No jQuery dependency
Vanilla JS using fetch + FormData. Works in every modern browser.
Feature
AJAX submissions
No page reloads, no bloat. A single small JS file handles validation, submission, and success states.
Part of Core Forms — every premium WordPress form feature in one plugin, one license, unlimited sites.
Submissions go through a single AJAX action that runs the same validation, captcha, action-loop and payment-redirect pipeline whether the form is on a WordPress page, in the Gutenberg block, or behind the headless REST endpoint.
The frontend script is small (~6 KB minified, no jQuery), conditionally enqueued only when a form is present on the page.
What you get
How it works in Core Forms
Conditional enqueue
Script only loads on pages that actually render a form. Most of your site stays JS-free.
Optional non-AJAX fallback
Per-form toggle to fall back to standard form submission if AJAX is off.
