使用 AngularJS 解析 JSON 响应的问题 [英] Problems parsing a JSON response using AngularJS
问题描述
我是 AngularJS 的新手,在解析 json 响应时遇到问题.这是我使用的 HTML 代码:
<头><script src="@routes.Assets.at("javascripts/angular.min.js")" type="text/javascript"</script><script src="@routes.Assets.at("javascripts/carLibrary.js")" type="text/javascript"></script>头部><身体><div ng-controller="CarCtrl"><ul><li ng-repeat="汽车中的汽车">{{车名}}<p>{{car.speed}}</p><小时><p>{{响应}}</p>
</html>
这是使用 AngularJS 的 Javascript 代码:
function CarCtrl($scope, $http) {$scope.getAllCars = 函数 () {$scope.url = 'getAllCars';$http.get($scope.url).success(function (data, status) {$scope.response = 数据;var carFromServer = JSON.parse(data);$scope.cars = carsFromServer.allCars;}).错误(函数(数据,状态){$scope.response = '请求失败';});}$scope.getAllCars();}
HTML 显示变量 $scope.response 和服务器返回的 JSON,但它没有在顶部的列表中显示任何内容.JSON 格式完美,但 $scope.cars 变量似乎始终为空.
我做错了什么?
非常感谢,

$http.get 将为您解析 json.您不需要自己解析它.
$scope.cars = data.allCars;
I am new using AngularJS and I am having an issue parsing a json response. This is the HTML code I am using:
<!DOCTYPE html>
<html ng-app>
<head>
<script src="@routes.Assets.at("javascripts/angular.min.js")" type="text/javascript"</script>
<script src="@routes.Assets.at("javascripts/carLibrary.js")" type="text/javascript"></script>
</head>
<body>
<div ng-controller="CarCtrl">
<ul>
<li ng-repeat="car in cars">
{{car.name}}
<p>{{car.speed}}</p>
</li>
</ul>
<hr>
<p>{{response}}</p>
</div>
</body>
</html>
And this is the Javascript code using AngularJS:
function CarCtrl($scope, $http) {
$scope.getAllCars = function () {
$scope.url = 'getAllCars';
$http.get($scope.url).success(function (data, status) {
$scope.response = data;
var carsFromServer = JSON.parse(data);
$scope.cars = carsFromServer.allCars;
}).error(function (data, status) {
$scope.response = 'Request failed';
});
}
$scope.getAllCars();
}
The HTML is showing the variable $scope.response with the JSON returned by the server, but it is not showing anything in the list at the top. The JSON is perfectly formatted, however $scope.cars variable seems to be always empty.
What am I doing wrong?
Many thanks,

$http.get will parse the json for you. You do not need to parse it yourself.
$scope.cars = data.allCars;
