client controller is not working

[hemantnh]

when i added $scope in the client controller for my existing code is not working the existing and $scope code, 

what is wrong in this ?

my exiting code :(used to pass the input values from cline to server side)

   c.passvalue = function(checkStatus) {

        c.data.value = checkStatus;

        //$window.alert('approvalState');

        c.server.update();

    }

after adding the $scope to the existing code one , the above code is not working 

api.controller = function($scope) {

   c.passvalue = function(checkStatus) {

        c.data.value = checkStatus;

        //$window.alert('approvalState');

        c.server.update();

    }

$scope.totalINC =$scope.data.incidents.length;

$scope.maxInc =10;

$scope.currentIndex=0;

$scope.pageNum= Math.cell($scope.totalINC/$scope.maxInc);

$scope.currentPage=0;

$scope.getNumber =function(){

return new Array($scope.pageNum);

}

}

Hi @hemantnh,

Let's set the context and understanding here.

As @Upender Kumar very nicely and clearly explains in the below article, there is a difference between $scope and data. The simple high level difference between them is:

$scope is the binding part between HTML (view) and JavaScript (controller)

data is the variable used on the server side which can be leveraged to retrieve values which you can pass to client-side/HTML.

$scope:

The Scope in Angular JS is the binding part between HTML (view) and JavaScript (controller) and it is a built-in object. It contains application data and objects. It is available for both the view and the controller. It is an object with available properties and methods. There are two types of scopes in Angular JS.

Example usage:

Client Side:

$scope.carname = "Volvo";

HTML

<h1>{{carname}}</h1>

data:

is the variable used on the server side which can be leveraged to retrieve values which you can pass to client-side/HTML.

Example usage:

Server Side:

data.msgClass='alert-success';

HTML:

<div class="{{data.msgClass}}"></div>

What are you trying to achieve?
