I am currently developing a Ruby on rails 3 application.

My server controller function render a json object as response:

class DaysController < BaseController
   ...
   def the_days
     ...
     render :json => days
   end
end

In my javascript,I use the following code to get json response from server( that's from the_day function in controller)

$.getJSON(  
             url,  
             {emp_id: emp_id},
             function(data) {
                     var result = data.response;
                     alert(result) 
                     alert(data)
                 },
                 "json"
        );

I use firefox browswer and checked with Firebug, in Firebug Net->XHR, I see the Get request is successful, and the response "days" is there. That's both request and response are successful.

But I did not see the two alert window defined in the above $.getJSON function, why? Why I can not get the response "days" in $.getJSON function??
