Question

I’m having a very weird situation that is driving me nuts. I have a rails app that sends a simple string to jQuery and prints it out. Here is my code:

jQuery:

    jQuery(document).ready(function() {
    jQuery('.bid a').livequery('click', function() {
        obj = jQuery(this);
        jQuery.post(obj.attr('href'), function(data) {
            alert(data)
        });
        return false;
    });
    })

Rails Controller:

def send_message
    respond_to do |format|
      format.js do
          @res_str = "nobids"
          render :json => @res_str
      end 
    end
end

Like that, it works ok, it shows an alert with the string “nobids”. However, if I want to send any other string, lets say “nobidss”, it fails! It makes no sense at all!

What could be happening?

I was making a rookie mistake!

If you render :json you have to convert the response message to json, ie: @response.to_json.

Also, in the html, the href has to end in .json, and in the controller you have to respond to format.json too.

I cannot tell why it was succeeding with the string “nobids” anyways.

It works beautifull now
