Implementing specific actions based on user selections in an Oracle APEX navigation bar

Within the application's navigation bar, there is a Home item that is present on all pages. I want to implement a feature where if the user clicks on the Home item, a warning message will pop up based on the page number, alerting them that any unsaved work will be lost. If the user selects 'yes', they will be directed to the application's home page without any work being saved. If they choose 'no', they will remain on the current page.

Currently, the warning dialog appears on every page. In Oracle Application Express, under 

shared components > navigation bar > target area
, here are my settings:

Target type = url

URL target = 

javascript:if(confirm('All unsaved work will be lost?')) 
{window.location.href ='f?p=&APP_ID.:1:&SESSION.:&APP_PAGE_ID.';}

I want this functionality to be limited to specific pages. If a user clicks on a page that is not on the designated list, the warning message should not appear and they will be directed to the application's home page.

If you're looking for a way to create a dynamic action that targets navigation bar entries, you might find it challenging. Selectively enabling or disabling this action on specific items is not a straightforward task, as you would need to test the text of the anchor tag by hardcoding values in your dynamic action. This approach is not ideal.
There are no classes or onclick events that can be easily utilized for this purpose.
One potential solution could involve using the provided code snippet and creating a JavaScript function that takes a page id as an input parameter. This function would then compare the page id against a list of pages where the action is allowed. However, this method can be quite complex. It could be simplified by incorporating some AJAX functionality, but given your unfamiliarity with JavaScript, it might be best to first familiarize yourself with the language.
Instead of trying to develop a custom solution, you may want to consider using a pre-existing save before exit plugin. This plugin is designed to detect unsaved changes and can be easily added to specific pages where you want this functionality.
