Creating a to-do list is a great project for beginners looking to enhance their skills in JavaScript and HTML. This interactive application will allow users to add tasks, mark them as complete, and delete them as needed. In this blog post, we will walk through the steps to build a simple to-do list using JavaScript for functionality and HTML for structure.
What You Will Learn 📚
How to set up the HTML structure for the to-do list.
Using JavaScript to add, delete, and mark tasks as complete.
Basic styling tips to enhance the user interface.
Step 1: Setting Up the HTML Structure 🏗️
First, we need to create the basic structure of our to-do list using HTML. Here’s how you can set it up:
xml
<!DOCTYPE html>
Simple To-Do List
<!-- Link to your CSS file -->
My To-Do List
Add Task
<!-- Link to your JavaScript file -->
Explanation:
- Input Field: Where users can type their tasks.
- Button: When clicked, it adds the task to the list.
- Unordered List: Displays the added tasks.
Step 2: Adding JavaScript Functionality ⚙️
Now that we have our HTML set up, let’s add some functionality using JavaScript.
Create a file named script.js and add the following code:
javascript
document.getElementById('addTaskBtn').addEventListener('click', addTask);
function addTask() {
const taskInput = document.getElementById('taskInput');
const taskValue = taskInput.value;
if (taskValue === '') {
alert("You must write something!");
return;
}
const li = document.createElement('li');
li.textContent = taskValue;
// Create a delete button
const deleteBtn = document.createElement('span');
deleteBtn.textContent = ' ❌';
deleteBtn.className = 'deleteBtn';
deleteBtn.onclick = function() {
li.remove();
};
li.appendChild(deleteBtn);
// Mark task as complete
li.onclick = function() {
li.classList.toggle('checked');
};
document.getElementById('taskList').appendChild(li);
// Clear input field
taskInput.value = '';
}
Explanation:
- Event Listener: Listens for clicks on the "Add Task" button.
- Adding Tasks: When clicked, it creates a new list item with the task text and a delete button.
- Delete Functionality: The delete button removes the task from the list when clicked.
- Marking as Complete: Clicking on a task toggles its completion status.
Step 3: Basic Styling with CSS 🎨
To make our to-do list visually appealing, let’s add some basic styles. Create a file named styles.css and include the following CSS:
css
body {
font-family: Arial, sans-serif;
}
app {
max-width: 400px;
margin: 0 auto;
}
h1 {
text-align: center;
}
input[type="text"] {
width: 70%;
padding: 10px;
}
button {
padding: 10px;
}
ul {
list-style-type: none;
padding-left: 0;
}
li {
display: flex;
justify-content: space-between;
padding: 10px;
border-bottom: 1px solid #ccc;
}
.checked {
text-decoration: line-through;
}
.deleteBtn {
cursor: pointer;
}
Explanation:
- Styling Elements: Basic styles are applied to make the input field, button, and list items look good.
- Checked Class: Adds a line-through effect for completed tasks.
