Webflow's native form validation is helpful, but sometimes you need finer control and custom error handling. Here's how to achieve that with short and clean code:
1. Basic Validation with JavaScript:
Example:
JavaScript
function validateForm() {
const nameInput = document.getElementById('name');
const emailInput = document.getElementById('email');
const messageInput = document.getElementById('message');
let isValid = true;
if (!nameInput.value) {
showError(nameInput, 'Name is required.');
isValid = false;
} else {
hideError(nameInput);
}
if (!emailInput.value || !/\S+@\S+\.\S+/.test(emailInput.value)) {
showError(emailInput, 'Please enter a valid email address.');
isValid = false;
} else {
hideError(emailInput);
}
if (!messageInput.value || messageInput.value.length < 10) {
showError(messageInput, 'Message must be at least 10 characters long.');
isValid = false;
} else {
hideError(messageInput);
}
return isValid;
}
function showError(element, message) {
const errorElement = document.getElementById(element.id + '-error');
errorElement.textContent = message;
errorElement.classList.add('active');
}
function hideError(element) {
const errorElement = document.getElementById(element.id + '-error');
errorElement.textContent = '';
errorElement.classList.remove('active');
}
document.getElementById('contact-form').addEventListener('submit', function(event) {
event.preventDefault();
if (!validateForm()) return;
// Submit form using Webflow API or other method
});
