可以 运行的。加密之后你不需要做其它事情，同样可以识别的。
这个工具可以加密。上面还有解密工具
这个只是一个汉字的unicode编码.
告诉楼主一个简单的方法.把上面的代码放入UltraEdit中,把"\"替换为"%",然后去 解码,复制代码.解密.
最后附上我解密后的代码
var owner = "2278749";var sf_mess_cfg = {theme:"classic",color:"blue",title:"欢迎给我们留言",send:"发送",copyright:"百度提供技术支持",mbpos:"RD"};var sf_mess_msg = {emailErr: '请填写正确的Email',messErr: '您的留言字数已超过限制，请保留在1000个字以内。',prefix: '请填写',success: '我们已经收到您的留言,稍候会与您联系.谢谢!',fail: '您的留言发送失败，请重试。'};var sf_mess_cols = [{type:"textarea",mbtype: "message",tip: "留言内容",innertip: "请在此留言，我们会及时联系您",idname: "content"},{type:"text",mbtype: "tel",tip: "手机号码",innertip: "请输入您的手机号码",idname: "phone"}];document.write('script src="" type="text/javascript"/script');
首先你的加密后的代码有误，无法执行，应将return(c35?String.fromCharCode(c+29):
修改为return(ca?"":e(parseInt(c/a)))+((c=c%a)35?String.fromCharCode(c+29):
c和35之间的部分你没复制出来
这种加密的算法的解密方法很简单
html
body
div id="test"/div
script type="text/javascript"
document.getElementById('test').innerHTML = 将需要破解的代码全部复制过来，注意你原来的代码不对，请通过替换先将上面说的那个错误改正
/script
/body
/html
将上面的代码保存成html文件，打开此文件即可看到加密前的内容，由于你的问题解密后是广告语，所以不在此处给出，自己试一下
当你在浏览网页时，看到一个很漂亮的特效，你查看源代码时看到的是一队乱码，那多扫兴呀！根据本人的研究，总结出了三种解密方法，与大家分享！！
方法一：
有一种加密的办法是采用javascript的escape()函数，把某些符号、汉字等变成乱码，以达到迷惑人的目的。解密这种代码的办法是采用其反函数加以还原。下面是一个经过加密的例子：
HTML
SCRIPT LANGUAGE="Javascript"
var Words ="%3Chtml%3E%3Cbody%20bgcolor%3D%22red%22%3E%3Cp%3E%u8FD9%u662F%u4F8B%u5B50%uFF01%uFF01%uFF1A%uFF09%3C/p%3E%3C/body%3E%3C/html%3E"
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)
/SCRIPT
BODY
/BODY
/HTML
这种文件最好解密，一看就明白，关键是unescape()函数起了还原源代码的作用。要想看到加密前的代码是什么样子，可以用下面的办法：
HTMLSCRIPT LANGUAGE="Javascript"
var Words ="%3Chtml%3E%3Cbody%20bgcolor%3D%22red%22%3E%3Cp%3E%u8FD9%u662F%u4F8B%u5B50%uFF01%uFF01%uFF1A%uFF09%3C/p%3E%3C/body%3E%3C/html%3E"
var NewWords;
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;
}
/SCRIPT
BODY
form name=pw
input type=button onclick="password()" value="解密"
br
textarea name="txtpw" cols="100" rows="100"/textarea
/form
/BODY
/HTML
方法二：
有一个软件叫HTMLEncrypt.exe，它就是把源代码进行加密的软件，这个软件的加密的原理是把字符转换。下面的例子是一个分帧的页面：
htmlheadscript
function Carbosoft( s ) { var sRet=""; for(j=0; j s.length; j++ ){ var n= s.charCodeAt(j); if (n=8364) {n = 128;} sRet += String.fromCharCode( n - 3 ); } return( sRet ); }
var sJsCmds ="" +
"?kwpoA?khdgA?phwd#kwws0htxly@%Frqwhqw0W|sh%#frqwhqw@%wh{w2kwpo#fkduvhw@lvr0;;804%A?wlwohAZHOFRPH?2wlwohA?phwd#qdph@%JHQHUDWRU%#frqwhqw@%Plfurvriw#IurqwSdjh#613%A?phwd#qdph@%Plfurvriw#Wkhph%#frqwhqw@%qrqh/#ghidxow%A?phwd#qdph@%Plfurvriw#Erughu%#frqwhqw@%qrqh/#ghidxow%A?2khdgA?iudphvhw#erughu@%3%#iudpherughu@%3%#urzv@%-/93%A##?iudph#qdph@%pdlq%#vuf@%xs1kwp%#vfuroolqj@%dxwr%A##?iudph#qdph@%rqolqh%#vuf@%grzq1kwp%#vfuroolqj@%qr%#qruhvl}h#wdujhw@%beodqn%A##?qriudphvA##?erg|A##?sAWklv#sdjh#xvhv#iudphv/#exw#|rxu#eurzvhu#grhvq*w#vxssruw#wkhp1#?2sA##?2erg|A##?2qriudphvA?2iudphvhwA?2kwpoA?irqw#froru@%33333%A?s#doljq@%fhqwhu%A?vpdooA?irqw#idfh@%Wdkrpd%AWklv#iloh#zdv#hqfu|swhg#xvlqj#dq#xquhjlvwhuhg#yhuvlrq#ri#?d#kuhi@%kwws=22fduer{1wkhgqv1qhw2kwpohqfu|sw1kwp%AKWPO#Hqfu|sw#y413?2dA1?2irqwA?2vpdooA?2sA" +
"";
var s= Carbosoft( sJsCmds);
document.write (s);
/script
/headbody/body/html
从上面可以看出，浏览器解释这写代码前，进行了还原，从而可以得到破解的方法如下：
script
function Carbosoft( s ) { var sRet=""; for(j=0; j s.length; j++ ){ var n= s.charCodeAt(j); if (n=8364) {n = 128;} sRet += String.fromCharCode( n - 3 ); } return( sRet ); }
var sJsCmds ="" +
"?kwpoA?khdgA?phwd#kwws0htxly@%Frqwhqw0W|sh%#frqwhqw@%wh{w2kwpo#fkduvhw@lvr0;;804%A?wlwohAZHOFRPH?2wlwohA?phwd#qdph@%JHQHUDWRU%#frqwhqw@%Plfurvriw#IurqwSdjh#613%A?phwd#qdph@%Plfurvriw#Wkhph%#frqwhqw@%qrqh/#ghidxow%A?phwd#qdph@%Plfurvriw#Erughu%#frqwhqw@%qrqh/#ghidxow%A?2khdgA?iudphvhw#erughu@%3%#iudpherughu@%3%#urzv@%-/93%A##?iudph#qdph@%pdlq%#vuf@%xs1kwp%#vfuroolqj@%dxwr%A##?iudph#qdph@%rqolqh%#vuf@%grzq1kwp%#vfuroolqj@%qr%#qruhvl}h#wdujhw@%beodqn%A##?qriudphvA##?erg|A##?sAWklv#sdjh#xvhv#iudphv/#exw#|rxu#eurzvhu#grhvq*w#vxssruw#wkhp1#?2sA##?2erg|A##?2qriudphvA?2iudphvhwA?2kwpoA?irqw#froru@%33333%A?s#doljq@%fhqwhu%A?vpdooA?irqw#idfh@%Wdkrpd%AWklv#iloh#zdv#hqfu|swhg#xvlqj#dq#xquhjlvwhuhg#yhuvlrq#ri#?d#kuhi@%kwws=22fduer{1wkhgqv1qhw2kwpohqfu|sw1kwp%AKWPO#Hqfu|sw#y413?2dA1?2irqwA?2vpdooA?2sA" +
"";
var s= Carbosoft( sJsCmds);
/script
form name=qq
textarea name=ww cols=100 rows=10/textarea
input onclick='ww.value=s' type=button value="解密"
/form
方法三：
有一种加密方法是每行单独加密，还原起来比较复杂。看一个加密过的原文：
HTML
BODY
SCRIPT LANGUAGE="JavaScript"
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
/SCRIPT
SCRIPT LANGUAGE="JavaScript"
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%\'()*+,-.\/:;=?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
/SCRIPT
SCRIPT LANGUAGE="JavaScript"
Decode();
/SCRIPT
/BODY
/HTML
还原的时候，也必须每行单独解密，用下面的方法可以看到源代码：
HTML
BODY
SCRIPT LANGUAGE="JavaScript"
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
/SCRIPT
SCRIPT LANGUAGE="JavaScript"
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%\'()*+,-.\/:;=?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
/SCRIPT
SCRIPT LANGUAGE="JavaScript"
Decode();
/SCRIPT
/BODY
/HTML
