Prototype Constants replacement in v5.4`

Hi,

We have been using the following constants in our program but they no longer work as we are removing Prototype.
Can you please suggest the replacements of these constants in Tapestry v5.4.

Tapestry.FORM_PREPARE_FOR_SUBMIT_EVENT
Tapestry.ZONE_UPDATED_EVENT
Tapestry.currentFocusField
Tapestry.FOCUS_CHANGE_EVENT
Tapestry.FORM_PROCESS_SUBMIT_EVENT
Tapestry.ajaxExceptionHandler
Tapestry.ajaxFailureHandler
