Set title in the window popup

Since popup.onload does not seem to work, here is a workaround: http://jsfiddle.net/WJdbk/.

var win = window.open('', 'foo', ''); // open popup

function check() {
    if(win.document) { // if loaded
        win.document.title = "test"; // set title
    } else { // if not loaded yet
        setTimeout(check, 10); // check in another 10ms
    }
}

check(); // start checking

I was having problems with the accepted answer until I realized that if you open an existing, slow page that already has a <title> the browser will 1) set your title, then 2) once the document fully loads it will (re)set the popup title with the "normal" value.

So, introducing a reasonable delay (function openPopupWithTitle):

var overridePopupTitle = function(popup, title, delayFinal, delayRepeat) {
    // https://stackoverflow.com/a/7501545/1037948
    // delay writing the title until after it's fully loaded,
    // because the webpage's actual title may take some time to appear
    if(popup.document) setTimeout(function() { popup.document.title = title; }, delayFinal || 1000);
    else setTimeout(function() { overridePopupTitle(popup, title); }, delayRepeat || 100);
}
var openPopupWithTitle = function(url, title, settings, delay) {
    var win = window.open(url, title, settings);
    overridePopupTitle(win, title, delay);
    return win;
}

None of these answers worked for me. I was trying to open a popup with a PDF inside and kept getting permission denied trying to set the title using the above methods. I finally found another post that pointed me in the correct direction. Below is the code I ended up using.

    var winLookup;
    var showToolbar = false;

    function openReportWindow(m_title, m_url, m_width, m_height)
    {
        var strURL;
        var intLeft, intTop;

        strURL = m_url;

        // Check if we've got an open window.
        if ((winLookup) && (!winLookup.closed))
            winLookup.close();

        // Set up the window so that it's centered.
        intLeft = (screen.width) ? ((screen.width - m_width) / 2) : 0;
        intTop = (screen.height) ? ((screen.height - m_height) / 2) : 0;

        // Open the window.
        winLookup = window.open('', 'winLookup','scrollbars=no,resizable=yes,toolbar='+(showToolbar?'yes':'no')+',height=' + m_height + ',width=' + m_width + ',top=' + intTop + ',left=' + intLeft);
        checkPopup(m_url, m_title);

        // Set the window opener.
        if ((document.window != null) && (!winLookup.opener))
            winLookup.opener = document.window;

        // Set the focus.
        if (winLookup.focus)            
            winLookup.focus();
    }

    function checkPopup(m_url, m_title) {     
        if(winLookup.document) { 
            winLookup.document.write('<html><head><title>' + m_title + '</title></head><body height="100%" width="100%"><embed src="' +m_url + '" type="application/pdf" height="100%" width="100%" /></body></html>');
        } else { 
            // if not loaded yet
            setTimeout(checkPopup(m_url, m_title), 10); // check in another 10ms
        }
    }
