Call JavaScript Function in PL/SQL

Question

Hello All,
I need to call a JS function to open a popup, I'm in the middle of a PL/SQL Process that I use:
   V_ERRO_VALIDACAO := 'S';
  IF V_ERRO_VALIDACAO = 'S' THEN
    HTP.p ('<script type="text/javascript">');
    HTP.p ('javascript:popUp2(''f?p=&APP_ID.:21:&SESSION.::NO::'', 700, 400);');
    HTP.p ('</script>');
  END IF;
  --But it's not working.
It's hard coded for testing purposes
Is there a way to call the popup in the process?
Thanks,
Alan Martini.

If you want to combine PLSQL and JS code, rely on Dynamic Actions with true actions of different types executed based on their sequence (PLSQL ,JavaScript and possibly some set Item process to pass values between JS - PLSQL ).
For example
**True Action 1 : PLSQL code
**True Action 2 : Set Item value (fetches from DB after last change )
**True Action 3: Run JS code based on page item
**True Action4: Run PLSQL based on JS action
If you want more flexibility to pass around values, use Ajax(callback process and javascript) but you would loose the declarative coding style and probably end up making the code difficult to maintain.
