ngController
(directive in module ng
)
The ngController directive assigns behavior to a scope. This is a key aspect of how angular
supports the principles behind the Model-View-Controller design pattern.
MVC components in angular:
ngController directive specifies a Controller class; the class has
methods that typically express the business logic behind the application.Note that an alternative way to define controllers is via the <a href="api/ng.$route"><code>ng.$route</code></a>
service.
<ANY ng-controller="{expression}">
...
</ANY>
as class<ANY class="ng-controller: {expression};">
...
</ANY>
ngController – {expression} –
Name of a globally accessible constructor function or an expression that on the current scope evaluates to a constructor function.
Here is a simple form for editing user contact information. Adding, removing, clearing, and
greeting are methods declared on the controller (see source tab). These methods can
easily be called from the angular markup. Notice that the scope becomes the this for the
controller's instance. This allows for easy access to the view data from the controller. Also
notice that any changes to the data are automatically reflected in the View without the need
for a manual update.
