don’t get, what exactly you want to do

link\_to\_function “Greeting”, “alert(‘Hello world!’)”  
would create a link to a js function

otherwise you can implement onclick whereever necessary:  
onclick=“alert(‘Hello world!’);return false;”

or combine it with onsubmit etc.

I think the prototype equivalent is

$$(‘a’).onclick = function(){  
}

however I am also more partial to the JQuery way. I have yet to have a  
problem making them work together.

Just get this order right and you should be fine:

include jQuery  
call “var J = jQuery.noConflict()”  
include prototype

J(‘a’).click(function(){})

simple with jQuery !

jQuery(‘a’).click(function(){  
my nice code here  
});

although, getting jQuery working with prototype is bit tricky. i use  
jrails javascript files, but WITH prototype.
