AngularJS Model Tutorial
View more Tutorials:
ngModel is a built-in Directive of AngularJS. It defines a new property such as ng-model, which can apply to the HTML Controls (input, textarea, select). This Directive helps two-way binding between the values of HTML Control and application data.

OK, a simple example. In this example, I will perform the two-way binding between the value of a <input> and $scope.fullName. This means if the value of <input> changes, it will be updated into the $scope.fullName, and vice versa if the $ scope.fullName value changes it will be updated to <input>.

model-example.js
// Create an Application named "myApp". var app = angular.module("myApp", []); // Create a Controller named "myCtrl" app.controller("myCtrl", function($scope) { $scope.fullName = "Anonymous"; });
