check presence of an HTML element

In Netscape6.0 and IE5.5 and greater, how do I check to see if a HTML element is present ?
Say for example, I have a hidden field

<input type="hidden" name="testField" value="something">

So if the "testField" element is present I want my code to do something or else do something else.

Any ideas ? Thanks in advance.

if (document.getElementsByName('testField').item(0)) {
//it exists
}

Thanks. It works :)
