The Problem
Handling a form submission with plain JavaScript still means writing a backend to receive, validate, and route the data.
The Solution
Intercept the form's submit event, POST the data to your Formboost endpoint with fetch(), and let Formboost handle validation, storage, and delivery.
Setup in 5 Steps
Create a Formboost form endpoint
Give your HTML form an id and prevent default submit
Use fetch() to POST FormData to the endpoint
Show a success message or redirect on response.ok
Code Example
const form = document.querySelector('#contact-form');
form.addEventListener('submit', async (e) => {
e.preventDefault();
const formData = new FormData(form);
const response = await fetch('https://formboost.app/f/YOUR_ENDPOINT_ID', {
method: 'POST',
body: formData,
headers: { Accept: 'application/json' }
});
if (response.ok) {
form.reset();
document.querySelector('#success-message').hidden = false;
}
});Features That Work Great
