Creating an event listener

The following is an example of how to create an event listener.

This listener is checking that the iframe has finished loading and that the entire form has been validated. You could use something like this to make your submit button inactive so that users cannot click on it until the form errors are corrected.

Example
window.addEventListener('message', function messageListener(event) {
  if (event.origin === iframeUrl) {
    const eventData = event.data?.data;
    const eventType = event.data?.event;

    if (eventType === ‘loaded’) {
      // iframe successfully loaded.
    }

    if (eventType === ‘formValidations’) {
      const jsonData = JSON.parse(eventData);
      if (jsonData.isFormValid) {
        // form is ready to submit.
            }
      }
      // switch on event.data properties
      // (e.g. loaded, formValidations, error)
    }
});
