I wrote about an error which IE throws when you try to call focus() on
hidden element.

I know (see my very first post).

The simplest solution to that is in my reply to Thomas. Test the .type
property and if it is not type="hidden" then set focus.

You haven't looked at my first post.
OK! Let's try your "simplest solution: test the .type property and if
it is not type="hidden" then set focus":

<script type='text/javascript'>

function F() {
var o = document.getElementById('search');
if (o && o.type != 'hidden') {
o.focus();
};
};

</script>

<body onload='F()'>

<input type='text' id='search' style='visibility:hidden'>

</body>

What will happen in IE?

I did look at it. And that is why I also, in my first reply to you, said
it should check *both*.

> <input type='text' id='search' style='visibility:hidden'>

Just for kicks and giggles:

<input type="text" id="search" style="display:none">

And, since you made such a fuss about testing the visibility property
itself:

<div style="visibility:hidden">
<input type="text" id="search">
</div>

Personally, I think the entire discussion is nothing more than a mental
exercise. The simplest solution is the one Bart gave. If it throws an
error then the programmer needs to know it *then*, not let it be hidden
in a function somewhere.

Something, like this, can be more reliable (with hope that there are
no users of IE 5.0 and earlier):

function F() {
var o = document.getElementById('search');
if (o) {
if (o.setActive) {
o.setActive();
} else if (o.focus) {
o.focus();
};
};
};

But may be I'll choose select() method instead of two setActive/focus
(I wrote *may be*)...
