Using global form events

Forms allow two ways to bind functionality onto events; embedded callbacks in the HubSpot form embed code, discussed here, and global events, discussed in this doc. This is a list of all global events that are emitted by HubSpot forms, and can be used to trigger custom JavaScript. If you need complete control over the styles and actions of your form, we recommend building your own custom form and submitting the data using the Forms API.

Please note: These events are non-blocking, so it's not possible to prevent a form submission using the onFormSubmit callback.
