Sinatra is told to response with JSON

befor         


        

Answer 1

Thank's for the answers so far. You were right and jsonp would solve the problem. The code snippets for javascript work fine. To set up Sinatra is very easy as it is build on top of Rack. Therefore simply install the rack-contrib gem

 gem install rack-rack-contrib --source=http://gems.github.com/

(or put it in your Gemfile) and add

require 'rack/contrib/jsonp'
use Rack::JSONP

to your application.

This middleware provides regular JSON to non-JSONP clients and JSONP to jQuery & co.
