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();
}
