How to create a TODO list project in AngularJs?

Ravi Vishwakarma 51 09-May-2024

Let's create a new project in AngularJS named ToDo List.
This project has 2 parts,

  1. HTML
  2. JavaScript

We design the UI part of our project in the HTML part, and in the second Javascript part, we write AngularJS code for internal work.

I am adding Bootstrap CDN to my project for better UI design because CDN is fast, updated versions, and doesn't need to save files in your drive.

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap demo</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">
  </head>
  <body>
    <h1>Hello, world!</h1>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-YvpcrYf0tY3lHB60NNkmXc5s9fDVZLESaAA55NDzOxhy9GkcIdslK1eN7N6jIeHz" crossorigin="anonymous"></script>
  </body>
</html>

Now, I add AngularJS CDN same as Bootstrap CDN for working with AngularJS.

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap demo</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">
  </head>
  <body>
    <h1>Hello, world!</h1>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-YvpcrYf0tY3lHB60NNkmXc5s9fDVZLESaAA55NDzOxhy9GkcIdslK1eN7N6jIeHz" crossorigin="anonymous"></script>
    <!-- Angurr JS CDN  -->
    <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.8.3/angular.min.js" 
                integrity="sha512-KZmyTq3PLx9EZl0RHShHQuXtrvdJ+m35tuOiwlcZfs/rE7NZv29ygNA8SFCkMXTnYZQK2OX0Gm2qKGfvWEtRXA==" 
                crossorigin="anonymous" referrerpolicy="no-referrer">
   
  </body>
</html>

Now, Create the two files in the located folder, first "index.html" for HTML code and the second "app.js" for AngularJS code.

index.html

<!doctype html>
<html lang="en" data-ng-app="todoApp">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.11.3/font/bootstrap-icons.min.css">
  </head>
  <body>

    <div class="container" data-ng-controller="TodoController as todoCtrl">
        <h1 class="text-center">Todo List</h1>
        <form data-ng-submit="todoCtrl.addTask()" class="row g-3">

                <input type="text" data-ng-model="todoCtrl.newTask" placeholder="Add a new task" class="form-control" />
            </div>
            <div class="col-12">

                </button>
            </div>
        </form>
        <div class="table-responsive my-3">
            <table class="table">

                    <tr data-ng-repeat="task in todoCtrl.tasks">

“app.js”

var todoApp = angular.module('todoApp', [])
    .controller('TodoController', function () {
        var todoCtrl = this;
        todoCtrl.tasks = [];
        todoCtrl.newTask = '';

        todoCtrl.addTask = function () {
            if (todoCtrl.newTask !== '') {
                todoCtrl.tasks.push({'name' : todoCtrl.newTask, 'time' : new Date().toString(), 'iscomplete' : false});
                todoCtrl.newTask = '';
            }
        };

        todoCtrl.completeTask = function (index) {
            if(index>-1 && index < todoCtrl.tasks.length)
            {
                var completedTask = todoCtrl.tasks[index];
                completedTask.iscomplete = true;
                window.alert("Your \"" + completedTask.name + "\" task is completed.");
            }
        };

        todoCtrl.removeTask = function (index) {
            if(index>-1 && index < todoCtrl.tasks.length)
            {
                todoCtrl.tasks.splice(index, 1);
            }
        };
    });

In this code, I created "todoApp" module for my project, and also added "TodoController" controller for the internal process of my todo list project. I was define three functions in my controller,

  1. addTask: It is used to add new tasks to my tasks list.
  2. completeTask: It is used to check whether the task is complete or not, then show a pop-up.
  3. removeTask: It is used to remove tasks from the task list using an index.

 

Thank You.
