<p>O evento <code>focus</code> é acionado assim que um elemento recebe um foco. O grande diferencial entre este evento e o evento <a href="/en-US/docs/Mozilla_event_reference/focusin"><code>focusin</code></a>, é que esse segundo "borbulha".</p>

<h2 id="Eventos_Delegados">Eventos Delegados</h2>

<p>Existem 2 maneiras diferentes de implementações delegados a partir de um evento: por meio da utilização do evento  <code>focusin</code> que todos os browsers atuais suportam tão tecnologia (todos exceto o Firefox), ou por setando o parâmetro "useCapture" do elemento  <a href="/en-US/docs/DOM/element.addEventListener"><code>addEventListener</code></a>  como <code>true</code>:</p>

<p>{{ EmbedLiveSample('Event_delegation', '', '', '', 'Web/Events/blur') }}</p>

<p>(Exemplo de codigo do evento <a href="/en-US/docs/Web/Events/blur">blur (event)</a>)</p>
