.className not working in IE

[admin]

I am using a javascript function to show some hidden elements on a page. Following is the piece of javascript code.

var itemArray = document.getElementsByName('hiddenItem');

for(i=0;i<itemArray.length;i++){
itemArray.className='pageSummary_cell';
}

The hiddenItem have a class where their display is set to none. When I set the className to pageSummary_cell, the items are displayed in firefox but not in IE. can anybody suggest a solution to it?

Thanks in advance
gauravHave a look at this

function hideSpans() {
var Spans = document.getElementsByTagName('span');
for(var i=0; i < Spans.length; i++) {

if(Spans.className=='someClass') {

Spans.className='pageSummary_cell';
}}}

Of course you can change the tag name to whatever you need it to be.
