index.html:
This is the main HTML file that defines the structure of the webpage.
It includes a title, a container with a heading, an input field for adding tasks, a button to add tasks, and an unordered list (
<ul>) for displaying the tasks.The script file (
script.js) is included at the end of the body.
styles.css:
This file contains the styles (CSS) for the HTML elements to make the app visually appealing.
It defines the styling for the body, container, list items, and buttons.
The styling includes a simple layout, background colors, borders, padding, and margins.
script.js:
- This is the JavaScript file that provides the functionality for the to-do app.
JavaScript Explanation:
Get references to HTML elements:
taskInput: Represents the input field where the user can enter a new task.taskList: Represents the unordered list where the tasks will be displayed.
addTaskfunction:Retrieves the value from the input field (
taskInput).Checks if the input is not empty.
Creates a new list item (
<li>) and sets its HTML content to include the task text and a "Remove" button.Appends the new list item to the task list (
taskList).Clears the input field.
removeTaskfunction:Takes a reference to the button that was clicked.
Traverses the DOM to get the parent list item (
<li>).Removes the list item from the task list.
Overall Flow:
The user enters a task in the input field and clicks "Add Task."
The
addTaskfunction is called:It checks if the input is not empty.
Creates a new list item with the task text and a "Remove" button.
Appends the list item to the task list.
Clears the input field.
The user can see the added tasks in the unordered list.
Each task has a "Remove" button.
Clicking the "Remove" button calls the
removeTaskfunction, which removes the corresponding task from the list.
This creates a simple to-do app with basic functionality. You can build upon this foundation by adding features such as task completion, due dates, or storage using local storage or a backend server.
Conclusion:
In conclusion, creating a simple to-do app with JavaScript can be accomplished quickly and easily. This tutorial provides a basic foundation for building more complex and feature-rich applications. As you gain experience, consider enhancing the app by adding more functionality, improving the user interface, and exploring additional JavaScript libraries and frameworks.
