APEX and Firebug
Firebug can be useful for checking images and their location, to check the version
of CSS, and JavaScript's currently loaded or used by an APEX application. Firebug
allows us to investigate our page, run and debug JavaScript, changing page styles
on the ly, and see which iles are missing.
The preceding screenshot shows images and stylesheets used in APEX in the
Firebug console.
The preceding screenshot shows the CSS sub-menu in the Firebug add-on.
Debugging dynamic actions
Debugging dynamic actions in Application Express is slightly different than
other debugging, because much of the processing done with the dynamic action
framework is done on the client, not on the server. In order to debug dynamic
actions, output the debug information to the browser's JavaScript console.
The Firebug add-on integrates with Firefox. You can edit, debug, and monitor
CSS, HTML, and JavaScript live in any web page. Firebug will show the debug
information in its Console pane.
The debug information will tell you when a dynamic action ires, the name of the
dynamic action, and also speciically which action has ired.
