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.

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.

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(){})
