IE workaround for :target psuedo-class

[bankfishin]

I know very little about javascript but have found a very convenient way to display a hidden div using css3. Problem is that IE can't handle it. There is a js workaround I found by suckerfish but it has one flaw. When I refresh the page I get an error. Here is the basic code.

Here is the JS code:

sfTarget = function() {
	var sfEls=document.getElementsByTagName("span");
	var aEls = document.getElementsByTagName("a");
	document.lastTarget = null;
	for (var i=0; i<sfEls.length; i++) {
		if (sfEls[i].id) {
			if (location.hash==("#" + sfEls[i].id)) {
				sfEls[i].className+=" " + cls;
				document.lastTarget=sfEls[i];
			}
			for (var j=0; j<aEls.length; j++) {
				if (aEls[j].hash==("#" + sfEls[i].id)) aEls[j].targetEl = sfEls[i]; aEls[j].onclick = function() {
					if (document.lastTarget) document.lastTarget.className = document.lastTarget.className.replace(new RegExp(" sftarget\\b"), "");
					if (this.targetEl) this.targetEl.className+=" sftarget"; document.lastTarget=this.targetEl;
					return true;
				}
			}
		}
	}
}
if (window.attachEvent) window.attachEvent("onload", sfTarget);

The html:

  <a href="#item1" name="a">item 1</a>
  <a href="#item2" name="a">item 2</a>
  <a href="#item3" name="a">item 3</a>
  <a href="#default" name="a">clear</a>


<div class="items">
  <span id="item1" class="content">... item 1...</span>
  <span id="item3" class="content">... item 2...</span>
  <span id="item3" class="content">...</span>
  <span id="default" class="content"><!-- by default, show no text --></span>
</div>

And this is the css:

div.items span {display: none}
div.items span:target {display: block}
div.items span.sftarget {display: block}

As I said it works fine in that it hides and displays the spans. Problem is that if I refresh the page I get an error and it stops working properly. Anyone want to look at the js and give me any advice??
