You're confusing server side and client side code. Javascript works after a
webpage has been returned but Ruby works when a page is being fetched. So if
you want to be able to iterate over a bunch of values you'll need to create
a javascript array that contains the values of the Ruby array.

*If you want to convert it to a javascript array:*
http://api.rubyonrails.org/classes/ActionView/Helpers/JavaScriptHelper.html#M001761

I suggest you just make an array of titles and then pass it in via an
options array to your code or something to keep the view layer clean.

*So in your controller set:
*options[:title]
Equal to an array of the titles from your object array.

*Something like:*
var myEvents = <%= array_or_string_for_javascript(options[:title]) %>;

 for( var i = 0; i < myEvents.length; i++)
 {
alert (myEvents[i]);
}

Someone correct me if I'm explaining anything wrong or if there is something
wrong with my syntax -- I'm beginning ruby and rails myself so I think
that's the correct syntax.
