How do you access non-standard attributes in Firefox JavaScript?

Question

Basically in IE you can do something like this:

<img metaDataAtt="type5" src="..." id="tag1"/>

and then in the JavaScript do something like

var theImg = document.getElementById("tag1");
alert(theImg.metaDataAtt);

However, in firefox you can't. Is there some sort of hack to get around this?

Thanks, Grae

Just tested it, works for Firefox. Does it work for IE also? It seems like it probably will.

I know this is a little old, but how do you set those attribute from JavaScript?

@Grae document.getElementById('tag1').setAttribute('metaDataAtt', 'foo');
