This lesson describes what is really happening when you use the angular
factory and how you can make your factories even more dynamic in creation.
This gets further into the internals of AngularJS by showing you how a factory is built dynamically for you and how they have reduced the plumbing you need to make applications.
Factory:
<!DOCTYPE html> <html> <head lang="en"> <meta charset="utf-8"> <title>Egghead Videos</title> <link rel="stylesheet" href="vendor/foundation/foundation.min.css"> </head> <body> <div ng-app="app" ng-controller="AppCtrl"> <h1 class="panel">{{title}}</h1> </div> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js"></script> <script type="text/javascript" src="app/js/main.js"></script> </body> </html>
var app = angular.module("app", []); app.factory("game", function() { return { title: "StarCraft" } }) app.controller("AppCtrl", function($scope, game) { $scope.title = game.title });
"app.factory" is just simply short-hand for using this "provide object":
/** * Created by Answer1215 on 12/27/2014. */ var app = angular.module("app", []); app.config(function($provide) { $provide.factory("game", function() { return{ title: "StarCraft" } }) }) app.controller("AppCtrl", function($scope, game) { $scope.title = game.title });
"Factory" is really just shorthand for the provider which sets up a more generic provider which returns things or objects that have "get" functions:
/** * Created by Answer1215 on 12/27/2014. */ var app = angular.module("app", []); app.config(function($provide) { $provide.provider("game", function() { return{ $get: function() { return{ title: "StarCraft" } } } }) }) app.controller("AppCtrl", function($scope, game) { $scope.title = game.title });
If you want to set up something like game provider and set the type of game:
/** * Created by Answer1215 on 12/27/2014. */ var app = angular.module("app", []); app.provider("game", function() { var type; return{ setType: function(title) { type = title; }, $get: function() { return{ title: type + "Craft" } } } }) app.config(function(gameProvider) { gameProvider.setType("War"); }) app.controller("AppCtrl", function($scope, game) { $scope.title = game.title });
