I guess you have assigned longitude and latitude as variables which is accessible by your ajax request. If its not you will not get anything in the controller. Make sure the variables scope is right , then try this :

jQuery.ajax({
          url: 'main/getlocation',
          data: "latitude=" + latitude + "&longitude=" + longitude,
          type: "POST",
          success: function(data) {
            alert("Successful");
          },
          failure: function() {
            alert("Unsuccessful");
          }
        }); 

Now, I guess you can get the params[:longitude] and params[:latitude] in your controller.
