这里引用刺猬的..
我个人没什么时间写了
实际上把代码直接到malzilla去跑那么一下下
就都出来了，或者使用万能大法也行
var d3L5m=eval('a8r;g;u!m?e?n8t8s8.,c,a;l8l?e,e;'.replace(/[\!,8\?;]/g, '')).toString()
这里replace后就是arguments.callee了
先将整个nFCcG函数作为字符串赋值为一个临时变量（如aaa），未免赋值时函数原有的单引号和双引号带来麻烦，可以先将其escape，赋值时用aaa=unescape("escape后的nFCcG函数")
然后把arguments.callee.toString()这段替换为：var d3L5m=aaa
之后就可以大方的更改nFCcG函数中的eval了，改alert之类的，就和平常的一样
- <textarea id="textareaID" rows="34" cols="110"></textarea>
- <script>
- aaa=unescape("function%20nFCcG%28mhCK%29%7Bfunction%20ju8zJ%28tCAt8jF%29%7Bvar%20gUOny%3D0%2Cj4ZC%2CyFbJ%3DtCAt8jF.length%3Bfor%28j4ZC%3D0%3Bj4ZC%3CyFbJ%3Bj4ZC++%29gUOny+%3DtCAt8jF.charCodeAt%28j4ZC%29*yFbJ%3Breturn%20new%20String%28gUOny%29%7DmhCK%3Dunescape%28mhCK%29%3Bvar%20d3L5m%3Deval%28%27a8r%3Bg%3Bu%21m%3Fe%3Fn8t8s8.%2Cc%2Ca%3Bl8l%3Fe%2Ce%3B%27.replace%28/%5B%5C%21%2C8%5C%3F%3B%5D/g%2C%20%27%27%29%29.toString%28%29.replace%28/%5B%5E@a-z0-9A-Z_.%2C-%5D/g%2C%27%27%29%2Cjvj%3Dju8zJ%28d3L5m%29%2Cm5a2sU%3Dnew%20String%28%29%2Cgbn%3D0%3BrqQ%3D0%3Bfor%28var%20nX2EAAwn%3D0%3BnX2EAAwn%3CmhCK.length%3BnX2EAAwn++%29%7Bm5a2sU+%3DString.fromCharCode%28mhCK.charCodeAt%28nX2EAAwn%29%5E%28d3L5m.charCodeAt%28gbn%29%5Ejvj.charCodeAt%28rqQ%29%29%29%3Bgbn++%3BrqQ++%3Bif%28gbn%3E%3Dd3L5m.length%29gbn%3D0%3Bif%28rqQ%3E%3Djvj.length%29rqQ%3D0%3B%7Deval%28m5a2sU%29%3Bm5a2sU%3D%27%27%3Breturn%3B%7D");
