Call Controller

Call Controller

Run this demo in my JavaScript Demos project on GitHub. The Scope instance was the view model, before this shift towards controller as approach. And it made it incredibly plain simple to consume the 'view model' from within link function, since the cope has been the 1-st argument injected to every directive link function. So here's the question. Now that the Scope is isolated for events and 'digest access', where has been 'view model'?

We usually can explicitly require, when defining the directive configuration object. In the succeeding demo, I'm using the link function as the glue betwixt 'userinitiated' clickevents and viewmodel methods. Component controller has been exposing, as you usually can see., clickCount as an important element of 'view model'. As a consequence, directive link function usually can then consume this method first-hand on injected controller instance.

With that said, it makes a bunch of impression, once you see how this works. When you are probably coming from a background in which Scope object is view model, it will be a bit confusing when switching to the controller use as the view model. For instance, hopefully this post helps clarify how that transition will be pulled through to all aspects of our component directies in AngularJS. Nonetheless, controllers will be passed as an array. Of course the directive string has to be exact string that defines the directive.

What about using bindToController property in the directive configuration object? Setting the bindToController property to very true enables the isolate scope properties to be bound to the controller, not the scope Object. Avoiding the responsibility to inject the scope object to controller.

Here you will see bindToController property at work https. JavaScriptDemos'/blob/master/demos/accessing vm in link angularjs/index. Now pay attention please. Why did you chose to use 'element. Otherwise, they wouldn't have needed link function at all for this demo. Just keep reading! That said, we will usually use ngclick and after all solely defer to the link function for extraordinary interaction use cases.

I'm on the fence about the bindToController property, in order to be honest. While, and, right after having played around with ReactJS a bit, we practically choose NOT to use the property anyway. The cause of this is that it creates a meaningful separation betwixt the incoming scope values and internal viewmodel values. I'm sure you heard about this. BEFORE invoking. Div' element from it's current spot in DOM throw it somewhere else.

Needless to say, inside link function I was able to assign scope. Now please pay attention. Now my functions back in directive controller may reference vm. Now let me tell you something. Thanks for this tip. Now pay attention please. This was the best way they could access directive's own controller, as I was importing controller from parent directive.

In that post, I'm using require to involve all current component controller and in addition ngModelController. There is a lot more info about this stuff here. ModelController to component controller. Would be interesting to you. Glad assisting. Accessing the controller as a Array solely happens in case you *require* more than one controller. You can find a lot more info about this stuff here.it comes through as a single reference, when you require a single controller. They come thru as an array in the same order that they were required, when you require multiple controllers.
