submitcomplete

Submitcomplete is a term used in some web development libraries to indicate the moment when a form submission has finished processing on the client and server. It typically marks the point at which the server response has been received and any post-submission UI updates have been performed. There is no universal standard for a submitcomplete event; the exact name, payload, and trigger vary by framework or library, and some ecosystems do not use this term at all. Variants such as submitComplete or onSubmitComplete may appear in different APIs.

In libraries that implement it as an event or callback, submitcomplete fires after the submission has completed, including both success and error responses. Handlers commonly re-enable input controls, display success or error messages, update parts of the page, or reset the form. The event may deliver data such as the HTTP status, response body, and a reference to the form or submission object. The exact lifecycle and naming depend on the specific library, so developers should consult the relevant documentation to understand what is provided with the event and how it interacts with error handling, retries, or progressive enhancement.

With modern techniques, many developers use the Fetch API or promises to manage submissions and then run a finalization routine on completion, rather than relying on a dedicated submitcomplete signal. When used, careful attention should be paid to cross-origin constraints, CSRF protections, and consistent user feedback.
