AutoAction - Javascript support

Hi,
I'm trying to get some javascript inline executed.
for troubleshooting, I tried for example some
Windows.open(" mysite.com ");
but nothing is happening.
I assume it is somehting related maybe to the fact we need to do return or echo something ? ( my guess is this as I tried as well console.log, and I get nothing in the console).
Thanks for your insights

Use a Code action with Method set to JavaScript (Inline) then supply your JS. that's all you'll need to do, but this assumes you're using a trigger that actually has output. For example outputting JS during a save operation won't do anything as that has no display. Outputting JS before or after profile display for example will work.

Trigger is " joomla_OnAfterUserLogin", so there is a lot displayed ( and relaoded ) no ?

Nothing displays during that trigger. That's during a PHP login operation. Immediately after that trigger is a redirect. So there is no output during that trigger.

ah ok , make sense then ..
will try to find another event then ....
thx
