Hi, do you know why it doesn't work on my website?
http://nou4r.net/x/play/play.php?url=https://ok.ru/video/37675534991
function checkReq(){ var list = document.getElementById("gkpluginsExtListReq"); if(list===null){ return; } list.title = "ready"; if(list.childNodes.length>0){ var curReq = list.firstChild; if(typeof curReq.innerHTML=="undefined"){ list.removeChild(curReq); return; } var obj = JSON.parse(atob(curReq.innerHTML)); obj.onload = obj.onerror = obj.onabor = function(response){ var txtout = document.createElement("textarea"); txtout.id = obj.extreqid; txtout.style.display = "none"; var Hfres = response.status+" "+response.statusText+"\r\n"+response.responseHeaders; if(response.finalUrl){ Hfres += "FinalLocation: "+response.finalUrl+"\r\n"; } if(obj.returndtaescape){ txtout.value = escape(Hfres+"\r\n"+response.responseText); }else if(obj.returndtab64){ txtout.value = btoa(Hfres+"\r\n"+response.responseText); }else{ txtout.value = Hfres+"\r\n"+response.responseText; } document.body.appendChild(txtout); }; GM_xmlhttpRequest(obj); list.removeChild(curReq); } } setInterval(checkReq,100);
Works fine, if i load it via tampermonkey.
I'm not having any success with this either in the latest version of Chrome. I can't even get onMessage to fire?
