Angularjs：我想将响应对象的结果打印到$ http get response中的各个元素中。请参阅下面的代码

Question

这是json：

 {"item":{"id":"3","firstName":"Eugene","lastName":"Lee","managerId":"1","title":"CFO","department":"Accounting","city":"Boston, MA","officePhone":"617-000-0003","cellPhone":"781-000-0003","email":"elee@fakemail.com","picture":"eugene_lee.jpg","managerFirstName":"James","managerLastName":"King","reportCount":"0"}}

现在有了$ http获取请求，我试图将响应作为

{"id":"3","firstName":"Eugene","lastName":"Lee","managerId":"1","title":"CFO","department":"Accounting","city":"Boston, MA","officePhone":"617-000-0003","cellPhone":"781-000-0003","email":"elee@fakemail.com","picture":"eugene_lee.jpg","managerFirstName":"James","managerLastName":"King","reportCount":"0"} 

使用以下代码

.controller('Detailing', function($scope, $http, $stateParams) {
$http.get("//localhost/directory/services/getemployee.php?id="+$stateParams.id)
.then(function(response) {
    $scope.employee = response.data.item;
})
});

它给了我未定义的。

Answer 1

.controller('Detailing', function($scope, $http, $stateParams) {
 $http.get("//localhost/directory/services/getemployee.php?id="+$stateParams.id)
.then(function(response) {
   $scope.employee = response.data; // Without item key
 })
});

JSON不包含item密钥。因此给出了这个错误。试试上面的

Answer 2

一些观察结果：

• 您的回复是JSON string而不是JSON object。因此，当您尝试从JSON string获取项目对象时，它会为您提供undefined。

• 您从$http.get请求获得的回复中没有项目对象。

解决方案：

如果您获得的回复是JSON.parse()，请使用JSON string将JSON字符串转换为JSON对象。

var obj = '{"item":{"id":"3","firstName":"Eugene","lastName":"Lee","managerId":"1","title":"CFO","department":"Accounting","city":"Boston, MA","officePhone":"617-000-0003","cellPhone":"781-000-0003","email":"elee@fakemail.com","picture":"eugene_lee.jpg","managerFirstName":"James","managerLastName":"King","reportCount":"0"}}';

var data = JSON.parse(obj);
console.log(data.item);
