It is not at al giving the result. Help me to find where I was wrong

View:

ViewBag.Title = "Home Page";

}

GrossWanges:

OverTime :

ChildSupport :

Total : {{a--b--c}}

AngularJs:

var FinancialsApp = angular.module("MyFinancialsApp", [])

.controller("MyController",function($scope)){

$scope.UpdateVal=function(){

$scope.TotalVaue=($scope.a)+($scope.b)+($scope.c);

}

});

Hi Monica,

Change the below code and try again,

@{
ViewBag.Title = "Home Page";
}
GrossWanges:
OverTime :
ChildSupport :

var FinancialsApp = angular.module("MyFinancialsApp", [])
.controller("MyController",function($scope)){
$scope.UpdateVal=function(){
var total=($scope.a)+($scope.b);
return total;
}
});

<body ng-controller="MainCtrl">

<p> Add the Numbersp>   <p>

<input type="text" ng-model="val1" ng-change="updateSum()">

+     <input type="text" ng-model="val2" ng-change="updateSum()">

=     <input type="text" disabled ng-model="sumVal">   p> body>
js
var app = angular.module('plunker', []);



app.controller('MainCtrl', function($scope) {

  $scope.name = 'World';

  $scope.updateSum = function() {

    $scope.sumVal = ($scope.val1 * 1) + ($scope.val2 * 1);

  }

});

Hi,

Please try below script -

var FinancialsApp = angular.module("MyFinancialsApp", []).controller("MyController", function ($scope) {

$scope.UpdateVal = function () {

$scope.TotalVaue = ($scope.a) + ($scope.b) + ($scope.c);

}

});

There was a extra parentheses in your script.

Hi Monica,

I think the error in line is ,

$scope.TotalVaue=($scope.a)+($scope.b)+($scope.c); You have't declare angular model for Total value in your html code. Please check.

make changes in below line,

ng-model="TotalValue">Total : {{a--b--c}}
