submit( )

Submits a Wix Form.

The submit() function does the following:

1. Performs built-in, general validations (such as checking that all email fields contain valid email addresses).
2. Calls onSubmit(). If the form fields do not pass validation, the submit() function returns the SUBMISSION_ERROR.VALIDATION_FAILED error and the submission of the Wix Form data to the server is aborted.
3. Sends a request to the server to create a submission.
   If the request is successful:
   1. Calls onSubmitSuccess().
   2. Resets form field values.
   3. The submit() function returns an object with the submitted values. If the request fails:
   4. Calls onSubmitFailure().
   5. The submit() function returns an error.
