<p class="desc"><strong>Description: </strong>Selects element if it is currently focused.</p>
<div class="longdesc"><p>As with other pseudo-class selectors (those that begin with a ":"), it is recommended to precede <code>:focus</code> with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare <code>$(':focus')</code> is equivalent to <code>$('*:focus')</code>. If you are looking for the currently focused element, <code>$( document.activeElement )</code> will retrieve it without having to search the whole DOM tree.</p></div>
