AngularJS in SharePoint 2013: Part 1

Introduction

AngularJS is perfect for Single Page Applications (SPAs) that extend HTML with new attributes. AngularJS is a JavaScript framework and it can be added to an HTML page with a <script> tag. AngularJS extends HTML attributes with Directives and binds data to HTML with Expressions. To learn more about AngularJS please refer to https://angularjs.org/.

AngularJS Directives

The ng-app directive tells AngularJS that the <div> element is the "owner" of an AngularJS application.

The ng-model directive binds the value of the input field to the application variable name.

The ng-controller directive defines the application controller.

The $scope of the controller is the application (the HTML element) it is referred from.

AngularJS expressions are written inside double braces as in {{expression }} and they can contain literals, operators and variables.

Example

  1. <!DOCTYPE html>  
  2. <html>  
  3. <body>  
  4.     <div ng-app="" ng-controller="controller">  
  5.         <!--ng-model binds the input field to the controller property firstName-->  
  6.         First Name: <input type="text" ng-model="user.firstName"><br>  
  7.         <!--ng-model binds the input field to the controller property lastName-->  
  8.         Last Name: <input type="text" ng-model="user.lastName"><br>  
  9.         <br>  
  10.         <!--{{}} AngularJS expression-->  
  11.         Welcome {{fullName()}}  
  12.     </div>  
  13.   
  14.     <script>  
  15.         function controller($scope) {  
  16.             // $scope.user is the property for controller object  
  17.             // firstName & lastName are the properties for user object  
  18.             $scope.user = { firstName: "", lastName: "", };  
  19.             $scope.fullName = function () {  
  20.                 var x = $scope.user;  
  21.                 return x.firstName + " " + x.lastName;  
  22.             }  
  23.         }  
  24.     </script>  
  25.     <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>  
  26. </body>  
  27. </html>
