在
referenceI读：
Lastly,it is important to realize that all Angular services are
application singletons. This means that there is only one instance of
a given service per injector.
但是用这个简单的代码似乎不是一个单例
'use strict';
angular.module('animal',[])
.factory('Animal',function(){
return function(vocalization){
return {
vocalization:vocalization,vocalize : function () {
console.log('vocalize: ' + this.vocalization);
}
}
}
});
angular.module('app',['animal'])
.factory('Dog',function (Animal) {
return Animal('bark bark!');
})
.factory('Cat',function (Animal) {
return Animal('meeeooooow');
})
.controller('MainCtrl',function($scope,Cat,Dog){
$scope.cat = Cat;
$scope.dog = Dog;
console.log($scope.cat);
console.log($scope.dog);
//$scope.cat = Cat;
});
我有点困惑你能解释我什么事？

可能我不是在棚子里最锋利的工具
但是在@Khanh TO回复它会是一个更好
解释在参考它不是很清楚。

'use strict';
angular.module('animal',function(){
return {
vocalization:'',vocalize : function () {
console.log('vocalize: ' + this.vocalization);
}
}
});
angular.module('dog',function (Animal) {
Animal.vocalization = 'bark bark!';
Animal.color = 'red';
return Animal;
});
angular.module('cat',['animal'])
.factory('Cat',function (Animal) {
Animal.vocalization = 'meowwww';
Animal.color = 'white';
return Animal;
});
angular.module('app',['dog','cat'])
.controller('MainCtrl',Dog){
$scope.cat = Cat;
$scope.dog = Dog;
console.log($scope.cat);
console.log($scope.dog);
//$scope.cat = Cat;
});
BOOM这是一个单身！

但如果你喜欢
'use strict';
angular.module('animal',function (Animal) {
function ngDog(){
this.prop = 'my prop 1';
this.myMethod = function(){
console.log('test 1');
}
}
return angular.extend(Animal('bark bark!'),new ngDog());
})
.factory('Cat',function (Animal) {
function ngCat(){
this.prop = 'my prop 2';
this.myMethod = function(){
console.log('test 2');
}
}
return angular.extend(Animal('meooow'),new ngCat());
})
.controller('MainCtrl',Dog){
$scope.cat = Cat;
$scope.dog = Dog;
console.log($scope.cat);
console.log($scope.dog);
//$scope.cat = Cat;
});
有用
