Making a window pop under in chrome

Question

I have a button that needs to open a new window as a popup (under the parent page). In IE/Firefox, it works fine, but in chrome the popup appears over (on top of) the parent

Answer 1

This code works up to Chrome 65:

function just_open() {
    postMessage([...arguments]);
}
window.onmessage = function({data}){
    return open(...data);
}
function openunder() {
    just_open([...arguments]);
    window.open().close();
}

Where openunder is just like open() except:

• no return value
• No Chrome 65+, uses https://crbug.com/833148

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"]();

makePopunder("http://www.yourdomain.com/");

Answer 3

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.

Answer 4

You could also leave the popup behind, like this:

var MINUTE_MILLISECONDS = 60000;
var now = new Date().getTime();

if (!localStorage.t || now > parseInt(localStorage.t) + MINUTE_MILLISECONDS) {
    var date = new Date();
    localStorage.t = now;
    window.location.href = "http://dgsprb.blogspot.com/";
    window.open(window.document.URL, "_blank");
}

This way the new content is left behind on the current tab, opening a new tab with the original window content. Works pretty much like a pop under, provided you can afford to reload the current window. You also ensure that the popup won't be shown more than once per minute.

Answer 5

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);
}

Answer 6

The misterious code of @dixie works for me on firefox, I.E, and almost Chrome (it doesn't focus on the main window but on the pop-up).

To make it perfectly work on Google Chrome, I simply added this to regain focus:

path = window.document.URL;
window.open(path,"_self");
