What is the relationship between angularjs Scope with controller view

Question

Want to know about what happens if ng-controller is defined without any reference of controller and vice-versa.

Answer 1

Let us consider the below block:

<div ng-controller="emp">  //emp is the controller name

.........(View Part)

</div>

When above block is compiled, it tries to create boundary/context which is stored in some browser memory that contains some data in block which is not shown to user.

The boundary/context is then attached to ng-controller="emp" block. So the boundary has the direct accessed by the block.

This boundary/context is called as scope. So when you mention emp you are saying to create new controller instance along with scope being merged. Now,Scope acts as a mediator between controller instance and view(block).

Now,finally if view wants to send data to controller then it send through scope and vice-versa.

Explanation of above is attached for your reference:
