How to detect an form object

[Zimbo2]

Hi,

I want to set the focus to a form object like
document.form1["objectName"].focus().

This works fine. But only if "objectName" exists. How can I find out if it exists?

Thanks in advance

if (document.form1["objectName"])
{ // yes, it exists }
else
{ // huh? }
