取Sevice和directive的引用
3: Grab any Services
We can grab a reference to any service using the injector function of element where ngApp was defined (or grab the $rootElement manually if using angular‘s bootstrap method):
> angular.element(‘html‘).injector().get(‘MyService‘)
-> Object {undo: function, redo: function, _pushAction: function, newDocument: function, init: function…}
We can then call methods on that service just like we could if we injected it.
4: Access controller for directive
Some directives define a controller with certain additional (often shared) functionality. To access the instance of a controller for a given directive from the console, just use the controller() function:
> angular.element(‘my-pages‘).controller()
-> Constructor {}
This last one is more advanced and not used as frequently.
