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.

<!DOCTYPE html>
<html lang="en" ng-app = "myModule">
        <head>
                <meta charset="UTF-8"  name="viewport" content="width=device-width, initial-scale=1"/>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
        </head>
<body ng-controller="myController">
        <nav class="navbar navbar-default">
                <div class="containet-fluid">
                        <a class="navbar-brand" href = "https://www.sourcecodester.com" >Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class = "text-primary">JavaScript - Simple Get Array Element Using AngularJS</h3>
                <hr style = "border-top:1px dotted #ccc;"/>
                <div class = "container-fluid">
                        <button ng-click="getArray();" class="btn btn-primary">Get Array</button>
                        <br /><br />
                        <table class = "table table-bordered">
                                <thead class="alert-info">
                                        <tr>
                                                <th>Student ID</th>
                                                <th>Firstname</th>
                                                <th>Lastname</th>
                                                <th>Grade</th>
                                        </tr>
                                </thead>
                                <tbody>
                                        <tr ng-repeat = "student in students">
                                                <td>{{$index+1}}</td>
                                                <td>{{student.firstname}}</td>
                                                <td>{{student.lastname}}</td>
                                                <td>{{student.grade}}</td>
                                        </tr>
                                </tbody>
                        </table>
                </div>
        </div>  
</body>
<script src ="js/jquery-3.2.1.min.js"></script> 
<script src = "js/angular.js"></script>
<script src = "js/script.js"></script>
<script src ="js/bootstrap.js"></script>        
</html>

Creating the Main Function

This code contains the main function of the application. This code will display an array 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.

var app = angular.module("myModule", [])
                                                           .controller("myController", function($scope){
                                                                
                                                                $scope.arrays = [
                                                                        {firstname: "John", lastname: "Smith", grade: "2"},
                                                                        {firstname: "Claire", lastname: "Temple", grade: "8"},
                                                                        {firstname: "Ash", lastname: "Ketchump", grade: "4"},
                                                                ];
                                                                        
                                                                $scope.getArray = function(){
                                                                        $scope.students = $scope.arrays;
                                                                }
