By:

In this article, I will show you two way data binding angularjs tutorial with examples. The model and view will be synchronized at all time. It means a change in the model will automatically keep on changing view updates the model automatically. 

 

script.js 

///<reference path="Script/angular.min.js" />
var myapp = angular.module("Module1", [])
            .controller("mycontroller",function($scope) {
                $scope.message= "Hello World";
            });

 

View:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.js"></script>
<script src="Script.js" type="text/javascript"></script>
<body ng-app="Module1">
    <div ng-controller="mycontroller">     
        <div>
            <input type="text" ng-model="message" /> </br></br>
            {{ message }}
        </div>
    </div>
</body> 

 

Description: 

As here, I added a simple message property to the scope object and use this message property within binding expression [{{ message }}] in our view to display hello world. By the help of the binding expression, it updates the view when the model changes and the Data binding are achieved by the ng-model directive. The ng-model helps to update the model when the view changes.


Output:
