Question

我有一个多维数组，用于在表中创建表单字段，添加不在初始数组中的其他字段。当我输入数据后打印出此表单字段的值时，我得到了未定义。

这是数组

$scope.benefits = {
                "Emergency services": [
                    "Emergency room care",
                    "Ambulance service",
                    "Urgent care centers/facilities"
                ],
                "Laboratory services": [
                    "Lab tests & X-ray services",
                    "Imaging/diagnostics (e.g.,  MRI, CT scan, PET scan"
                ],
            };

更改数组声明。见Plunkr。 https://plnkr.co/edit/kVgKIM?p=preview

		(function() {
			'use strict';

			angular.module('testBenefits', ['ngRoute'])
			.controller('benefitsCtrl', ['$scope', function ($scope) {

				$scope.benefits = {
					"Emergency services": {
				        "Emergency room care":{
				          'name':'',
				          'limit':'',
				          'dlimit':''
				        },
				        "Ambulance service":{
				          'name':'',
				          'limit':'',
				          'dlimit':''
				        },
				        "Urgent care centers/facilities":{
				          'name':'',
				          'limit':'',
				          'dlimit':''
				        }
				    },
				    "Laboratory services": {
				        "Lab tests & X-ray services":{
				          'name':'',
				          'limit':'',
				          'dlimit':''
				        },
				        "Imaging/diagnostics (e.g.,  MRI, CT scan, PET scan":{
				          'name':'',
				          'limit':'',
				          'dlimit':''
				        }
				    },
				};

				$scope.showItems = function() {
					console.log($scope.benefits);
				};
				
			}]);

		})();

ng-model从数组重命名时未定义的值
