- 6. Intro Client side code that makes your applications ‘alive’ Declarative code without or little knowledge of JavaScript Introduced in APEX 4.0 Event driven (for example by user actions) They are your events manager where some components publish events and some subscribe to it Easy to learn Expandable with plugins architecture
- 7. Material By installing Sample dynamic action By installing dynamic-actions.com Or many available webinars and online materials Check out ODTUG KScope materials or AUSOUG webinar series
- 8. Key notes WHEN event is the trigger (can be Browser, Framework or component initialted; example dialog closes button is clicked) ACTION what does it need to do ie. set value; refresh region AFFECTED ELEMENTS what element does the action influences. It is optional usually something like page item or a region
- 9. How to create them? Select component Give DA a name that describes action Select an event Optionally define affected element Apply correct event scope

- - client side code that makes your applications live - declarative without or little knowledge of Javascript - you can still use custom JS if more prone to it - Introduced in APEX 4.0 - event driven (user actions ) 30+ events 21 native actions - can be extended by plugins - different component types can have events that can be exposed with plugin architecture - you can debug it in console with same switch for DEBUG what and where firing - easy to learn webinars -> kscope/ausoug
- Anything user can do is browser event framework - After refresh before etc... component - Interactive gird Refresh and plsql are special as they do requests to the servers Event listener - is part of dynamic actions; Attaches listener to an event event delegation; to element higher up event bubling
