  7. 7. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (1/7) ❖ We need a blank HTML template ❖ And a clean folder structure: ■ app/ ■ css/ ■ js/ ■ index.html
  8. 8. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (2/7) <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>AngularJS Workshop</title> <link media="all" rel="stylesheet" href="css/style.css"> </head> <body> <script src="js/jquery-2.1.1.min.js"></script> <script src="js/angularjs/angular.min.js"></script> <!-- AngularJS App --> <script src="app/app.js"></script> </body> </html> A blank HTML template
  9. 9. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (3/7) ❖ Container for AngularJS magic ❖ You may include other modules ➢ Don’t invent the wheel twice ➢ Just reuse other modules in your applications ❖ A module is the beginning of all AngularJS projects A module for the application
  10. 10. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (4/7) ❖ In app/app.js we declare our first module: A module for the application // declares a module var app = angular.module('myFirstApp', []); app.controller(‘MyFirstController’, ...); // also declares a module angular.module('mySecondApp', ['myFirstApp']); angular.module('mySecondApp').controller(...);
  11. 11. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (5/7) ❖ This happens with the directive ng-app: Lets introduce the HTML to our new app <body ng-app="myFirstApp"> <!-- Script includes ... --> <script src="app/app.js"></script> </body> ❖ It is possible to use several apps seperately on one page
  12. 12. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (6/7) ❖ Created a blank HTML template ➢ Included jQuery, AngularJS and our first module ❖ Declared first module in app.js ❖ Paired <body> with myFirstApp ➢ by using ng-app directive Summary
  13. 13. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The very first steps (7/7) ❖ An awesome blank site, ready for AngularJS magic ;-) Result

  16. 16. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (1/7) ❖ Everything in your DOM may be a directive: ➢ Elements (<ng-include></ng-include) ➢ Classes (class="ng-include: data;") ➢ Attributes (<b ng-include="data">) ➢ Comments (<!-- directive: ng-include data -->) ❖ Directives attach custom behavior to those elements or transform them What the $%&!% are directives?!
  17. 17. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (2/7) ❖ AngularJS provides plenty of its own directives: AngularJS provided directives ❖ ngApp ❖ ngBind ❖ ngBlur ❖ ngChange ❖ ngChecked ❖ ngClass ❖ ngClick ❖ ngInlcude ❖ ngModel ❖ ngPluralize ❖ ngRepeat ❖ ngShow ❖ ngSrc ❖ ...
  18. 18. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (3/7) ❖ Directive ngModel: ➢ <input ng-model="foo"> ➢ <input data-ng:model="foo"> ➢ <input data-ng-model="foo"> ➢ <input ng:model="foo"> ➢ <input ng_model="foo"> ➢ <input x-ng-model="foo"> ❖ Might be necessary for html/xhtml validation reasons Different syntax available
  19. 19. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (4/7) ❖ Let’s take the HTML template we have prepared and add: Simple example of Angular’s directives (1/2) <input type="text" ng-model="name"> <h1 ng-show="name" ng-class="{red: name=='Armin'}"> Hello, {{name}}! </h1> ❖ name is a new scope variable ➢ ng-model binds the value of <input> to this variable ➢ {{name}} expression outputs the variable
  20. 20. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (5/7) ❖ We also add a button to set name: Simple example of Angular’s directives (2/2) <button ng-click="name='Penelope'">Click me</button> ❖ Clicking the button will set the scope variable name to “Penelope”. This affects: ➢ The value of <input>, because it is two-way data bound to variable name ➢ And the {{name}} expression, which outputs the value
  21. 21. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (6/7) ❖ Allmost every DOM element may be a directive ❖ We have learned some of Angular’s directives: ➢ ng-model, ng-show, ng-class and ng-click ❖ We have heard about scope variables ❖ We know of double curley expressions to output {{variables}} Summary
  22. 22. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Directives (7/7) ❖ A dynamic application without writing one line of javascript code Result

  28. 28. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (4/14) ❖ Controllers create new child scopes ❖ May contain: ➢ Scope variables ➢ Scope functions ❖ Should contain only business logic ➢ Set up the initial state of $scope object ➢ Add behavior to the $scope object Controllers
  29. 29. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (5/14) ❖ Create file app/Controllers/Superheroic.js with content: Create the first controller app.controller('SuperheroicController', ['$scope', function($scope){ $scope.name = 'Tom'; }]); ❖ Expression {{name}} inside of controller’s scope will always return “Tom”
  30. 30. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (6/14) ❖ May also contain functions: Controller’s $scope app.controller('SuperheroicController', ['$scope', function($scope){ $scope.add = function(a, b) { return a + b; } }]); ❖ Expressions may also output functions and pass parameters: <h1>1 plus 2 equals <em>{{add(1,2)}}</em></h1>
  31. 31. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (7/14) ❖ Change events for scope variables ➢ Get fired when value of defined scope variable changes Watches $scope.$watch('name', function(newValue, oldValue){ alert('New value: ' + newValue); }, false); ❖ Instead of 'name' you may also use a function ❖ Can also watch deep objects (set third param to true)
  32. 32. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (8/14) ❖ Double curley braces syntax ➢ Contains basically javascript ➢ Accesses scope variables and scope functions Expressions ❖ Examples: a. {{a+b}} b. {{alert('Does this work?')}} c. {{'Just outputs this string'}} d. {{a ? a : '??'}} e. {{user.name}}
  33. 33. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (9/14) Two-Way Data Binding
  34. 34. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (10/14) Two-Way data binding example (with one user) Model User { id: 1, name: 'Vieweg', firstName: 'Armin', image: 'armin.png' } <div class="user"> <img ng-src="path/to/{{user.image}}"> <h2> {{user.name}}, {{user.firstName}} </h2> </div>
  35. 35. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (11/14) ❖ Scope variables may also contain arrays of objects ❖ To work with them use the ng-repeat directive Two-Way data binding example (with several users) <div class="user"> <img ng-src="path/to/{{user.image}}"> <h2>{{user.name}}, {{user.firstName}}</h2> </div> <div class="entry" ng-repeat="user in users"> </div> $scope.users = [ { name: '...', firstName: '' }, {...} ];
  36. 36. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (12/14) ❖ Very helpful extension for Google Chrome (Link) ❖ Shows and highlights scopes and its variables Google Chrome: AngularJS Batarang
  37. 37. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS The Big Picture (13/14) ❖ AngularJS works with scopes ➢ Scopes inherit their variables/functions to child-scopes ➢ At the very top there exists one $rootScope ➢ $scope.$watch allows us to react on changes of variables ❖ Expressions work in scope context ➢ They check all scopes up to $rootScope for requested variable or function ❖ Two-Way Data Binding does very much work for us Summary

  48. 48. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Services & Factories ❖ Reuseable component ❖ A service/factory in Angular is: ➢ Lazy instantiated ➢ Singleton ❖ Angular offers several useful services ➢ They are prepended with $ ➢ Do not use $ in your own services Substitutable objects that are wired together using DI
  49. 49. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Services & Factories ❖ $http - For ajax requests ❖ $interval and $timeout - Repeats and delays ❖ $rootScope - Very top scope of application ❖ $location - URL and its parts of current site ❖ $window - Wrapper of global window. Useful for tests. Selection of useful services provided by Angular
  50. 50. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Services & Factories Usage example (with Dependency Injection) app.controller('SuperheroicController', ['$scope', '$http', function($scope, $http){ $scope.getTypo3Releases = function() { $http({ method: 'GET', url: 'http://get.typo3.org/json' }).success(function(response){ // ... }); }; }]);
  51. 51. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Services & Factories Writing our first factory app.factory('Typo3Releases', ['$http', function($http){ var getUrl = 'http://get.typo3.org/json'; var typo3ReleasesService = {}; typo3ReleasesService.get = function(callbackSuccess) { $http({ method: 'GET', url: getUrl }).success(callbackSuccess); }; return typo3ReleasesService; }]);
  52. 52. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Services & Factories Inject and call our first factory app.controller('SuperheroicController', ['$scope', 'Typo3Releases', function($scope, Typo3Releases){ $scope.getTypo3Releases = function() { Typo3Releases.get(function(response){ // ... }); }; }]);
  53. 53. 20th June 2014, Armin Rüdiger Vieweg (@ArminVieweg) Getting started with superheroic JavaScript library AngularJS Services & Factories Service and factory syntax compared app.service('Typo3Releases', ['$http', function($http){ this.get = function(){ // ... } }]); app.factory('Typo3Releases', ['$http', function($http){ var typo3ReleasesService = {}; typo3ReleasesService.get = function() { // ... }; return typo3ReleasesService; }]); Both have the same call: Typo3Releases.get();
