    //检测是否登录   
        var guest = user.guest()  
        guest.then(function(val){  
            if(val)  
            {  
                $.showPreloader('正在自动登录...');  
            var webview = plus.webview.create( "main.html", "main" );     
            webview.show();  
            var data = {  
                    list: ['文艺','博客', '摄影', '电影', '民谣', '旅行', '吉他']  
                };  
                var html = template('lottery_list', data);  
                $('#lottery_list_content').html(html)  
            $.hidePreloader();  
            }
