Prerequisites: Angularjs tutorial 5

In today's blog, we will look at how to call a service from your AngularJS application. For the sake of simplicity, instead of creating a REST service, I am utilizing a service from w3schools:

You can as well write your complex service and expose that to be used in your Angular App.
Angular has exposed a library called as $http: The $http service is a core Angular service that facilitates communication with the remote HTTP servers via the browser’s XMLHttpRequest object or via JSONP.

Methods that are available (source Angular website):

We will be using a simple get for our demo purpose.

Our JS file would look as below:

var Namespace = angular.module('Namespace', []);

Namespace.controller('StoreController', function ($http, $log, $q, $scope) {

    $ = "Aditya S";
    $scope.bookarray = [];
    $scope.greeting = null;
    $scope.servicebook = null;

       success(function (data) {
           $scope.greeting = data;

From the above, we are using a $http.get to retrieve the data from the service which would be available in “data”. We could then parse this and perform further operations or for simplicity, I have filled in data in greeting.

Our html page would look as below:

<!DOCTYPE html>
<html lang="en" ng-app="Namespace">

    <meta charset="utf-8">
    <title>Book Cart</title>
    	<link rel="stylesheet" type="text/css" href="css/templates.css" />
    <script src="">

    <script src="javascript/app.js"></script>

<body ng-model="Namespace" ng-controller="StoreController">

Hello {{name}}
<h1>Welcome to my book store</h1>
<div style="width: 100%;       overflow: scroll;">
<div ng-repeat="data in greeting.records">

The Name is <b>{{data.Name}}</b>

The Country is <b>{{data.Country}}</b></div>


I am using ng-repeat to parse through the results and display it. The output would be as below. Further, we would look how to create a mobile Application using Ionic in our further blogs.
