фрагмент кода js, чтобы открыть всплывающее окно

Ничего особенного, просто фрагмент кода JavaScript, чтобы открыть всплывающее окно.

W = window,
    D = document;

    //set the window to widgets dimensions
    var winH = 400, //allow for window padding and header
        winW = 400,
        winT = 400,
        winL = 400;

    //set the content
    var windowName = 'Widget', // should not include space for IE
        path = W.location.path,
        windowOptions = 'location=0,status=0,toolbar=0,dependent=1,resizable=1,menubar=0,screenX=' + winL + ',screenY=' + winT + ',width=' + winW + ',height=' + winH,
        that = this;
   
    //note path needs to be in the same domain...

    //open the window
    that._Window = window.open(path, windowName, windowOptions);
    that._Interval = window.setInterval(function () {
        if (that._Window.closed) {
            window.clearInterval(that._Interval);
            //code to run when window is closed

        }
    }, 1000);
