function postOpenWindow(URL, PARAMS, target) {
                    if(target == null) target = "_blank";
                    var temp_form = document.createElement("form");
                    temp_form.action = URL;
                    temp_form.target = target;
                    temp_form.method = "post";
                    temp_form.style.display = "none";
                    for(var x in PARAMS) {
                        var opt = document.createElement("textarea");
                        opt.name = x;
                        opt.value = PARAMS[x];
                        temp_form.appendChild(opt);
                    }
                    document.body.appendChild(temp_form);
                    temp_form.submit();
                    document.body.removeChild(temp_form);
                }
                postOpenWindow("http://localhost:8080/111.html", {}, "_blank");
