attributes

I have a regular input box (no onchange attribute).

<input type="text" id="bar" name="bar" />

For some reason, IE6+ does returns [object], while FF and Chrome returns null.

if ((elem.getAttributeNode('onchange')) != null)
  elem.onchange();

I did also try as:

if (typeof(elem.onchange) !== 'undefined')
  elem.onchange();

What would be the proper cross-browser way to check if the element has the attribute?

Thanks
