(13) AngularJs ng-repeat example (using module and controller)

 

We recommend you to review a simple example of ng-repeat directive before reading this post.

In the following example:

  • Using AngularJs controller and module, we create an array of students.
  • Each student has (first name, last name, gender, specialization, and level) information.
  • Then, we display the students information in an html page.
  • To display each student information, we use “ng-repeat” directive.

(12) AngularJs Two Way Data Binding Example (Student Information Form)

  • Using the AngularJs two way data binding, when you type the student information in the input field (Enter student information part), the value will immediately be displayed on the view part (View student information part).
  • Now, we don’t need any custom code to move data from the model to the view or from the view to the model.
  • ng-model directive can be used with the (input, select, and textarea) html tags.

(9) AngularJs Controller with Complex Object

The example demonstrates a controller object with more than one property: (firstname, lastname, specialization, and gender)

Note:

  • If you misspell a property name in the binding expression, angular expression will return null or undefined.
  • If you misspelled the controller name, an error will be raised, and the binding expressions will not be evaluated.

(8) AngularJs Modules and Controllers

  • An AngularJS module defines an application.
  • The  module is a container for the different parts of an application (controllers, services, directives, … ).
  • The controller is a JavaScript object. It controls the data of the AngularJs application.
  • Controllers always belong to a module.
  • The scope ($scope) is the binding part between the HTML (view) and the JavaScript (controller).


  • Create a JavaScript file. In the js file you should create the module, create the controller, and register controller with the module, as the following: 

1. To create the module:

                                       var app = angular.module(“myApp”, []);

     2. To create the controller: 

var myController = function ($scope){
$scope.msg = “Learning AngularJs”;
 }

3. To register the controller with the module:

myApp.controller(“myController”, myController);

(7) AngularJs ng-repeat directive

  • The ng-repeat directive repeats an HTML element.
  • In the following example:
  • Using ng-init, define a set of colors (red, blue, orange, and yellow).
  • Then, you should display each color in a list as bullet points.
  • Using ng-repeat, define the color (such as red) as an element in the colors group (You can use ul for the list).
  • Display each color in a single li as a bullet point.
