<Html>
<HEAD>
<TITLE>腳本編碼器示例頁</TITLE>
<SCRIPT LANGUAGE="JScript">
<!--//
//Copyright© 1998 Microsoft Corporation. All Rights Reserved.
//**開始編碼**
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>
該頁在經腳本編碼器運行後如下所示:
<Html>
<HEAD>
<TITLE>腳本編碼器示例頁</TITLE>
<SCRIPT LANGUAGE="JScript.Encode">

要點 :經過編碼後,如果您改動編碼後的文本,哪怕只改動一個字。腳本的完整性就會丟失,從而不能再使用。
