Reading a JSON File With Ionic Framework & Angular Js

Introduction

AngularJS is perfect for Single Page Applications (SPAs).
AngularJS extends HTML attributes with Directives, and binds data to HTML with Expressions.
$http is an AngularJS service for reading data from remote servers.

1.Create the project

ionic start Test blank

2. JSON File to read name as Customers_JSON.json

[ { "Name" : "Santosh Shinde", "City" : "Abc_Sangamner", "Country" : "India" }, { "Name" : "Bhausaheb Sangale", "City" : "Sinnar", "Country" : "India" }, { "Name" : "Derik Taylor", "City" : "Indianapolis", "Country" : "USA" } ]

3.Write controller to get JSON data controllerJs.js

var app = angular.module('myApp', ['ionic']); app.controller('customersController', ['$scope', '$http', function($scope,$http) { $http.get("http://myurl/json/Customers_JSON.json") .success(function (response) { $scope.names = response; }); }]);

The AngularJS application is defined by ng-app. The ng-controller directive names the controller object.The customersController function is a standard JavaScript object constructor.AngularJS will invoke customersController with a $scope and $http object.
$scope is the application object (the owner of application variables and functions).$http is an XMLHttpRequest object for requesting external data.$http.get() reads static JSON data from http://myurl/json/Customers_JSON.json.
If success, the controller creates a property (names) in the scope, with JSON data from the server.
4.To show json data on list index.html

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"> <title></title> <link href="lib/ionic/css/ionic.css" rel="stylesheet"> <link href="css/style.css" rel="stylesheet"> <!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above <link href="css/ionic.app.css" rel="stylesheet"> --> <!-- ionic/angularjs js --> <script src="lib/ionic/js/ionic.bundle.js"></script> <!-- cordova script (this will be a 404 during development) --> <script src="cordova.js"></script> <!-- your app's js --> <script src="js/controllerJs.js"></script> </head> <body ng-app="myApp" ng-controller="customersController"> <ion-pane> <ion-header-bar class="bar-stable"> <h1 class="title">Ionic Blank Starter</h1> </ion-header-bar> <ion-content> <ion-list> <ion-item ng-repeat="x in names|orderBy:'City'"> {{ x.Name + ', ' + x.Country+', '+x.City}} </ion-item> </ion-list> </ion-content> </ion-pane> </body> </html>

5.Build the Project

ionic build android

What exactly means MVW design pattern ?

What is a MVW framework? The abbreviation stands for 'Model - View - Whatever'.  Well there are many different JavaScript frameworks available , all invented for the same purpose. They all try to separate the presentation logic from the business logic where JavaScript holds the model and logic, and html the presentation layer. Quick overview : You can change the model without changing the view and vice-versa Unit testing is easy These are the core benefits of using such a framework. By separating presentation and business logic changes to the code are easier to implement and take less time. Another benefit is that code can be reused from a controller thus saving more time. Angularjs makes the code also shorter in comparison to other frameworks, which improves code stability. Less code means minor potential for bugs. For several years +AngularJS was closer to MVC (or rather one of its client-side variants), but over time and thanks to many refactorings...

Steps To Create Cordova Plugin

Introduction A plugin is a package of injected code that allows the Cordova webview within which the app renders to communicate with the native platform on which it runs. Plugins comprise a single JavaScript interface along with corresponding native code libraries for each supported platform. Due to following reason, we will go for plugin development To get the native capabilities of the device in the cordova based app Build the common functionality across the number of Cordova application(Reusability) Prerequisites For the creation of plugin you need to install plugman . npm install -g plugman Plugin Structure Decide Plugin ID & Name The plugin ID should be unique Plugin name should follow the convention “cordova.plugin.[your.plugin.name]” Create the structure Use the following command to create the plugin with plugin ID “cordova.plugin.test” and name “Test”. plugman create --name Test --...
