I have a problem which should be wasy to solve, but I just cant figure out what I am doing wrong. I receive data through an $http request.
alert(data)
gives me object object
alert(data.response)
gives me {"id":"123456","post_id":"12345"}
alert (data.response.id)
gives me undefined
My question: I want to get the ID. Why does the last expression give me undefined and not the ID? Do I have to transform the data in some way?
I am thankful for any hints!
It looks like your data.response is a string.
You use angular.fromJson to convert it to object ie :
$scope.temp = angular.fromJson($scope.data.response);
please see working demo below
var app = angular.module('app', []);
app.controller('firstCtrl', function($scope){
$scope.data = {
response:'{"id":"123456","post_id":"12345"}'
};
alert($scope.data);
alert($scope.data.response);
alert($scope.data.response.id);
$scope.temp = angular.fromJson($scope.data.response);
alert($scope.temp.id);
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app">
<div ng-controller="firstCtrl">
</div>
</body>
var app = angular.module('myApp', []);
app.controller('list_employeesController', function($scope, $http) {
// email = $scope.email;
// psw = $scope.psw;
$http({
method: "GET",
url: "http://localhost:3000/employees",
params: {}
}).then(function mySuccess(response) {
// a string, or an object, carrying the response from the server.
$scope.myRes = response.data;
$scope.statuscode = response.status;
}, function myError(response) {
$scope.myRes = response.statusText;
});
});
Simply Here myRes has the response data to this request.
And we can display it in HTML file using expression syntax in angular
<h2> Result : {{myRes}} </h2>
var app = angular.module('myApp', []);
app.controller('student_Controller', function($scope, $http) {
$http({
method: "GET",
url: "http://localhost:8000/employees",
}).then(function mySuccess(response) {
$scope.res= response.data;
$scope.statuscode = response.status;
}, function myError(response) {
console.log("response--"+response);
});
});
data.responseis a string, not an Object. Otherwise similarly toalert(data)you would have got[object Object].
