You can obtain the reference of child window simply by following trick.

newWin = window.open("", "child_window_name", "width=...");
if (newWin.location.href === "about:blank") {
    newWin = window.open("a.html", "child_window_name", "width=...");
} else {
    // We've already obtained the reference.
    // However, IE and FireFox won't put focus on an already opened window.
    // So we have to do that explicitly:
    newWin.focus();
}

Note you must have a fixed child window name to make this trick works.
