<p>I know this shouldn't be difficult, but I can't find the answer on Google. </p>
<p>I want to execute a piece of javascript code that can clear the element where the current focus is, without knowing in advance which element the focus is on. It must work on Firefox 2 and more modern browsers. </p>
<p>Is there a good way to achieve this function? </p>

.focus()Then select any other element.blur()on your page. Since only one element can have focus, focus is transferred to that element and then removed.Answer:
document.activeElementTo achieve the effect you want, use
document.activeElement.blur()If you need to support Firefox 2, you can also use the following code:
function onElementFocused(e) { if (e && e.target) document.activeElement = e.target == document ? null : e.target; } if (document.addEventListener) document.addEventListener("focus", onElementFocused, true);
