Cross domain load request

Hello mates

I would like to load on my forum portal (in a widget for example) a div class of another page

for example I want to load on my forum the elements div.listing li from a page www.domain.com/hello, that is different from my domain (so i cannot use .load()


What can I do?

.load not allow to loading elements other domain..
trying $.get() or $.ajax()

yes, I know I should use ajax, but I cannot understand how to set up the code

Try:
api.jquery.com/jQuery.getJSON/
api.jquery.com/jQuery.Ajax/

Please not ads

HTML:

Code:

<div id="images"></div>

JS:
Initialize resource of external pages.

(function() {
  var flickerAPI = "//api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?"; // External link
