Rails - Mar 2006 - Ajax callback to javascript array ?

I have some javascript,

<script>
var arrCustomers;

function setCustomers(arr)
{
   arrCustomers= arr;
   // arrCustomers holds now array of customers
}
</script>


... and Rails controller,

class CustomersController < ApplicationController
    def list
        @customers = Customer.find_all
    end
end


... and Ajaxed link to get the customers,

<%= link_to_remote "Get customers",
    :url=>{
    :controller=>"customers",
    :action=>"list",
    :complete=>"setCustomers( ''what should i put here
????'' )"
%>

I want to populate the javascript array with the response of the Ajax
call to my CustomersController. The javasript callback function
''setCustomers'' gets called but I do not know how to pass
customers as a
parameter?

Can you help me?

nano,
This is just one way.  Use the XMLHTTP object and write the return to 
the arrCustomers variable.
