change from rewriting <a> tags to requiring callout
this question is regarding a problem i posted re: earlier, but perhaps approaching it from a different position might be easier.

how would i change this script so it did NOT rewrite all links with the onmouseover and onmouseout events, but did enable me to use those by indicating onmouseover=transOn etc. within each <a> tag i wanted to apply it to?

<script type="text/javascript">
function initTrans()
{
	for(var i=0 ; i<document.links.length ; i++)
		if(document.links[i].className == "textTrans")
		{
			var lnk=document.links[i];
			lnk.onmouseover=transOn;
			lnk.onmouseout=transOff;
		}
}
function transOn() 
{
	if(this.filters != null) this.filters[0].stop();
	if(this.style)
	{
		this.style.backgroundColor = "#470509";
		this.style.color = "#111111";
	}
} 
function transOff() 
{ 
	if(this.filters != null) this.filters[0].apply();
	if(this.style)
	{
		this.style.backgroundColor = "#FFFFFF";
		this.style.color = "#470509";
	}
	if(this.filters != null) this.filters[0].play();
} 
</script>
