<p>Um manipulador de eventos que aborta eventos enviados para a janela. (Não disponível para o Firefox 2 ou Safari)</p>

<p>TODO define what "abort" is. Closing the window via window manager? Stopping the load of the page? By which means and reasons (user, network/server)? At which stages would it fire / be catched? For IE, onabort is only available with <code>img</code> tags.</p>
