How to reference an item from GetElementsByName?

[gdrenfrew]

Hi,
I can't figure out how to reference individual items returned by getElementsByName . Can somebody help please?
This code only returns one item, but I cannot use the ID some must use the name, hence the use of getElementsByName rather than getElementByID

function()
{
var aInput = window.document.getElementsByName("Cell1&quot

alert(aInput.item()) etc just brings up null,
as does alert(aInput.item(0))

nb "Cell1" is the name attribute of a TD. I want to be able to reference that individual TD from my javascript, so I can change its colour.

Thanks
Graeme

If it only returns one item, it probably doesn't create the array....

alert(aInput) should return "[object]"

or else

alert(aInput.length) should return 1 meaning you have an array... Get the Best Answers! faq333-2924

Checked the getElementByName with IE 6 and this functions only seems to pick up form elements.
Mozilla does OK.

<input type=text name=&quot;somename&quot;>
<input type=text name=&quot;somename&quot;>
<input type=text name=&quot;somename&quot;>
<input type=text name=&quot;uniquename&quot;>

<input type=button value=test onclick=test()>

<div name=&quot;mydiv&quot;>content of the div</div>
<script>
function test(){
var arrItems = document.getElementsByName('uniquename');
alert(arrItems.length);
alert(arrItems[0].name);

var arrItems = document.getElementsByName('somename');
alert(arrItems.length);
alert(arrItems[0].name);

var arrItems = document.getElementsByName('mydiv');
alert(arrItems.length);
alert(arrItems[0].name); // this does not work in mozilla
arrItems[0].innerHTML = &quot;this works OK in mozilla&quot;;
}
</script>
