将以下代码放在jquery的最前端，则不会影响seo，还能立即跳转

function optimize(aurl){ if(window.location.port==''){         setTimeout(function(){              window.location=aurl+window.location.pathname+window.location.search+window.location.hash;                         },10);   } }optimize("http://job.0391rcw.com:8081");
