How do I Update Javascript Event Tracking Code to Not Track Internal Javascript Links as Outgoing Links in Google Analytics

Hello, I have been using the following javascript to track outgoing links on our asp.net website www.competitiveedgeproducts.com and it is working pretty good except that it is also tracking javascript links on the website that don't take people to another site as Outgoing links.  For example it is tracking a lot of javascript links like this:
javascript:{if (typeof(Page_ClientValidate) != 'function' || Page_ClientValidate()) __doPostBack('SearchTemplate13$DataGrid1$_ctl19$_ctl1','')}

and classifying them as an Outgoing Link which I don't want.  Could anyone tell me what to change in this code to track internal javascript links as Internal links instead of outgoing links or not even track them with this code?
 

<script type="text/javascript">
/* Attach tracking to all download & external links */
var _gaq = _gaq || [];

function _gaLt(event){
	var el = event.srcElement || event.target;

	/* Loop up the tree through parent elements if clicked element is not a link (eg: an image in a link) */
	while(el && (typeof el.tagName == 'undefined' || el.tagName.toLowerCase() != 'a' || !el.href))
		el = el.parentNode;

	if(el && el.href){
		if(el.href.indexOf(location.host) == -1){ /* external link */
			_gaq.push(["_trackEvent", "Outgoing Links", el.href, document.location.pathname + document.location.search]);
			/* if target not set delay opening of window by 0.5s to allow tracking */
			if(!el.target || el.target.match(/^_(self|parent|top)$/i)){
				setTimeout(function(){
					document.location.href = el.href;
				}.bind(el),500);
				/* Prevent standard click */
				event.preventDefault ? event.preventDefault() : event.returnValue = !1;
			}
		}

	}
}

/* Attach the event to all clicks in the document */
var d = document;
d.addEventListener ? d.addEventListener("click",_gaLt,!1) : d.attachEvent && d.attachEvent("onclick",_gaLt);
</script>
