html - 获取 Angular js 中返回的 JSON 对象的值

Question

我是 Angular 和 Node.js 新手。

基本上，我有一个项目表，每行都有一个按钮单击。 如果我点击编辑按钮，详细信息应该出现在相应的文本框中进行编辑。

router.route('/contacts/getone/:pk')
    .get(function(req, res, next){
        pg.connect(connectionString, function(err, client, done) {
            //var id = {pk:req.body.pk};
            var contacts = [];
            console.log("get1");
            console.log(req.params.pk);
            var query = client.query("select * from contacts where pk=($1)", [req.params.pk]);
            query.on('row', function(row) {
                contacts.push(row);
               });
               query.on('end', function() {
                done();
                return res.json(contacts);
            });
        });
    });

这是我的 Angular Controller 代码。

$scope.editContact = function(id) {
        contact.getone(id)
        .success(function(data) {

                $scope.contactlist = data;
                //console.log("geone");
                //document.getElementById("fname").value = $scope.contactlist.firstname;
                //console.log("getall");
                //console.log($scope.contactlist.firstname);
                //console.log(data["firstname"]);
                $scope.formData.firstname = $scope.contactlist.firstname;
                $scope.formData.lastname = $scope.contactlist.lastname;
                $scope.formData.address = $scope.contactlist.address;
                $scope.formData.contact = $scope.contactlist.contact;
//                $scope.loading = false;
            });
    };

谁能告诉我如何访问我的node.js代码返回的数据中的值？我的 Angular 中的代码返回未定义的值，例如 $scope.contactlist.firstname 未定义。

这是我执行 console.log(data);

@Rayin Dabre ----这是我的 Controller 的代码。

angular.module('ContactsControl', [])

.controller('contactController', ['$scope', '$http', 'contact', function($scope, $http, contact) {
	$scope.formData = {};
	
	contact.get()

			.success(function(data) {
				console.log("getall");
				$scope.contactlist = data;
//				$scope.loading = false;
			});
	$scope.editContact = function(id) {
		contact.getone(id)
		.success(function(data) {

				$scope.contactlist = data;
				//console.log("geone");
				//document.getElementById("fname").value = $scope.contactlist.firstname;
				console.log(data);
				//console.log($scope.contactlist.firstname);
				//console.log(data["firstname"]);
				$scope.formData.firstname = $scope.contactlist.firstname;
				$scope.formData.lastname = $scope.contactlist.lastname;
				$scope.formData.address = $scope.contactlist.address;
				$scope.formData.contact = $scope.contactlist.contact;
//				$scope.loading = false;
			});
	};
