Showing an error when a JS-model submission is rejected

Published

Every JS-model form needs the result callback: put data-submit-result-callback="formResult" on the .coredna-js-form container and define window.formResult in the site's script. The platform calls it with the response first, for every answer including a 207, a 422 or a 500, and does nothing more when it returns false, so the callback shows the messages, keeps the answers and gives the buttons back.

The callback is in Add the platform's form scripts to a form layout, and with the jump back to an earlier step in Validation.
