Error: document.getEle mentById("ff") has no properties

Hi

I want a form field to be selected when the page loads.

But I get the error message
Error: document.getEle mentById("ff") has no properties

any ideas what I am doing wrong?

code below

<script type="text/javascript">
function setfocus()
{
document.getEle mentById('ff'). focus();
}
window.onload = setfocus();
</script

<form>
<input type="text" id="ff" >
</form>

Passing the result of setfocus(), rather than a reference (see below).

Nothing to do with your problem, but it is considered better to use the
forms collection rather than getElementById - it is more widely
supported and faster. You should also test for the focus method before
trying to call it:

var el = document.forms[0].elements['ff'];
if (el.focus) el.focus();

}
window.onload = setfocus();

Your issue is here:

window.onload = setfocus; // Remove ()

window.onload = setfocus();

should be:

Not a solution really as a property accessor in the position where an
Identifier is expected in a function declaration is a syntax error
(which is tolerated in IE but won't pass many other browsers without
complaint).
