For example, the tracking inputs are through the focus and blur events.

4. Form Events

These interactions only occur on the form and form input elements.

The submit event is used to track whether a form is submitted or not.

The change event is used to listen to the user's input in an element.

The Select event is triggered after the <SELECT> </SELECT> element is updated.

5. Loading and error events

Listen to its own loading status.

When the user loads the page (load event) for the first time and the user leaves the page (unload and beforeunload events), it is bound.
