Model Databinding in AngularJS

Here you learn what is model in angular js, how to define model within script, how angular data binding works with html elements etc.

Let’s understand angular data model, how to display angular data in html page.

First we need to understand what is data model in Angular.js, then how to bind that data with html element.

The data model is the collection of data available for the application, let's look at the example below.

<script>
var _module = angular.module('wtrModule', []);
_module.controller('wtrCtrl', function ($scope) {
$scope.studentName = "Arijit Bramhachari";
$scope.studentAddress = "S. V. Road, Malad West, Mumbai";
});
</script>

Now if you look at the above code, following things are done.

• First creating a module

  var _module = angular.module('wtrModule', []);
              

• In module we are creating controller with multiple properties and setting the values of each property at the same time.

  _module.controller('wtrCtrl', function ($scope) {
      $scope.studentName = "Arijit Bramhachari";
      $scope.studentAddress = "S. V. Road, Malad West, Mumbai";
  });

In AngularJS we can bind data in two different ways, ng-bind is the attribute used for databinding

Approach 1: using ng-bind attribute

<div ng-app="wtrModule" ng-controller="wtrCtrl">
<p ng-bind="studentName"> </p>
</div>

Approach 2: using {{ propertyName }}

<div ng-app="wtrModule" ng-controller="wtrCtrl">
<p>{{studentName}} at {{studentAddress}} </p>
</div>

Now here you can see the result of angular data binding using above two techniques

Hope you understood model data binding in angularjs.
