AngularJS
Scope & Controller
Gias Kay Lee
Scope in AngularJS
is a plain old Javascript object
$scope
{
$$childHead: Child
$$childTail: Child
$$listeners: Object
$$nextSibling: Child
$$prevSibling: null
$$watchers: Array[2]
$id: '004'
$parent: Child
...
}
Each
Controller Instance
has its own Scope
The properties of a Scope is the
corresponding Controller's
Model
And the
View Template
knows nothing about the Controller
...except those
exposed through the Scope
Kinda Like a ViewModel
Let's see some examples!
