JavaScript Expense Tracker App: Manage Your Finances Efficiently
Expense Tracker App in JavaScript
An expense tracker app is a useful tool for managing your finances. It can help you to track your spending habits, identify areas where you can cut back, and set financial goals. There are many different expense tracker apps available, but you can also create your own using JavaScript.
To develop an expense tracker app in JavaScript, you will need to:
- Create an HTML structure for the app. This will include the basic layout of the app, such as the header, footer, and main content area.
- Add CSS styling to the app. This will control the appearance of the app, such as the font, colors, and spacing.
- Add JavaScript code to the app. This will add interactivity to the app, such as the ability to add, edit, and delete expenses.
1. HTML structure for expense tracker:
<!DOCTYPE html>
<html>
<head>
<title>Expense Tracker App</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Expense Tracker App</h1>
<form action="/add_expense" method="post">
<input type="text" name="expense_name" placeholder="Expense name">
<input type="number" name="expense_amount" placeholder="Expense amount">
<select name="expense_category">
<option value="food">Food</option>
<option value="transportation">Transportation</option>
<option value="entertainment">Entertainment</option>
<option value="other">Other</option>
</select>
<button type="submit">Add Expense</button>
</form>
<table>
<thead>
<tr>
<th>Expense Name</th>
<th>Expense Amount</th>
<th>Expense Category</th>
<th>Date</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
</body>
</html>2.Add CSS styling to the app.
body {
font-family: sans-serif;
}
h1 {
text-align: center;
}
form {
margin: 0 auto;
width: 500px;
}
input {
width: 100%;
padding: 10px;
margin-bottom: 10px;
}
select {
width: 100%;
padding: 10px;
margin-bottom: 10px;
}
button {
width: 100%;
padding: 10px;
margin-bottom: 10px;
background-color: #000;
color: #fff;
}
table {
width: 100%;
border-collapse: collapse;
}
th, td {
border: 1px solid #ccc;
padding: 10px;
}3. Add JavaScript code to the app.
// Get the expense form
const expenseForm = document.querySelector('#expenseForm');
// Add an event listener to the form submit event
expenseForm.addEventListener('submit', function(event) {
// Prevent the default form submission behavior
event.preventDefault();
// Get the expense data from the form
const expenseName = expenseForm.querySelector('[name="expense_name"]').value;
const expenseAmount = expenseForm.querySelector('[name="expense_amount"]').value;
const expenseCategory = expenseForm.querySelector('[name="expense_category"]').value;
// Add the expense data to the table
const tableBody = document.querySelector('tbody');
const tableRow = document.createElement('tr');
tableRow.innerHTML = `
<td>${expenseName}</td>
<td>${expenseAmount}</td>
<td>${expenseCategory}</td>
<td>${new Date().toLocaleDateString()}</td>
`;
tableBody.appendChild(tableRow);
// Clear the expense form
expenseForm.reset();
});This is just a basic example, of Expense Tracker App in JavaScript. You can add more features to your expense tracker app, such as the ability to filter expenses by date, category, or amount. You can also add charts and graphs to visualize your spending data.
Once you have developed your expense tracker app, you can publish it online so that others can use it. You can also use it yourself to track your own expenses and improve your financial management.
