Question

我有用户列表，我会向用户显示。用户有未完成的消息而没有写入用餐列表，我想在主http.get请求中制作http.get以获取所需信息，但我的问题是它异步工作，因此未读消息和周值不会改变。我该怎么做。提前致谢

$http.get('http://example.com/users').success(function(response){         
            var data=response;
            if(data==null || data.length<=0){
                return;
            }
            var date2 = new Date();

            var users=[];

            for(var i=0;i<data.length;i++){
                var diffDays=0;

                if(data[i].uyelikBaslangicTarihi=="0"){                             
                    continue;
                }
                var from = data[i].uyelikBaslangicTarihi.substring(0,10).split("/");                    
                var date1 = new Date(from[2], (from[1] - 1), from[0]);                  
                var timeDiff = Math.abs(date2.getTime() - date1.getTime());
                diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24)); 
                if(diffDays>28 || diffDays<0){                              
                    continue;
                }
                var week=diffDays/7;
                week=parseInt(week);
                if(diffDays/7>0)
                    week++;                     
                if(week!=0)
                    week--;
                var unloadweek=week+1;
                var unreadmessage=0;


                $http.get('http://example.com/menus?userId=' + data[i]._id + '&haftaSayisi=' + week).success(function(response){        
                    if(response==null || response.length==0){unloadweek= "";}
                    else{unloadweek= week;}          
                });
                $http.get('http://example.com/sorus?userId=' + data[i]._id + '&okundu=0').success(function(response){   
                    console.log(response);
                    if(response==null){ unreadmessage= 0;}
                    else{unreadmessage = response.length;}       
                });
                var color="white"       

                var gender='mars'   

                if(data[i].cinsiyet=="Kadın")
                    gender='venus';
                var user={
                    id:data[i]._id,
                    name:data[i].ad,
                    gender:gender,
                    weight:data[i].kilo,
                    height:data[i].boy,
                    birthday:data[i].dogum_tarihi,
                    email:data[i].email,

                if(data[i].uyelikBaslangicTarihi!="" && data[i].uyelikBaslangicTarihi!="0" && data[i].rol!="admin")
                    users.push(user);

            }
            $scope.customers=users;

您需要正确链接您的http请求和承诺。请参阅文档（见下文）。

另外，请尊重该上下文中变量的范围 - unloadweek变量在get之前定义，然后在下一个$ http.get resolve函数中使用 - 以及for循环中的所有变量。

不确定您的代码结构是否也存在问题:)建议改进之处; - ）
