HTML, CSS, and JavaScript contact form validation example
Here’s a simple example of how you can validate a contact form using HTML, CSS, and JavaScript:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Contact Form</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<form id="contactForm" onsubmit="submitForm(event)">
<h2>Contact Us</h2>
<div class="input-group">
<label for="name">Name:</label>
<input type="text" id="name" class="form-input" required>
</div>
<div class="input-group">
<label for="email">Email:</label>
<input type="email" id="email" class="form-input" required>
</div>
<div class="input-group">
<label for="message">Message:</label>
<textarea id="message" class="form-input" rows="4" required></textarea>
</div>
<button type="submit" class="submit-button">Submit</button>
</form>
</div>
<script>
function submitForm(event) {
event.preventDefault();
// Validate form data
var name = document.getElementById('name').value;
var email = document.getElementById('email').value;
var message = document.getElementById('message').value;
if (name === "" || email === "" || message === "") {
alert("Please fill in all fields");
return;
}
// Send mail using your preferred server-side language (PHP in this case)
// Replace 'your_mail_script.php' with the actual script that sends the email
var xhr = new XMLHttpRequest();
xhr.open("POST", "your_mail_script.php", true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
alert("Thank you for contacting us! We will get back to you soon.");
document.getElementById('contactForm').reset();
}
};
var data = "name=" + encodeURIComponent(name) +
"&email=" + encodeURIComponent(email) +
"&message=" + encodeURIComponent(message);
xhr.send(data);
}
</script>
</body>
</html>
/* styles.css */
body {
font-family: 'Arial', sans-serif;
background-color: #f4f4f4;
margin: 0;
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
.container {
background-color: #fff;
padding: 30px;
border-radius: 8px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}
form {
display: grid;
gap: 20px;
}
.input-group {
display: grid;
gap: 5px;
}
label {
font-weight: bold;
}
.form-input {
width: 100%;
padding: 8px;
border: 1px solid #ccc;
border-radius: 4px;
}
.submit-button {
background-color: #4caf50;
color: #fff;
padding: 10px;
border: none;
border-radius: 4px;
cursor: pointer;
}
.submit-button:hover {
background-color: #45a049;
}
Note: Replace "your_mail_script.php" with the actual server-side script that processes the form and sends the email. Additionally, ensure that your server supports the chosen server-side language (PHP in this example).
