    More often than not you want to create a child window and want to capture its events. This example simply captures its close event.

    var childWindow = window.open("new.html");
    
        function doStuffOnUnload() {
            alert("Child Windows Closed!");
        }
    
        if (typeof childWindow.attachEvent != "undefined") {
            childWindow.attachEvent("onunload", doStuffOnUnload);
        } else if (typeof childWindow.addEventListener != "undefined") {
            childWindow.addEventListener("unload", doStuffOnUnload, false);
        }
