+<p>La propiedad <strong>onfocus</strong> devuelve un manejador de eventos para el evento onFocus en el elemento actual.</p>

+
+<p>El evento focus se dispara cuando el usuario establece el foco en el elemento.</p>
+
+<p>Para que el evento <code>onfocus</code> se dispare en elementos que no sean inputs, los mismos deben establecerse con el atributo  {{htmlattrxref("tabindex")}}  (vea <a href="/en-US/docs/Learn/Accessibility/HTML#Building_keyboard_accessibility_back_in">Building keyboard accessibility back in</a> para mas detalles).</p>
+
+<p>A diferencia de MSIE, en que casi toda clase de elemento puede recibir el evento focus,  en los navegadores Gecko en los que casi todos los elementos NO reciben este evento.</p>
