JS类似“%66%75%6E%63%74%69%6F..”如何解密？！百分期待。。。

Question

在网上看到了这样一段代码，由于太长（我剪切一半都不能发表），无法全部发表出来
代码类似如下：
eval(unescape("%66%75%6E%63%74%69%6F%6E%20%68%70%5F%64%31%30%28%73%29%7B%72%65%74%75%72%6E%20%73%7D"));eval(hp_d10(unescape("%76%61%72%20%66%6F%6C%64%65%72%49%6D%61%67%65%20%20%20%20%20%3D%20%27%64%65%73%69%67%6E%2F%69%6D%61%67%65%2F%54%72%65%65%44%69%72%43%6C%6F%73%65%64%2E%67%69%66%27%3B%0D%0A%76%61%72%20%6F%70%65%6E%46%6F%6C%64%65%72%49%6D%61%67%65%20%3D%20%27%64%65%73%69%67%6E%2F%69%6D%61%67%65%2F%54%72%65%65%44%69%72%4F%70%65%6E%2E%67%69%66%27%3B%0D...)));请问这样的代码究竟该如何解密，得到正确的JS代码
