     <p>The <code>blur</code> event does not bubble in Internet Explorer. Therefore, scripts that rely on event delegation with the <code>blur</code> event will not work consistently across browsers. As of version 1.4.2, however, jQuery works around this limitation by mapping <code>blur</code> to the <code>focusout</code> event in its event delegation methods, <a href="/live/"><code>.live()</code></a> and <a href="/delegate/"><code>.delegate()</code></a>.</p>
