Explanation of the URL:</p> <ul> <li>Base URL: <a href="http://graph.facebook.com/?ids=http://legrandj.eu/article/blouse_ghost_dream" rel="nofollow">http://graph.facebook.com/?ids=http://legrandj.eu/article/blouse_ghost_dream</a></li> <li>Callback handler: <code>&callback=jQuery171022388557461090386_1332329918803</code><br> <strong>jQuery replaces <code>?</code> in <code>callback=?</code> with an unique temporary identifier</strong>.</li> <li>Cache-breaking: <code>&_=133232991983</code></li> </ul> <p>The FB API returns a response in the following format (<a href="http://en.wikipedia.org/wiki/JSONP" rel="nofollow">JSONP</a>):</p> <pre><code>/**/ jQuery171022388557461090386_1332329918803({ "http://legrandj.eu/article/blouse_ghost_dream": { "id": "http://legrandj.eu/article/blouse_ghost_dream", "shares": 3 } }); </code></pre> <p>Since this is included by the <code><script></code> tag, a function <code>jQuery171022388557461090386_1332329918803</code> is called, passing the parsed JSON as an argument. The parsed JSON is then passed to the function which you defined in <code>jQuery.getJSON</code>.</p>
