title: blur (evento)
slug: Web/Events/blur
translation_of: Web/API/Element/blur_event
---
<p>O evento <code>blur</code> é acionado quando um elemento perde foco. A diferença principal entre este evento e <a href="/en-US/docs/Mozilla_event_reference/focusout"><code>focusout</code></a> é que apenas o segundo 'borbulha'.</p>

<p>{{NoteStart}}O valor de {{domxref("Document.activeElement")}} varia entre navegadores enquanto este evento é processado ({{bug(452307)}}): O IE10 define-o para o elemento para onde o foco moverá, enquanto Firefox e Chrome muitas vezes definem-o para o <code>body</code> do documento.{{NoteEnd}}</p>

<h2 id="Delegação_do_evento">Delegação do evento</h2>
<p>Existem duas maneiras de implementar a delegação de eventos para este evento: usando o evento <code>focusout</code> nos navegadores que suportam-o, ou definindo o parâmetro "useCapture" do <a href="/en-US/docs/DOM/element.addEventListener"><code>addEventListener</code></a> para <code>true</code>:</p>
