网页加密WEB页代码

好么，当初我发这篇的时候CSDN博客还没有插入代码的编辑项呢是怎么的。


<html>
<head>
<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>网页加密</title>
<script language="javascript">
function encrypt()
{   // 加密
 var SourceCode;
 SourceCode=document.F1.S1.value;
 //alert(SourceCode);
 if(SourceCode=="") { alert("没有可以加密的代码！[原始代码]框中没有内容。"); return; }
 document.F1.S2.value=encodeURIComponent(SourceCode);
}
function decode()
{   //译码
 var DecodeStr;
 DecodeStr=document.F1.S2.value;
 //alert(DecodeStr);
 if(DecodeStr=="") {alert("没有被加密的代码来还原！[加密后代码]框中没有内容。"); return; }
 document.F1.S1.value=decodeURIComponent(DecodeStr);
}

function exchange()
{
 if(document.F1.R1[0].checked) encrypt();
 else if(document.F1.R1[1].checked ) decode();
 else alert("没选择“加密/解密”按扭");
}
</script>
