IF it is disabled it cannot obtain focus so you "detect" it by detecting 
the focus is *not* on it.

It shifts but not to the disabled control. Use tab or click and see for 
yourself:


<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
	"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
	<title>template</title>
	<script type="text/javascript">
	function announce(me){
		var msg=document.getElementById('status');
		msg.firstChild.nodeValue='Focus on ' + me.id;	
	}
	</script>
	
</head>
<body>

<form>
<ul>
<li id="status">Status</li>
<li>
	<label>foo</label>
	<input type="text" name="foo" id="foo" onfocus="announce(this)">
</li>
<li>
	<label>bar</label>
	<input type="text" name="bar" id="bar" disabled onfocus="announce(this)">
</li>
<li>
	<label>baz</label>
	<input type="text" name="baz" id="baz" onfocus="announce(this)">
</li>
<li>
	<label>bin</label>
	<input type="text" name="bin" id="bin" onfocus="announce(this)">
</li>
</ul>
</form>

</body>
</html>
