如何使用Angular js把一个嵌套对象放入数据库中?

How to PUT a nested object into the database using Angular js 1?

本文关键字：对象 嵌套 数据库 一个 js Angular 何使用      更新时间：2023-09-26

我是Angular JS 1的新手。在我的要求中，我试图使用API (PUT方法)将数据上传到mongoDB。但是我不确定如何定义一个嵌套的对象。在表单中，我有地址字段，它有两个嵌套对象permanent和postal。下面是便于理解的格式。

JSON数据:

   "address" : {
     "permanent" : {
       "line1" : "geisenheimer",
       "zip" : 14197, 
       "state" : "BW", 
       "Country" : "DE"
     },
     "postal" : {
       "line1" : "Sandwingert",
       "zip" : 69123, 
       "state" : "BW", 
       "Country" : "DE"
     }
   }

我想知道我在控制器中定义的地址是否正确。

index . html 

   <form class="form-horizontal">
                <div class="form-group" ng-class="{ 'has-error': form.name.$dirty && form.name.$error.required }">

                             $scope.permanent.zip = "";
                             $scope.permanent.state= "";

                        }
                        );                                                          

                }
     })
 })();

我不太明白你的问题。看来你的$scope.address已经按你想要的方式格式化了。

您应该能够只使用$scope.address变量，因为它绑定到您希望PUT的对象。

$http.put('https://student.herokuapp.com/user/personalInfo', $scope.address)

使用

Name : <input type="text" ng-model="name">
<button ng-click="submitFormAngular()">Calculate</button>

和

 var app = angular.module('formapp', []);
    app.controller('formctrl', function ($scope, $http) {
        $scope.name = 'MyName';
        $scope.submitFormAngular = function () {
            var name = $scope.name;
            var data = {};
            data.name = name;
            //var data = { 'id': 10 };
            var url = '/Home/AngularAjax';
            $http({
                method: 'PUT',
                url: url,
                data: data //forms user object
                //  headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).success(function (data) {
                console.log(data);
            });

        };
    });

            };
