popup message javascript alert in pre-execution

[Poyato]

It is possible to run a javascript that displays a popup in a pre execution of a module in the PAM?
Something like:
alert ("I am an alert box!");

No, it fails with the error message: "ReferenceError: 'alert' is not defined.". Even if the command worked, the alert box would require and interactive session with the process, which you don't have. My guess is that it would run and "hang", waiting on a button click.
