首先,創建一個基本的 HTML 結構:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>To-Do List</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<h1>To-Do List</h1>
<input type="text" id="taskInput" placeholder="Add a new task">
<button id="addTaskButton">Add Task</button>
<ul id="taskList"></ul>
</div>
<script src="script.js"></script>
</body>
</html>
接著,添加一些基本的樣式:
/* styles.css */
body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
margin: 0;
padding: 0;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}
.container {
background-color: #fff;
padding: 20px;
border-radius: 5px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
width: 300px;
}
input[type="text"] {
width: calc(100% - 22px);
padding: 10px;
margin-bottom: 10px;
border: 1px solid #ddd;
border-radius: 3px;
}
button {
padding: 10px;
background-color: #28a745;
border: none;
color: #fff;
border-radius: 3px;
cursor: pointer;
}
button:hover {
background-color: #218838;
}
ul {
list-style-type: none;
padding: 0;
}
li {
padding: 10px;
border-bottom: 1px solid #ddd;
}
li:last-child {
border-bottom: none;
}
.deleteButton {
margin-left: 10px;
background-color: #dc3545;
border: none;
color: #fff;
border-radius: 3px;
cursor: pointer;
}
.deleteButton:hover {
background-color: #c82333;
}
最後,實現基本的功能:
// script.js
document.addEventListener('DOMContentLoaded', () => {
const taskInput = document.getElementById('taskInput');
const addTaskButton = document.getElementById('addTaskButton');
const taskList = document.getElementById('taskList');
addTaskButton.addEventListener('click', () => {
const taskText = taskInput.value.trim();
if (taskText !== '') {
const li = document.createElement('li');
li.textContent = taskText;
// Add a delete button to each task
const deleteButton = document.createElement('button');
deleteButton.textContent = 'Delete';
deleteButton.className = 'deleteButton';
deleteButton.addEventListener('click', () => {
taskList.removeChild(li);
});
li.appendChild(deleteButton);
taskList.appendChild(li);
taskInput.value = '';
}
});
// Allow pressing Enter to add tasks
taskInput.addEventListener('keypress', (e) => {
if (e.key === 'Enter') {
addTaskButton.click();
}
});
});
這樣,你就有了一個基本的 To-Do List 應用程序。可以進一步擴展功能,比如儲存任務到本地,進行儲存、編輯任務等。
