In this tutorial we will create a Create, Read, Delete, Update Functions Using AngularJS. This code can create, read, delete, update data the when user click one the buttons. The code use AngularJS directives to call a function that divided into a different functionalities that manipulate the data entry within the array object. This a user-friendly program feel free to modify and use it to your system. We will be using AngularJS as a framework which has additional custom HTML attributes embedded into it. It can interprets those attributes as directives to bind inputted parts of the page to a model that represent as a standard JavaScript variables.

Getting Started:

First you have to download Bootstrap, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/. And, this is the link for the AngularJS https://angularjs.org/.

This is where we will create a simple form for our application. To create the forms simply copy and write it into you text editor, then save it index.html. 
  1. <!DOCTYPE html>
  2. <html lang="en" ng-app="myModule">
  3. 	<head>

  11. 		</div>
  12. 	</nav>
  13. 	<div class="col-md-3"></div>
  14. 	<div class="col-md-6 well">

Creating the Main Function

This code contains the main function of the application. This code will create, read, delete, update a data when the button is clicked To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js directory. 
  1. var app = angular.module("myModule", [])
  2. 							   .controller("myController", function($scope){
  3.  
  4. 								$scope.newMember = {};
  5. 								$scope.clickedMembers = [];
  6.  
  7.  
  8. 								$scope.members = [];
  9.  
  10. 								$scope.saveMember = function(){
  11. 									$scope.members.push($scope.newMember);
  12. 									$scope.newMember = {};
  13. 								};		
  14.  
  15. 								$scope.selectMember =  function(member){
  16. 									$scope.selectedMember = member;
  17. 								};
  18.  
  19. 								$scope.deleteMember = function(){
  20. 									$scope.members.splice($scope.members.indexOf($scope.selectedMember), 1);
  21. 								};
