                 if(xmlHttp.readyState == 4 || xmlHttp.readyState == 'complete'){
                    if(xmlHttp.status == 200){
                          var response = xmlHttp.responseText;
                          if(response == "true") 
                            alert("设置成功！");
                            document.title = document.getElementById("ctitle").value; 
                            //关闭模式窗体 
                            dressUpCloseSeo();
                            else
                              alert("设置失败!");
                    }else
                    {
                        alert("设置失败，请稍候再试!");   
                         window.status = "服务器出错";
                    }
                 }
                 else
                 {
                     //打开模式窗体
                     showmodaldialog();
                     window.status = "正在提交设置……";
                 }
            };
