AngularJS AJAX – $http

If you are interested to learn about the AngularJS Filters

$http is an AngularJS service for reading data from remote servers. AngularJS provides $http control which works as a service to read data from the server. The server makes a database call to get the desired records. AngularJS needs data in JSON format.

AngularJS $http

The AngularJS $http service makes a request to the server, and returns a response. AngularJS provides a $http service for reading data and remote servers. It is used to retrieve the desired records from a server.


Make a simple request to the server, and display the result in a header:

div ng-app="myApp" ng-controller="myCtrl"> ;
p>Today's welcome message is:
/p><br> ;h1>{{myWelcome}};
script><br>var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {<br>  $http.get("welcome.htm")<br>  .then(function(response) {<br>    $scope.myWelcome =;<br>  });

What is $HTTP service?

The $http service is a core AngularJS service that facilitates communication with the remote HTTP servers via the browser’s XMLHttpRequest object or via JSONP. For unit testing applications that use $http service, see $httpBackend mock


The example above uses the .get method of the $http service. The .get method is a shortcut method of the $http service. There are several shortcut methods:

  • .delete()
  • .get()
  • .head()
  • .jsonp()
  • .patch()
  • .post()
  • .put()

The methods above are all shortcuts of calling the $http service:

chapter: Chapter-9 / AngularJS Book


var app = angular.module('myApp', []);
<br>app.controller('myCtrl', function;
then(function mySuccess(response)    $scope.myWelcome =;},
 function myError(response)  $scope.myWelcome = response.statusText; 

The example above executes the $http service with an object as an argument. The object is specifying the HTTP method, the url, what to do on success, and what to do on failure.


The response from the server is an object with these properties:

  • .config the object used to generate the request.
  • .data a string, or an object, carrying the response from the server.
  • .headers a function to use to get header information.
  • .status a number defining the HTTP status.
  • .status Text a string defining the HTTP status.


var app = angular.module('myApp', []);
app.controller('myCtrl', function;
then(function(response) {<br>    
$scope.content =;
$scope.statuscode = response.status;    $scope.statustext = response.statusText;

To handle errors, add one more functions to the .then method:


var app = angular.module('myApp', []);
<br>app.controller('myCtrl', function
then(function(response)  // First function handles success    $scope.content =; function(response)    // Second function handles error< $scope.content = "Something went wrong";

How can you make Ajax call using AngularJS?

Make AJAX Call and Return JSON Using AngularJS

<script> var myapp = angular. 
module('myApp', []);
myapp. controller('control', function ($scope, $http)
 {  var call = "WebService1. asmx/HelloWorld";
 $http. post(call). success(function (response)
 { $scope. value = response; }) . 
error(function (error) {


The data you get from the response is expected to be in JSON format. JSON is a great way of transporting data, and it is easy to use within AngularJS, or any other JavaScript. Example: On the server we have a file that returns a JSON object containing 15 customers, all wrapped in array called records.


The ng-repeat directive is perfect for looping through an array:

div ng-app="myApp" ng-controller="customersCtrl">;
li ng-repeat="x in myData">    {{ x.Name + ', ' + x.Country }} ;
/li>  ul> /div> ;
script> var app = angular.module('myApp', []);
app.controller('customersCtrl', function  get("customers.php").
then(function(response) myData =;

      div ng-app = "" ng-controller = "studentController";
              th ;Name;/th;
              th;Roll No;/th;
            tr ng-repeat = "student in students;
               {{ student.Name }}/td;
              {{ student.RollNo }}
              {{ student.Percentage }}
         function studentController($scope,$http) {
            var url = "/data.txt";

            $http.get(url).then( function(response) {
               $scope.students =;
      script src = ""&gt;


To execute this example, you need to deploy testAngularJS.htm and data.txt file to a web server. Open the file testAngularJS.htm using the URL of your server in a web browser and see the result.
