JS文件加密&解密，将下面的代码保存为html，运行即可!!!<script>a=62;function encode() {var code = document.getElementById('code').value;code = code.replace(/[\r\n]+/g, '');code = code.replace(/'/g, "\\'");var tmp = code.match(/\b(\w+)\b/g);tmp.sort();var dict = [];var i, t = '';for(var i=0; i<tmp.length; i++) { if(tmp != t) dict.push(t = tmp);}var len = dict.length;var ch;for(i=0; i<len; i++) { ch = num(i); code = code.replace(new RegExp('\\b'+dict+'\\b','g'), ch); if(ch == dict) dict = '';}document.getElementById('code').value = "eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d=k||e(c);k=}];e=function(){return'\\\\w+'};c=1};while(c--)if(k)p=p.replace(new RegExp('\\\\b'+e(c)+'\\\\b','g'),k);return p}(" + "'"+code+"',"+a+","+len+",'"+ dict.join('|')+"'.split('|'),0,{}))";}function num(c) {return(c<a?'':num(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36));}function run() {eval(document.getElementById('code').value);}function decode() {var code = document.getElementById('code').value;code = code.replace(/^eval/, '');document.getElementById('code').value = eval(code);}</script><textarea id=code cols=80 rows=20></textarea><br><input type=button onclick=encode() value=编码><input type=button onclick=run() value=执行><input type=button onclick=decode() value=解码>
