I'm still a debutant on Angularjs. I want to inject dynamically a dependency of a service (that I created) in my controller.
But when I code a service with dependencies, I got this error :
Error: Unknown provider: $windowProvider <- $window <- base64
This is the code of the controller.
var base64 = angular.injector(['servicesModule']).get('base64');
console.log("base64", base64.encode("my text will be encoded"));
This code works:
var servicesModule = angular.module('servicesModule', []);
servicesModule.factory('base64', function() {
return {
name: 'base64',
readonly: false,
encode: function(input) {
return window.btoa(input);
},
decode: function(input) {
return window.atob(input);
}
};
});
This code doesn't work :
var extModule = angular.module('ext', []);
extModule.factory('base64', ['$window', function($window) {
return {
name: 'base64',
readonly: false,
encode: function(input) {
return $window.btoa(input);
},
decode: function(input) {
return $window.atob(input);
}
};
}]);
Another problem is when the service is in the same module as the controller. If the module has dependencies, I doesn't work (I have $routeProvider dependence in my module config) :
Error: Unknown provider: $routeProvider from mainModule
var mainModule = angular.module('main', [],
function($routeProvider, $locationProvider) {
//Some routing code
}
);
JS Fiddles
Same module with dependencies(controller + service) : http://jsfiddle.net/yrezgui/YedT2/
Different module with dependencies : http://jsfiddle.net/yrezgui/YedT2/4/
Different module without dependencies : http://jsfiddle.net/yrezgui/YedT2/5/
Don't call angular.injector() -- this creates a new injector. Instead, inject the already-created $injector into your controller and use it:
So instead of:
var algoController = function($scope) {
$scope.base64 = angular.injector(['main']).get('base64');
};
Do this:
var algoController = function($scope, $injector) {
$scope.base64 = $injector.get('base64');
};
But most of the time you should inject your service directly, rather than dynamically, like so:
var algoController = function($scope, base64) {
$scope.base64 = base64;
};
