How do I actually use this workaround to get the example you gave working?

this.parentNode.parentNode.removeChild(this.parentNode);

function addEvent(elem, evt, handler)
{
if (typeof elem.addEventListener !== ‘undefined’)
{
elem.addEventListener(evt, handler, false);
}
else if (typeof elem.attachEvent !== ‘undefined’)
{
var proxy = function() { handler.call(elem); };
elem.attachEvent(‘on’ + evt, proxy);
}
}

Bear in mind though, that this will make it impossible to detach the event in IE (that may not matter to you).

Another option is to use a cross-browser addEvent function from some javascript library. The Gimme Javascript Libaray (http://codelpex.com/gimme), for example, lets you take any DOM element and do:

g(myDomElem).addEvent(‘click’, someHandler); // works in all browsers

Hope this helps!
