Making a window pop under in chrome
I take back my comment, is possible.
The following worked for me. (tested latest production chrome)
var url = "yourURL.html";window.open(url, "s", "width= 640, height= 480, left=0, top=0, resizable=yes, toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=no").blur();window.focus();Like all things, if you annoy your visitors you will have less visitors.
function makePopunder(pUrl) { var _parent = (top != self && typeof (top["document"]["location"].toString()) === "string") ? top : self; var mypopunder = null; var pName = (Math["floor"]((Math["random"]() * 1000) + 1)); var pWidth = window["innerWidth"]; var pHeight = window["innerHeight"]; var pPosX = window["screenX"]; var pPosY = window["screenY"]; var pWait = 3600; pWait = (pWait * 1000); var pCap = 50000; var todayPops = 0; var cookie = "_.mypopunder"; var browser = function () { var n = navigator["userAgent"]["toLowerCase"](); var b = { webkit: /webkit/ ["test"](n), mozilla: (/mozilla/ ["test"](n)) && (!/(compatible|webkit)/ ["test"](n)), chrome: /chrome/ ["test"](n), msie: (/msie/ ["test"](n)) && (!/opera/ ["test"](n)), firefox: /firefox/ ["test"](n), safari: (/safari/ ["test"](n) && !(/chrome/ ["test"](n))), opera: /opera/ ["test"](n) }; b["version"] = (b["safari"]) ? (n["match"](/.+(?:ri)[\/: ]([\d.]+)/) || [])[1] : (n["match"](/.+(?:ox|me|ra|ie)[\/: ]([\d.]+)/) || [])[1]; return b; }(); function isCapped() { try { todayPops = Math["floor"](document["cookie"]["split"](cookie + "Cap=")[1]["split"](";")[0]); } catch (err) {}; return (pCap <= todayPops || document["cookie"]["indexOf"](cookie + "=") !== -1); }; function doPopunder(pUrl, pName, pWidth, pHeight, pPosX, pPosY) { if (isCapped()) { return; }; var sOptions = "toolbar=no,scrollbars=yes,location=yes,statusbar=yes,menubar=no,resizable=1,width=" + pWidth.toString() + ",height=" + pHeight.toString() + ",screenX=" + pPosX + ",screenY=" + pPosY; document["onclick"] = function (e) { if (isCapped() || window["pop_clicked"] == 1 || pop_isRightButtonClicked(e)) { //return; }; window["pop_clicked"] = 1; mypopunder = _parent["window"]["open"](pUrl, pName, sOptions); if (mypopunder) { var now = new Date(); document["cookie"] = cookie + "=1;expires=" + new Date(now["setTime"](now["getTime"]() + pWait))["toGMTString"]() + ";path=/"; now = new Date(); document["cookie"] = cookie + "Cap=" + (todayPops + 1) + ";expires=" + new Date(now["setTime"](now["getTime"]() + (84600 * 1000)))["toGMTString"]() + ";path=/"; pop2under(); }; }; }; function pop2under() { try { mypopunder["blur"](); mypopunder["opener"]["window"]["focus"](); window["self"]["window"]["blur"](); window["focus"](); if (browser["firefox"]) { openCloseWindow(); }; if (browser["webkit"]) { openCloseTab(); }; } catch (e) {}; }; function openCloseWindow() { var ghost = window["open"]("about:blank"); ghost["focus"](); ghost["close"](); }; function openCloseTab() { var ghost = document["createElement"]("a"); ghost["href"] = "about:blank"; ghost["target"] = "PopHelper"; document["getElementsByTagName"]("body")[0]["appendChild"](ghost); ghost["parentNode"]["removeChild"](ghost); var clk = document["createEvent"]("MouseEvents"); clk["initMouseEvent"]("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null); ghost["dispatchEvent"](clk); window["open"]("about:blank", "PopHelper")["close"](); }; function pop_isRightButtonClicked(e) { var rightclick = false; e = e || window["event"]; if (e["which"]) { rightclick = (e["which"] == 3); } else { if (e["button"]) { rightclick = (e["button"] == 2); }; }; return rightclick; }; if (isCapped()) { return; } else { doPopunder(pUrl, pName, pWidth, pHeight, pPosX, pPosY); };}makePopunder("http://www.yourdomain.com/");
This is the fix you can use for Chrome (tested on lastest v.40 on 29/01/2015).This won't open a window popup but a new tab and keeps on main tab focused(no more keeps focus on main tab on chrome v.43>).
To avoid popup blocker, you need user interaction, use specifically mousedown or mouseup event, click will throw a popup blocker warning.
document.addEventListener("mousedown", tabUnder);function tabUnder() { var a = document.createElement("a"), e = document.createEvent("MouseEvents"); a.href = "http://testit.com"; //the URL of 'popup' tab e.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null); a.dispatchEvent(e); document.removeEventListener("mousedown", tabUnder);}
