Question

的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)
                {

                }

            });
        }

的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":""};
    }
});

所以我尝试从表到数据库输入数据，但我总是得到最后一个索引的值（所有以前的值都替换为最后一个索引值），所以导致问题的原因。谢谢

Answer 1

var temp = [];
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,
          }
         temp.push(input3)
} 
$http.post("http://localhost:1234/access_menu",temp )
        .success(function(res){
            if(res.error == 0)
            {

            }

        });

为什么不只是格式化你的数组然后在帖子上发送整个数组然后在你的script.js中循环？

您可以将代码中的代码包装在一个立即调用的函数中

     (function( 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)
            {

            }

        });

      })(i);

希望这有帮助。
