How to access Oracle Apex variables from Javascript?

Question

I use Oracle APEX, but I don’t know how to access the following variables from an external javascript file, which can be located on the application server or stored in shared components → Static files.

:APP_ID :APP_PAGE_ID :APP_SESSION 

How can I reference the values ​​for each of the above from javascript (stored as a static file)?

Answer 1

These values ​​are displayed on the page as hidden elements, such as:

 <input type="hidden" name="p_flow_id" value="4000" id="pFlowId" /> <input type="hidden" name="p_flow_step_id" value="4150" id="pFlowStepId" /> <input type="hidden" name="p_instance" value="6528421540413702" id="pInstance" /> 

so that you can refer to them as:

 $v('pFlowId') // APP_ID $v('pFlowStepId') // APP_PAGE_ID $v('pInstance') // SESSION 

Too bad they are not named the same as the state of the session!
