var myApp = angular.module('myApp', []); | |
//service style, probably the simplest one | |
myApp.service('helloWorldFromService', function() { | |
this.sayHello = function() { | |
return "Hello, World!" | |
}; | |
}); | |
//factory style, more involved but more sophisticated | |
myApp.factory('helloWorldFromFactory', function() { | |
return { | |
sayHello: function() { | |
return "Hello, World!" | |
} | |
}; | |
}); | |
//provider style, full blown, configurable version | |
myApp.provider('helloWorld', function() { | |
// In the provider function, you cannot inject any | |
// service or factory. This can only be done at the | |
// "$get" method. | |
this.name = 'Default'; | |
this.$get = function() { | |
var name = this.name; | |
return { | |
sayHello: function() { | |
return "Hello, " + name + "!" | |
} | |
} | |
}; | |
this.setName = function(name) { | |
this.name = name; | |
}; | |
}); | |
//hey, we can configure a provider! | |
myApp.config(function(helloWorldProvider){ | |
helloWorldProvider.setName('World'); | |
}); | |
function MyCtrl($scope, helloWorld, helloWorldFromFactory, helloWorldFromService) { | |
$scope.hellos = [ | |
helloWorld.sayHello(), | |
helloWorldFromFactory.sayHello(), | |
helloWorldFromService.sayHello()]; | |
} |
