angularjsHow do I create an example using AngularJS?
The following example uses AngularJS to create a simple application that will display a greeting message when a button is clicked.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.name = "";
$scope.greeting = function() {
alert("Hello " + $scope.name);
}
});
</script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
Name: <input type="text" ng-model="name">
<button ng-click="greeting()">Greet</button>
</div>
</body>
</html>
This example creates an AngularJS application with a controller named myCtrl
that has a single scope variable name
. The controller also has a function named greeting
that will display an alert box with a greeting message when called. The HTML body contains a single div element that is associated with the myApp
module and myCtrl
controller. Inside the div element, there is an input field and a button. The input field is bound to the scope variable name
using the ng-model
directive. The button is associated with the greeting
function using the ng-click
directive.
