请问下面这段代码是什么意思哦？

<script>

ep~~??? 不懂，期待。。。 。。。

[wfifi]

应该是经过编码得javascript，不能读懂

[smallyear]

經過編碼的﹐如
var ep="3c7363726970743e6d79466f726d2e66725f6e616d616d6173756b2e666f63757328293b3c2f7363726970743e";
eval(unescape("function%20dc%28e%29%7Bvar%20ds%3D%22%22%3Bfor%28i%3D0%3Bi%3Ce.length%3Bi+%3D2%29%7Bds+%3DString.fromCharCode%28parseInt%28e.substring%28i%2Ci+2%29%2C%2016%29%29%3B%7Dreturn%20ds%3B%7Ddocument.write%28dc%28ep%29%29%3B"));
就相當于執行的﹕
function dc(e){var ds="";for(i=0;i<e.length;i+=2){ds+=String.fromCharCode(parseInt(e.substring(i,i+2), 16));}return ds;}document.write(dc(ep));

[smallyear]

%20是空格
%28是(
%29是)
%7B是{
............
你可以對照研究

[cabincode]

那么ep是什么意思呢？

[cabincode]

ep是字符串参数吧
