After trying what this question ask, I'm asking again how to retrieve data from web using AngularJS in the Ionic framework.
Basically, I do what the answer says:
.factory('Advices', function($http) {
var advices = null;
$http.get('http://myurl.myext/myfile.json').success(function (data) {
advices = data;
}).error(function(error) {
console.log('error'); //even if there i print the error it prints nothing
});
//etcetera
How can I rescue that file from my server?
Please try to following code
var app = angular.module('myApp', ['ionic']);
app.controller('mainInfoFactory', ['$scope', '$http', function($scope,$http) {
$http.get("http://myurl.myext/myfile.json")
.success(function (response)
{
$scope.advices = response;
})
.error(function(data) {
alert("ERROR");
});
}]);
Here myAPP and mainInfoFactory are AngularJS application name and controller respectively.
For example : ng-app="myApp" ng-controller="mainInfoFactory"

I'm trying to learn AngularJS and need some help. I'm using version 1.4.9 and I'm trying to create a service that will get JSON from a server but I'm getting the following error: "serviceName is not defined"
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
Here is my service:
app.service('serviceName', function ($http, $q) {
var url= "myURL";
function getData() {
return $http.get(url);
}
return {
getData: getData,
}
}
);
Here is my controller:
app.controller("myController", function ($scope, $http) {
serviceName.getData().then(function (response) {
$scope.myField = response.data;
});
});
You need to inject your service into the controller, like this:
app.controller("myController", function ($scope, serviceName) {
serviceName.getData().then(function (response) {
$scope.myField = response.data;
});
});
And you do not need $http, because that's used in the service ;)
I want to fetch data from JSON file which is on my local machine. But I am not able to get the data. It is showing some cross domain error for $http.
Here is my code.
angular.module('myApp',[])
.controller('myCtrl', function ($scope, webtest) {
webtest.fetch().then(function (data) {
$scope.accounttype = data;
})
});
.factory('webtest', function($q, $timeout, $http) {
var Webtest = {
fetch: function(callback) {
return $timeout(function() {
return $http.get('webtest.json')
.then(function(response) {
return response.data;
});
}, 30);
}
};
return Webtest;
});
Anyone please help me how to display data from local JSON file?
Thanks in Advance.
It's very simple like
$http.get('phones/phones.json').then(function(response) {
$scope.phones = response.data;
});

Don't you have an error message like "$http: is not defined" ?
I tried with a controller, this is working :
var ngApp = angular.module("ngApp", []);
ngApp.controller('myController', ['$http', function($http){
var thisCtrl = this;
this.getData = function () {
this.route = 'webtest.json';
$http.get(thisCtrl.route)
.success(function(data){
console.log(data);
})
.error(function(data){
console.log("Error getting data from " + thisCtrl.route);
});
}
}]);
If you haven't, use web developer tools (Ctrl+Shift+I in firefox).
If you haven't already done so. Try setting up a crossdomain policy for your application.
do you know what I am doing wrong? I want to read data from my json-file but i got the error that it can´t read the property getData.
myApp.service('jsonDataService', function ($http) {
this.getData = function () {
return $http({
method: 'GET',
url: '/jsonData/Stations.json'
});
}
});
controller:
myApp.controller('IndexController', ['$scope', function ($scope, jsonDataService) {
jsonDataService.getData().then(function (msg) {
$scope.msg = msg;
console.log(msg);
});
}]);
I am using ng in Visual studio in a mvc project.
path json-file: " Visual Studio 2015\Projects\Test\WebApplication\Scripts\jsonData\Stations.json"
In the controller code which you have shared, you have not injected 'jsonDataService' service properly.
It should be:
myApp.controller('IndexController', ['$scope', 'jsonDataService', function ($scope, jsonDataService) {
jsonDataService.getData().then(function (msg) {
$scope.msg = msg;
console.log(msg);
});
}]);
I'm developing my first AngularJS app using the Google Docs API to pass it JSON data.
This is an example of the factory I'm using:
app.factory('Data', ['$http', 'apiKeys', function($http, apiKeys){
var googleDocs = 'https://spreadsheets.google.com/feeds/list/';
return {
news:function () {
return $http.get(googleDocs + apiKeys.googleDoc +'/1/public/values?alt=json', {cache: true});
},
updates:function () {
return $http.get(googleDocs + apiKeys.googleDoc +'/2/public/values?alt=json', {cache: true});
},
docs:function () {
return $http.get(googleDocs + apiKeys.googleDoc +'/3/public/values?alt=json', {cache: true});
}
}]);
I wanted to clean up a bit the code and decided to use services instead of making the calls in the controller itself. It works normally, but it's a pain in the ass the fact that I still need to write long $scopes because of the structure of the Google API. This is how I get the values in the controller:
app.controller('homeCt', ['$scope', 'Data', function ($scope, Data){
Data.news().success(function (data) {
$scope.totalNews = data.feed.entry.length;
});
}]);
Is there a way that I can set the factory service to pass me the data just using:
$scope.totalNews = Data.news()
Or at least removing the 'feed.entry'?
Data.news().success(function (data) {
$scope.totalNews = data.length;
});
Thank you very much!
example of service - resolve the success with the data you want
app.service('Data', ['$http', 'apiKeys', function($http, apiKeys){
var googleDocs = 'https://spreadsheets.google.com/feeds/list/';
this.news =function(){
return $http.get(googleDocs + apiKeys.googleDoc +'/1/public/values? alt=json', {cache: true})
.then(function(data){
return data.feed.entry.length;
});
}
}]);
the controller - since you already resolved the data in service hence..
app.controller('homeCt', ['$scope', 'Data', function ($scope, Data){
Data.news().then(function (data) {
$scope.totalNews = data;
});
}]);
working example
var app = angular.module('app', ['ionic'])
.service('Data', ['$http',
function($http) {
var googleDocs = 'https://spreadsheets.google.com/feeds/list/1aC1lUSxKatfxMKEy1erKDSAKgijSWOh77FDvKWhpwfg/1/public/values?alt=json';
this.news = function() {
return $http.get(googleDocs, {
cache: true
}).then(function(res) {
return res.data.feed.entry;
});
}
}
])
.controller('homeCt', ['$scope', 'Data',
function($scope, Data) {
Data.news().then(function(data) {
console.log(data);
})
}
]);
I'll give you a way of doing it, a way that I don't recommend at all (a service should not handle the scope), but for me it is the only way you have if you don't want to destroy the "async" of your ajax call :
app.factory('Data', ['$http', 'apiKeys', function($http, apiKeys){
var googleDocs = 'https://spreadsheets.google.com/feeds/list/';
return {
news:news,
updates: updates,
[...]
}
function news(scopeValue) {
$http.get(googleDocs + apiKeys.googleDoc +'/1/public/values?alt=json', {cache: true}).success(function(data){
scopeValue = data;
});
}]);
and then, call it that way in your controller :
Data.news($scope.totalNews);
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);
});
});
