var canclePath = 'http://appb.niwota.com/app_games/1_index.jsp';

//参数二：Form表单提交地址（包含“requestPath”参数）
var actionPath = 'http://www.niwota.com/user/login_page.jsp?requestPath=http://appb.niwota.com/app_games/loadGame.jsp?gameId=<%= gameId %>';

//参数三：登录窗口显示的提示信息
var message = '您现在还没有登录，不能继续玩小游戏了，请先登录。';

//参数四：从cookie中获取到的用户姓名
var userName = objJson.userName_cookie;

//参数五：用户注册来源
var sign = 'xiaoyouxi';

//方法调用
loginDialog(canclePath, actionPath, message, userName, sign);
