<%= link_to( {:controller => 'board',

in rails2, there were :before, and :complete params, but I have not found any documentation for this in rails3
As I understand it, this is one of the consequences of Rails 3 using UJS (unobstrusive javascript). Rails 3 enables you to keep the javascript away from e.g. a link-tag. Instead of the link-tag specifying what should be done via javascript, you make the javascript observe the link-tag.
You achieve this by binding a function to a certain event of an object, eg. binding the ajax:before event of the link-tag to a function.
In this blog post the author explains how to do it, in his case with JQuery.
As far as I understand, in Rails 3 you bind the callback events to the element on the client side, and they are fired by rails.js at the appropriate times.
$('#myform').bind('ajax:success', function(){
alert('I succeeded');
})
If I remember well, there is no more support in Rails3.
You could use native jQuery function:
ajaxStart()
http://api.jquery.com/ajaxStart/
See details here: http://www.simonecarletti.com/blog/2010/06/unobtrusive-javascript-in-rails-3/
My version (jquery-rails 0.2.6) supports ajax:before, loading, success, complete, failure, and after. The parameters to the success/failure functions are not the same which has tripped me up in the past. But the following works for me:
$('a').bind('ajax:loading', function() {
alert('here');
});
If your link element was created after the initial page load, you might need to bind using 'live':
$('a').live('ajax:loading', function() { alert('...'); });
I would also double-check that your onclick handler is not interfering.
