How to execute custom javascript code inside an rjs template

I’d like to execute a piece of javascript code, for example
funcion f1() {
alert(‘test’);
}

in an rjs template

“page[:ticket_being_deleted].visual_effect :fade” I know this executes
some javascript, but is there a way that instead of this javascript
code, I execute f1 function?

Thanks in advance,
Marko Vuksanovic.

There’s an example for that here: #45 RJS Tips - RailsCasts,
in the screencast but also in the piece of code on the webpage.
Enjoy!
