script.js

for(var i = 0;i<$scope.data_acc_lv.length;i++)
        {
            var input3 = {
                "_id": $scope.accLvID + i,
                "acc_id":$scope.accLvID,
                "name": $scope.data_acc_lv[i].names,
                "read": $scope.data_acc_lv[i].read,
                "execute": $scope.data_acc_lv[i].execute,
            }
            $http.post("http://localhost:1234/access_menu",input3)
            .success(function(res){
                if(res.error == 0)
                {

                }

            });
        } 

script.js

app.post('/access_menu',function(req,res){
    var IDMenu = req.body._id;
    var Forein = req.body.acc_id;
    var Name = req.body.name;
    var Read = req.body.read;
    var Execute = req.body.execute;

    var data = {"error":1,"Access_menu":""};
    if(!!Name && !!Read && !!Execute)
    {
        db.collection("access_menu").insert({_id:IDMenu,acc_id:Forein,name:Name,read:Read,execute:Execute},function(err,req){
            if(!!err)
            {
                data['Acess_menu'] = "input error";
            }
            else
            {
                data['error'] = 0;
                data['Access_menu'] = "input berhasil"
            }
            res.json(data);
        });
        data = {"error":1,"Access_menu":""};
    }
});

so I trying to input data from table to database but I always got the value from the last index (all previous value replace by the last index value), so what the cause the problem. Thank you
