    I see this question is somewhat old.

    However, arthur stated,

    for targetUrlVar being an internal resource (like a page belonging to my domain) it works.. but as soon as i wanted to used the .load() or myWindow.onload() with a targetUrlVar being an external page (such as www.yahoo.com or www.google.com ), it doesn't work any more... No alert is displayed..

    I think that the issue may be due to the targetUrlVar being external; the alert may be blocked to prevent cross-site scripting (aka XSS).

    $(document).ready(function() {
   //perform tasks, DOM is loaded
});

    Hope this helps.

    If you want to trigger the alert when the child window is open regardless of the state of the child window's DOM then this should work. I also provided a way to test this assumption.

    Create a test PHP script (or similar scripting language) with the following content:

    <html>
<head><title>test</title></head>
<body>
    <?php sleep(5); // Sleep to delay DOM from loading ?>

    Done sleeping...
</body>
</html>

    Then call this test page as your child window usingthe following javascript:

    win = window.open('test.php', 'test', 'width=300, height=400, x=800');
win.focus();
$(win.document).ready(function() {
    alert('Window is open');
});

    You'll notice that the alert() from the parent window fires before you see "Done sleeping..." appear in the child window.
