title: Which javaScript framework for cross-domain?
body: <p>I am building a web service that will make heavy use of cross-domain GET and POST data, and then update some lightbox or similar windows on the client.</p>
  
  <p>Is there one JavaScript framework that is better at this, or more importantly, a framework which I should avoid?</p>
  
  <ul>
  <li><p>I want to be able to put controls in the boxes. Really sexy boxes would be nice. These will be updated without page reloads.</p></li>
  <li><p>Framework needs to be really good at the cross-domain stuff. I need good error trapping and process confirmation so that I can show the user that his connections are active.</p></li>
  </ul>
  
  <p>I can use more than one framework if necessary. The bandwidth might be justified if one framework was really good at cross-domain and another was really good at windows/boxes.</p>
  
  <p>Thanks,</p>
  
  <p><em>EDIT: With regard to which frameworks to avoid, I am thinking in terms of gotchas.</em></p>
