Unable to set focus in Firefox/Opera

Question

Setting focus on a form element using JavaScript is usually very straight forward. I cannot get this working in Firefox 12.0 or Opera 11.

Works in other browsers (Chrome, IE etc) and Firefox 3.6.

Simple HTML:

<form action="">
    <input type="radio" id="focusID1" name="sex" value="male" /> Male<br />
    <input type="radio" id="focusID2" name="sex" value="female" /> Female<br />
</form>

​Simple Javascript:

var elem = document.getElementById("focusID2");
if (elem != null) {
   elem.focus();
}

Try this for yourself at http://jsfiddle.net/4Ddtv/. ​

Answer 1

Firefox was working as expected. Issue was with jsfiddle focus and firefox not highlighting the focused element.

This is not an issue.. User error!
